Hello, Is there a way to establish a call with one-way audio on a call from the start? I'm currently sending a request with the following SDP - (note a=sendonly): v=0 o=Larry 2890844526 2890844526 IN IP4 127.0.0.1 s= My Session c=IN IP4 172.22.112.1 t=0 0 m=audio 49170 RTP/AVP 0 8 a=sendonly a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 FreeSWITCH is sending back the right response (note the a=recvonly): v=0 o=FreeSWITCH 1519171720 1519171721 IN IP4 172.17.0.2 s=FreeSWITCH c=IN IP4 172.17.0.2 t=0 0 m=audio 21768 RTP/AVP 0 101 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=recvonly a=ptime:20 But I'm still receiving audio from FreeSWITCH. It is only after I resend the SDP via a reinvite that the audio stops being sent from FreeSWITCH. Larry
