Transferring an outside call . . .
. . . to another station
Blind transfer
- While connected to an outside call, press a station key (or press TRANSFER and then dial the extension number).
- Hang up immediately to perform a blind transfer.
Note:
If the called party does not answer, the caller will be forwarded either to the called party’s mailbox or another destination the Installer has programmed.
Supervised transfer — announcing the caller to the called party
- While connected to an outside call, press a station key (or press TRANSFER and then dial the extension number).
- Do not hang up; instead, wait until the called party answers.
- Announce the caller (e.g., “Hello; I’ve got Bill on the line and I’m transferring him to you now.”)
- Hang up, completing the supervised transfer.
Note:
If the transferred-to party does not answer in step 1, press the station key again or press FLASH to be reconnected to the original caller.
. . . to another phone number (trunk-to-trunk transfer)
Available on IVX 128 Plus, IP 200 and IP 40.
This feature must be enabled by your System Administrator before you can use it.
IMPORTANT:
USE OF FEATURES, SUCH AS TRUNK-TO-TRUNK TRANSFER, THAT REQUIRE TRUNK-TO-TRUNK CONNECTIONS WILL INCREASE THE RISK OF TOLL FRAUD. IN NO EVENT SHALL ESTECH SYSTEMS, INC. BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES WHATSOEVER INCLUDING, BUT NOT LIMITED TO, FRAUDULENT TOLL CHARGES, LOSS OF BUSINESS PROFITS, BUSINESS INTERRUPTIONS, OR ANY OTHER COSTS OR DAMAGES RELATED THERETO, ARISING FROM THE USE OF THESE FEATURES.
Blind transfer
- While connected to an outside call, press TRANSFER and then the line access code (9, 8, or 71–76 [7 on IVX 20 Plus]), and then the telephone number to which you want to transfer.
- Hang up immediately to perform a blind transfer. Now both CO
lines are connected via a trunk-to-trunk connection.
Note:
If, at any point during the trunk-to-trunk transfer, you wish to return to the original call — perhaps you received a busy signal at the remote end, or the recipient simply won’t take the call — just press FLASH. This will disconnect the second CO connection, returning you to (and removing from hold) the original call.

Transferring a caller to a mailbox to leave a message
- Press VOICEMAIL and the appropriate station key — or, if your phone has no station key programmed for this destination, press VOICEMAIL and TRANSFER and then dial the extension number.
- You and the caller will be connected to that user’s personal greeting.
You may choose either to hang up immediately or listen to a portion of the personal
greeting (i.e., to assure yourself that you have placed the caller into
the correct mailbox).
Note:
Regardless of when you hang up, the caller will hear the entire personal greeting. To insure the privacy of the message, you will automatically be disconnected at the record tone.
Transferring a user to his/her own mailbox for message pickup
You can transfer a user who’s calling from the outside directly to his/her mailbox for message pick-up by pressing VOICEMAIL ∗ and the appropriate station key, or dialing the mailbox number and hanging up.
. . . to the main greeting
To transfer an outside caller to the main greeting, press VOICEMAIL and hang up.

Conference calling
To create a conference call:
- Establish the first call.
- Press CONF. This places the call on hold.
- Place a second call as you normally would.
- Once connected to the second call, press CONF again to connect together the three of you.
- Repeat these steps to add additional parties to the conference.
If the newest added-on party does not answer, press his/her station key again or press FLASH to return to the original conferees. If you place any incoming caller on park (see “Park/hold operation”) or hold, you can add that caller, too, to the conference by pressing CONF, retrieving the call from park or hold and pressing CONF again.
Any member of the conference can drop out by simply hanging up. However, when the station that created the conference hangs up, all parties in the conference are disconnected. Individual stations or lines connected to the conference can be dropped from the conference by pressing their station or line key (lit green).
Notes:
A total of 24 parties (except on IVX 20 Plus, on which the maximum is eight) can be in conferences within the system at any one time.
No more than four parties can be in a single conference.
Your installer or system administrator may have enabled trunk-to-trunk* conferencing (unsupervised conferencing) for your station. If so, the steps to
initiating such a conference are the same as for performing any other conference (see above); the difference is that you may hang up, thus exiting the
conference, but the remaining parties won’t be disconnected. (If this feature isn’t enabled, your hanging up disconnects all parties.)
IMPORTANT:
USE OF FEATURES, SUCH AS TRUNK-TO-TRUNK TRANSFER, THAT REQUIRE TRUNK-TO-TRUNK CONNECTIONS WILL INCREASE THE RISK OF TOLL FRAUD. IN NO EVENT SHALL ESTECH SYSTEMS, INC. BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES WHATSOEVER INCLUDING, BUT NOT LIMITED TO, FRAUDULENT TOLL CHARGES, LOSS OF BUSINESS PROFITS, BUSINESS INTERRUPTIONS, OR ANY OTHER COSTS OR DAMAGES RELATED THERETO, ARISING FROM THE USE OF THESE FEATURES.

Call forwarding
Your station has been pre-programmed by the installer to call-forward your phone when it is busy or does not answer (usually to your mailbox). In addition, you can temporarily call-forward all of your calls to another station or another user’s mailbox:
- Lift the handset.
- Dial 5 6 5.
- Dial the extension number (or press VOICEMAIL and then dial the mailbox number) to which the system should forward all calls.
Note:
If the forwarded-to station is busy or does not answer a forwarded call, the call will be returned to your mailbox.
To turn off call forward, dial 5 6 5 without selecting a destination and hang up.
If you frequently call-forward your phone, you can program a programmable feature key as a call forwarding key to automatically turn forwarding on and off. If you always forward to the same extension, you can program a key with both 5 6 5 and the extension number. (For more information, see “Programmable feature keys.”) The call forwarding key will be solid green to indicate that it is active.

Call waiting
If you have enabled call waiting for your station (PROG/HELP 3 1) and a second call comes in while you are on another, you’ll hear a tone in your earpiece and the bottom line of your display will indicate that a second call is waiting. You can ignore the call waiting and it will be transferred to your mailbox (or other destination set by the installer). To toggle between the two calls, press FLASH. To drop either call, press RELEASE while connected to the call to be dropped: this disconnects the call and automatically re-connects you to the other call.
Call waiting display
Be sure to check the display when you’re using call waiting. Initially, the top line shows the name or number of your original call (depending on how the call was created) and the call duration. The bottom line shows the name or number of the call waiting along with the duration of that call. The arrow on the display will move between the top and bottom line, indicating to which call you are connected. Here’s an example:
- You’re connected to XYZ Company, when you hear a
beep and see that Joe Smith is calling:

(In this example, Joe’s call is being transferred to you; it’s been in the system for 31 seconds.) - You press FLASH and are connected to Joe. Notice how the arrow moves to indicate the change of connection:
Note:
If Caller ID is not used, the line number will appear instead of the caller’s name or number. If Caller ID is used, in some instances the local telephone service provider will only show a general caller status such as
UNAVAILABLE,PRIVATE, orNO DATA SENT.
Station-to-station call waiting
You can call, or transfer a call to, another station that is in use (as indicated by the fact that its station key, if one exists for it on your ESI Feature Phone, is glowing red). This generates a call waiting tone in the other station’s earpiece and puts a call waiting indication on the bottom line of that station’s display, as explained in “Call waiting display” (above). If the person ignores the call waiting, your call or the transferred call will be forwarded to the person’s mailbox (or other destination set by the installer).
Background announce feature
During call waiting, you can also make a brief, private background announcement to the station’s earpiece (if its user has enabled the background announce feature). A background announce key must have been programmed at your station by programming code 5 6 9 at a programmable feature key (see “Programmable feature keys”).
- During call waiting (as described previously), press and hold the programmed announce key to speak; the key will glow green if background announce is permitted or red if it isn’t permitted. The called station will hear your voice over the outside party’s voice. The outside caller, however, cannot hear you. The called party can respond by pressing FLASH, which places the original call on hold.
- Release the key when you are finished speaking.
Note:
The background announce feature works only between ESI Feature Phones, only if the called party has allowed call waiting and background announce, and if the called party is using his/her handset. The background announce key will be green (only if these conditions are met) indicating that a background announce can be made.

Park/hold operation
The difference between park and hold
Your ESI Feature Phone lets you put a call on either park or hold. Each puts a call into a standby mode, but here’s the difference between the two:
- Park allows anyone on your ESI phone system to retrieve the call. The system
stores parked calls in several park zones you’ll identify numerically —
e.g., “Park One,” “Park Four,” etc.
(How many park zones you have depends on how many incoming phone lines you have.)
For example, if you need to transfer a call to another station and know the person is in the building but not at his/her desk, you might page him/her to pick up a “call on Park One.” - Hold keeps the call exclusively where a user pressed HOLD, allowing no other station to retrieve it unless system-wide hold is enabled and line appearances are programmed on the phone (see “System-wide hold”).
Park
To park a call
While on an outside call, press the PARK key to park the call.
The PARK key LED will blink green on your phone and blink red on
all other phones. The display will indicate PARKED ON: XX (where XX is
the line number).

If your phone has line keys programmed, the corresponding line key will blink green. On other phones the corresponding line key will blink red.
Note:
The line numbers of calls that you have parked will remain displayed on the bottom line of your display until retrieved.
To retrieve a parked call
To retrieve the parked call from any idle phone, press PARK and dial its line number (e.g., press 1 2 for Line 12).
Notes:
If your phone has any line keys programmed (see
“Programmable feature keys”),
each will blink red when a call is parked on its lines; in such cases, just press
that line key to retrieve the parked call.
You can retrieve the oldest parked call by pressing PARK and then 0.
The display will help you choose the line number to retrieve. After you press PARK, the top line of the display will show how many calls are parked and the bottom line of the display will show all parked calls in the system. Newly parked calls are added from the right side of the display.

Note:
If more calls are parked than the display can show, each side of the display will show an arrow, indicating that more lines are parked.
Press the corresponding scroll key (either
to scroll to the left
or
to scroll to the right) to view the other parked line numbers.
Hold
To place a call on hold
Press HOLD to place an outside call on hold exclusively for the station you’re using. The HOLD LED will blink green. If your phone has line keys programmed, the corresponding line key will also blink green (it will show as busy at all other stations).
To retrieve a held call
To reconnect to a call on hold, press HOLD (blinking green) again. Or, if your phone has line keys programmed, press the corresponding (blinking green) line key.
Park/hold recall
If you don’t retrieve a parked or held call within a certain period of time (set
by the installer), your phone will “recall” it. You’ll hear three
short ring tones and the LCD display will show PARK RECALL XX”
(where XX refers to the line involved) or HOLD RECALL.

To answer the recall, lift the handset or press SPEAKER.
To perform another action — such as placing an outside call — during
a recall, you must first answer the recall and transfer it, park again, etc.,
and then place the call. R will appear on other phones’ displays
to show that the call is being recalled.
Note:
A park or hold recall will ring the extension six times, then follow the extension’s call-forward setting (the default is that it goes to the extension’s mailbox).
System-wide hold
Your Installer may have enabled this feature, which is used in conjunction with line key appearances programmed at your station. This allows you to press the HOLD key to place the caller on hold so that anyone with line key appearances programmed at his/her station can retrieve the call; the appropriate line key will blink green at your station and blink red at those other stations. To retrieve the call from hold, simply press its line key.
Note:
If your station doesn’t have line key appearances, pressing HOLD causes an exclusive hold; i.e., the line key remains solidly lit on all other stations with that line key programmed.

Paging
Your ESI phone system can be programmed to allow paging through an overhead paging system and/or paging through some (if page zones have been created) all of the system’s Feature Phone speakers.
Overhead paging
Station number 199 is designated as the OH paging port. If the ESI system has been connected to an overhead paging system, you can page by dialing 1 9 9 and making your announcement after the tones. If you frequently page, program a programmable feature key with 199.
Paging through phones
Press PAGE 0 to page through all of the ESI Feature Phone speakers. Press PAGE and then 1, 2, or 3 to access a programmed paging zone. (See the administrator for a list of page zones.) The Installer may have added an overhead page system to one or more of these page zones.
Note:
Phones in use will not carry a page through their speakers.
To page for pickup of an outside call
To page someone to pick up an outside call:
- Park the call by pressing PARK.
- Verify the line number from the display.
- Page the person and announce the park location for retrieval. For example:
“Sarah, you have a call on Park Two — Sarah, Park Two, please.”

Back to Feature Phone topics page |
Call pickup
From your station, you can answer a call ringing at another station or department* by pressing PICK UP and then either dialing the extension or (if the destination is programmed into one of your keys; see “Programmable feature keys”) pressing the appropriate ringing station key.
During night mode, if a night bell is in use instead of the night auto attendant, press PICK UP 0 to access the ringing outside call.

Back to Feature Phone topics page |
Special keys
FLASH
The FLASH key serves several purposes:
- Getting a fresh dial tone without replacing the handset — When connected to an outside line, press FLASH to automatically disconnect and receive fresh outside dial tone. (See also “RELEASE.”)
- Sending a flash hook signal — If operating behind Centrex (a special service your phone company may offer; see your administrator for additional details) or a PBX, press FLASH to transmit a flash hook signal automatically to either the phone company’s central office or the host PBX. Either may use this signal to provide you with additional features.
- Toggling between calls — If you hear a call waiting tone while on a call, press FLASH to toggle between the two calls.
REDIAL
The REDIAL key allows you to automatically call a stored name and number as shown below:
| To . . . | Press REDIAL . . . |
| Redial the last number called | When your station is idle . . . or . . . After first lifting the handset or pressing SPEAKER |
| Automatically respond to a message | During message playback with Caller ID |
RELEASE
The RELEASE key serves several purposes:
- If pressed when you are connected to a call through the handset, it disconnects the call and gives you internal dial tone.
- If pressed when you’re connected to a call via the speakerphone, it disconnects the call.
- If pressed during call waiting, it drops the current call and automatically connects to the waiting call.

Back to Feature Phone topics page |
Esi-Dex
Esi-Dex (“easy Dex”) is a powerful feature that allows you to access and auto-dial stored names and numbers. You may access names and numbers from three different sources:
| Dex | Source |
| Personal Dex | Names that you have stored for your use (see “Adding names to your Personal Dex”) |
| Station Dex | All station, department and guest mailbox names programmed by the Installer |
| System Dex | All system speed-dial names set up by the administrator |
Auto-dialing using Esi-Dex
While your station is idle (or just after receiving dial tone), repeatedly press ESI-DEX to select the desired Dex:
![Select Dex [1]](/images/LCD_Esi-Dex_trio_1_pug.gif)
![Select Dex [2]](/images/LCD_Esi-Dex_trio_2_pug.gif)
![Select Dex [3]](/images/LCD_Esi-Dex_trio_3_pug.gif)
Note:
The System Dex is not available if the Administrator has programmed no system-wide speed-dial numbers.
Choose the desired name from the selected Dex, using one of the two following methods:
| Press repeatedly . . . | To . . . |
or
(scroll keys) |
Scroll through all names in the list from the beginning or end |
| (A dialpad key) | Scroll through only the names that correspond to the three letters on the key. |
When the desired name and number appears . . .

. . . press ESI-DEX again to dial the number.
Adding names to your Personal Dex
Caller ID method
Whenever a Caller ID name appears on your ESI Feature Phone’s display (while you are talking on an incoming call or during message retrieval) press ESI-DEX to automatically store the name and number in your Personal Dex. The display confirms:

Manual method
While your station is idle, press ESI-DEX until prompted
to ADD-A-NAME, then enter the name and the number as prompted (if needed,
use the PROG/HELP key for assistance):

- To enter each character for the name, press the dial pad key that includes the desired character. The key’s possible character entries will change each time you press the key.
- When the desired character is displayed, press # to
confirm the character. The cursor will move to the next character
position. Use the
/
keys to back up or to insert a space.
Example:
To enter a B, press 2 twice (the possible options to scroll through are A, B, C, and 2). When B appears, press # to confirm and move to the next entry.
- Repeat steps 1–2 until the name is complete. The name may contain up to 15 characters (a space is a character, too).
- Press # again when finished entering the name.
- Now, enter the number — including, if necessary, the line access code
9 (or 8 or 71–76 [7 on IVX 20 Plus]).
Note:
To insert a two-second pause, press CONF. To insert a flash (F), press FLASH. For a star (∗) tone, press REDIAL. For a pound (#) tone, press TRANSFER.
- Press # to confirm the entry.
Deleting names from your Personal Dex
Select the name to delete (using the procedure described in “Auto-dialing using Esi-Dex”) and press * (or HOLD) to delete.
Using Esi-Dex: An example
Let’s say you’re on a call with the XYZ Company — XYZ COMPANY
appears on your display — and you wish to save the name and number for future use.
Just press ESI-DEX. Your display will confirm that the
information has been stored. Now, to call the XYZ Company in the future:
- Press Esi-Dex until you see
PERSONAL DEXon the display.

- Press the 9 key (corresponding to WXY). The display
will show the first stored name that starts with W, X or Y.

- Continue to press 9 until
XYZ COMPANYappears in the display.

- Press ESI-DEX again. This dials the number for the XYZ Company.
Important:
The number dialed (if stored from a Caller ID) will be the number for the actual line used by the caller, and may be different than the caller’s listed number. Additionally, some local calls may not be auto-dialed correctly, depending on the limitations of your area’s local dialing plan. You may wish to create a manual listing for these. Consult your administrator if you need further assistance.
System speed-dialing with Esi-Dex
If your administrator has programmed system speed-dial numbers, you can access one of these numbers either via Esi-Dex, as explained in the foregoing discussion, or auto-dial it by dialing its corresponding three-digit access number (in the range 600–699).
Example:
If an out-of-town factory location has been programmed as system speed-dial access number 605, you can lift the handset, receive internal dial tone, dial 6 0 5, and this will automatically dial the factory’s number. You may also program 605 (in this example) as a programmable feature key.

Back to Feature Phone topics page |
Message monitor mode (live call screening)
Message monitor mode, also known as live call screening, lets you hear a caller leaving a message in your mailbox — just as with your home answering machine. You turn this feature on or off as part of user programming (PROG/HELP 3 6), or you may program a feature key for this purpose (see “Message monitor key (Code 568)”). While you hear the caller through your speaker, you have the following options:
| Option | Result |
| Lift the handset | You intercept the call |
| Do nothing | The system records the message to your mailbox for your later retrieval |
| Press MUTE/DND | Temporarily mutes your speaker (the system continues to record the message to your mailbox) |
Note:
During monitor mode, you will hear a call ring, then subdued ringing while the caller is hearing your personal greeting, then the caller’s message. You can intercept the call at any time.
Back to top |
Back to Feature Phone topics page |
Personal greeting reminder
If you frequently change your personal greeting, use this option; it sets your station to remind you of your current greeting. The first time you use your phone after it has been idle (for the period you set in this function), the system automatically plays your current greeting (and gives you the option to change it). The range is 0 (no reminder) to 500 hours. To set this, press PROG/HELP 3 2.
Example:
If you change your personal greeting only when out of town for a few days, set the reminder interval to 60 hours; you’ll be reminded if your phone has not been used for three days. Set it for 36 hours and you will be reminded every Monday morning or if you are away for a couple of days. If you change your greeting several times a day, set the reminder for about three hours.
Back to top |
Back to Feature Phone topics page |
Headset operation
You can use your phone with a headset connected to the handset jack. You must have a headset key programmed as one of your programmable feature keys (see “Other feature keys”) to be used to connect or disconnect from a call. (See also “RELEASE.”) The key will blink green when a call is ringing and glow green when connected. You turn Headset Mode on or off as part of user programming (PROG/HELP 3 3).
Back to top |
Back to Feature Phone topics page |
Outside dial tone preference
If you make mostly outside calls, you may find this setting helpful. It tells your station to connect automatically to an available outside line; i.e., you don’t have to dial 9 (or 8 or 71–76 [7 on IVX 20 Plus]) before the phone number. Therefore, when you lift the handset or press SPEAKER, you will immediately receive an outside dial tone from the highest-numbered line available to you.*
Note:
To place an internal call while in this mode, press the appropriate station key or (a.) press TRANSFER to switch to internal dial tone and (b.) then dial the extension number.
Back to top |
Back to Feature Phone topics page |
Line keys
If some of your programmable feature keys have been programmed as line keys (or you can program line keys using PROG/HELP 2), press an unlit key to access the line. An outside call transferred to your station can be answered by simply lifting the handset or pressing SPEAKER. You do not have to press the line key. The LED indications for the line keys are:
| LED | Line status |
Glowing red![]() |
In use |
Green![]() |
Connected to your station |
Blinking red![]() |
Ringing at another station |
Blinking green![]() |
Ringing at your station |
Slowly blinking red![]() |
Parked by another station |
Slowly blinking green![]() |
Held or parked by you |
Note:
Dialing 9 (or 8 or 71–76 [7 on IVX 20 Plus]) to be assigned a line automatically is always available.
Private line
If a private line has been assigned to your station, you must have a line key programmed in order to access it.
Back to top |
Back to Feature Phone topics page |
Optional features
The following optional features may be accessible from your station. See the administrator for details. In many of the cases you can dial the appropriate feature code (one that starts with 5), to activate or use the feature. In some instances, you must use a programmable feature key to serve as an on/off key for the feature.
Manual day/night mode (Code 560)
The system’s main greeting can be manually changed using a programmable
feature key. Each time the key is pressed, the display switches among the following:
DAY, NIGHT, HDAY (holiday) or
AUTO (AUTO indicates that the system will follow
the day/night mode tables programmed by the Installer).
Tip:
Placing the system in Auto, then deleting the key’s programming, will keep the system from being taken out of this mode.
Note:
The administrator can also change the mode and/or re-record the holiday greeting remotely to handle unexpected closings, such as for inclement weather.
Service observing (Code 561)
(Not available on IVX 20 Plus.) Your administrator may assign service observing capability to those users who need to monitor others’ calls silently (e.g., in order to aid in quality assurance of call activity).
Press the assigned programmable feature key (or dial code 5 6 1), followed by an extension number or station key, to begin service observing. To discontinue observing, press the station key again or hang up. While you observe another station’s incoming call, your display shows to whom that station is connected and how long the call has lasted.
Note:
The administrator must authorize service observing for your station and the Installer must program the list of allowed extensions.
Headset key (Code 564)
This key provides for easy connecting to/disconnecting from calls when operating in headset mode (see “Headset operation”). Press the key to receive dial tone or to answer a ringing call. Press the key again or press RELEASE to disconnect from the call.
Call forward key (Code 565 or 565xxx)
If you frequently call- forward your phone (see “Call forwarding”), you can program a programmable feature key as a call forwarding key to automatically turn forwarding on and off. If you always forward to the same extension, you can program a key with both 5 6 5 and the extension number.
Message monitor key (Code 568)
(Works with IVX 128 Plus, IP 200 and IP 40.) Easily toggle the message monitor mode on or off with this key. (Otherwise, you can perform the toggle by pressing PROG/HELP 3 6 and following the prompts.)
Background announce key (Code 569)
During call waiting, you can also make a brief, private background announcement to the station’s earpiece (if the station user has enabled the background announce feature). Press the key to talk and release when finished.
Personal greeting key (Codes 571–573)
These keys will provide for easy activation of one or more of your personal greetings. The key’s LED will be green for the associated personal greeting that’s active. These keys can be used in place of or in conjunction with manual activation of the greetings in programming mode.
Note:
For ACD key programming [not available on IVX 20 Plus], see “ACD agent operation.”)
Missed Call key (Code 574)
Note:
This works only if you are receiving Caller ID service from your provider. Consult your Administrator if needed.
(Works with IVX 128 Plus, IP 200 and IP 40.) A programmable feature key
with this code will flash whenever you have a missed call — i.e.,
both (a.) you don’t answer a call to your station; and (b.) the caller
doesn’t leave a message in your voice mailbox. When the key is flashing,
press it to see the stored Caller ID record for the most recent missed call.
Use the scroll keys (
/
) to
view records for other missed calls; your ESI phone system will store each user’s
Caller ID records for up to 10 missed calls.
Note:
When your station receives its 11th missed call, this will delete the oldest missed call.
Additionally, while a record is on the display, you may do the following:
- To dial the caller displayed, press REDIAL.
- To view the telephone number (rather than the name), press 2.
- To delete a record, press 7 while the record is on the display.
- To store the record in your Personal Dex, press ESI-DEX.
Note:
If your station is forwarded to another extension, any calls will be considered answered and the Missed Call key will not flash. However, if that other extension has a Missed Call key programmed, that key will flash (under conditions (a.) and (b.), as described above) even if the call is actually forwarded from your extension.
Virtual Answer keys (Codes 575, 576)
Note:
This works only if call waiting is enabled for your station. Consult your system administrator if needed.
(Works with IVX 128 Plus, IP 200 and IP 40.) You can program a Virtual Answer key to play a greeting to a caller when your extension is busy and route the caller to a desired destination by pressing this key. Program a programmable function key with either 5 7 5 or 5 7 6. Prompts will instruct you in how to record the greeting and program the caller’s destination.
The destination can be either the default call waiting or another station; the system takes the caller there after playing the recorded greeting. With call waiting, the system places the caller on hold as call waiting (“camping on”) for your station; if the caller can’t wait, he/she may (a.) press 1 to reach your voice mail, (b.) enter another extension, or (c.) press 0 to reach the Operator. With another station selected, the call is forwarded to the station.
To record the greeting from an idle phone:
- Press the chosen programmable function key; then press RECORD.
- Follow the prompts to record the greeting and program the destination.
Sample greetings for call waiting keys:
“Hello. This is Harvey. I’m currently on another line, but I’d really like to speak to you. Please hold and I’ll be with you shortly. However, if you don’t wish to wait on hold, press 1 to leave me a voice message. You may also either dial another extension or press 0 to reach the Operator.”
“Hello. This is Bill. I’m currently on another line, but I’ve been notified of your call. I am sending your call to our Sales Department administrator for more immediate assistance. Please remain on the line as your call is being transferred. Thank you.”
QuickPage (Code 577)
(Works with IVX 128 Plus, IP 200 and IP 40.) Normally used by an operator, this key lets you quickly park and page a station user. After programming a key as a QuickPage key, you can — while on an outside phone call — press the key, then enter a station number (or press a programmable feature key programmed for an extension) and the system will automatically page the person*, then forward the call to the person’s extension (or, if there is no answer, the person’s voice mailbox).
