Hi All,<br>
<br>
Any help is welcomed & thanks in advance<br>
<br>
<u>Scenario : </u><br>
Sip Phone(machine1) ---> SS7 Link --> Sip Phone(machine2)<br>
<br>
<u>Problem : </u><br>
The call pass through, the destination extensions rings. when I Pick
Up i continue to hear the ringing in both extensions and there is no
voice.<br>
<br>
Within Asterisk Logs i have the next warning message :<br>
<br>
<pre> NOTICE[28699]: channel.c:2591 __ast_read: Dropping incompatible voice frame on SS7/siuc/30 of format ulaw since our native format has changed to 0x8 (alaw)</pre>
<br>
I tryed allow=all on sip.conf & iax.conf but the result is the
same<br>
<br>
