[Freeswitch-users] Freeswitch is not receiving audio unless and until send RTP to other end

Hi, Recently I have found the following scenario, Freeswitch is not receiving audio unless and until we send RTP(audio) to other end. I have taken both recording and pcap for the call which is not having outgoing audio. Surprisingly, there is a incoming audio in pcap but not in recording. There is no NAT on machine. Is this any kind of known bug ? -- Thanks & Regards, Naveen Tamanam
