Ever since we upgraded to asterisk 11 we have had audio problems with<br>
our cisco 7940 phones.<br>
<br>
The problems manifest themselves by the conversation turning "robotic"<br>
or into silence (to the extent our agents are saying "hello? hello?"<br>
and the customer is saying "I hear you just fine"<br>
<br>
We had to change pedantic=no in sip.conf to allow the phones to register<br>
<br>
We are assuming that it is the phone<=>asterisk combination because<br>
<br>
a) the call recordings of the conversation are perfect (no noise on<br>
the line, conversation is clear) but it is apparent that the agent<br>
cannot hear the customer sometimes (Hello?)<br>
<br>
b) we have replaced the cables and switches between the phones and the pbx<br>
<br>
c) we don't have the same problem with Aastra 9133i or Polycom 331 phones<br>
<br>
Are there any settings in sip.conf that may help this , or a<br>
particular firmware ? Are there any known audio problems with cisco<br>
7940 and asterisk 11 ?<br>
<br>
Many thanks<br>
