<div dir="ltr">Hi,<div><br></div><div>In one of the client servers, an old version of FreeSWITCH(FreeSWITCH Version 1.0.head) and a fairly new version of FreeTDM(wanpipe-3.5.28) is being used. </div><div><br></div><div>Recently a new problem is being observed, where when an incoming call via Sangoma E1 card is redirected to a ring group which rings 3 internal SNOM extensions, and the call is answered on one of them, audio is heard by the caller, but nothing is heard on the callee end. I have captrued the network trace, and I see that there is exchange of RTP packets between the ports specified in the SIP trace (as well as the AUDIO RTP log of freeswitch)</div>
<div><br></div><div>Any pointers on how to debug this issue further?</div><div><br></div><div>Thanks!</div></div>
