call waiting

Call Waiting
(in Web UI)

Basic Settings->Preferences->General

aastra.cfg, <mac>.cfg

Allows you to enable or disable Call Waiting on the IP phone. 

If you enable call waiting (default), the user has the option of accepting a 
second call while currently on the first call. If you disable call waiting, and 
a user is currently on a call, a second incoming call is automatically 
rejected by the phone with a busy message.

If you disable call waiting on the phone, and the user is on a call, any 
further incoming calls will receive busy unless “Call Forward Busy” or “Call 
Forward No Answer and Busy” is configured on the phone. It will then 
forward the call according to the rule configured. The phone can only:
•

-transfer the currently active call 

or 

•

accept transferred calls if there is no active calls.

If call waiting is disabled:
•

on the 6757i CT base, and the handset is currently on a call, all 
additional incoming calls are rejected on the handset.

•

intercom calls are treated as regular incoming calls and are rejected.

•

pre-dialing with live dial pad disabled still accepts incoming calls.

•

the “Incoming Call Cancels Dialing” parameter is ignored because the 
incoming call is automatically rejected.

•

the Missed Calls List does not get updated with details of calls.

•

the Blind Transfer feature on the phone may not work if two calls are 
made to the phone at one time.
