I have been running for quite some time an Asterisk 1.8.xx callcenter with CANTV MFC-R2 in Venezuela.<br>
<br>
Callcenter agents have been reporting for a long time that some inbound calls have no audio. We debug the R2 signalling from CANTV side and we found that when call is answered, some times Asterisk sends a CLEAR BACK signal to CANTV and when operator answer, they don’t see audio as the call is already gone.<br></blockquote><div><br></div>You need debug logs from the asterisk side to see why is clear back sent.<br class=""><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><p style="margin:0px">-</p><p style="margin:0px">Moy</p></div></div></div></div></div></div>
