<div>Hi,</div>
<div>I remember a similar situation where agents using SIP softphones with incorrect configured Codec caused similar results, droping the call when answered.</div>
<div><br>
</div>
<div>A full debug log from asterisk will help find the cause as pointed by Moy as this can be related to a larger scope in asterisk.</div>

Hi everybody, hope you are doing very well.<br>
<br>
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>

</div>
You need debug logs from the asterisk side to see why is clear back sent.<br class="">
