Hi Daniel,

Yes I agree with you that kamailio is not involved in the rtp handling and forwarding but RTP Proxy does this. So I have mentioned that when my call is established then my RTP passes through the RTPProxy. The issue is that RTP is coming proper at UAC Side so no Voice Problem but may be RTP is not coming good at Phone Side that is why voice is bad at Phone SIde.

Please see again my network.

SIP UAC--------->Kamailio+RTPProxy------>SIP Server------->Phone

And Kamailio and RTPProxy are on same machine and load is not high only one call is enough to produce this issue. It seems that this issue is with RTPProxy. Please anyone can provide me some settings or inputs on this issue. I can provide more information if required.

Thanks and Regards Varun

Hello,

kamailio is not involved in the rtp handling/forwarding. So either is a bad connection somewhere in the path or an issue in the client sides. Can you try with different phones?

Cheers, Daniel

HI All/ Daniel, We are using the Kamailio+ RTPProxy as a SIP and RTP Proxy to call the Phones. Our setup is like below: SIP UAC--------->Kamailio+RTPProxy------>SIP Server------->Phone Now when we call from UAC to Phone then voice is coming good at the UAC side. But we receive the bad voice at the Phone side the Voice is breaking and hardly audible. Can anybody faced this problem. Please suggest me any solution if any.
