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. I can mail any settings if anybody asks. Thanks in advance.
