Parameter
–
sip lineN call waiting
(N is a line number from 1 to 9)
Configuration Files
aastra.cfg, <model>.cfg, <mac>.cfg
Description
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.
