Parameter – 
sip lineN call waiting

(N is a line number from 1 to 9)

Configuration Files
aastra.cfg, <model>.cfg, <mac>.cfg

Allows you to enable or disable Call Waiting on the IP phone on a per line basis.

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 sec-
ond 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 con-
figured 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 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.
