Call waiting
To enable call waiting for your station, press ∗ xxx 5 3, where xxx represents your extension number. Then, if someone calls you while you’re already on a call, you’ll hear a tone in your earpiece. FLASH to toggle between the original call and the call waiting. To drop either call, hang up while connected to the call to be dropped. When your phone rings, lift the handset and you will be reconnected to the other caller.
Note:
The ESI phone system doesn’t support call-waiting Caller ID on analog stations. If you’re unsure which ESI system you have, consult your Installer or System Administrator.
