Hi I want to implement one way audio stream through Freeswitch(Default Media Mode). SoftClient1 -----------> Freeswitch --------------->SofClient2 (will speak only) (will listen only) For this i have set *origination_audio_mode=sendonly* in the dialplan at the time of bridge.After setting this parameter in freeswitch forward the invite to b-leg with sendonly media attribute and hence SoftClient2 replies with recvonly in 200OK.The packets flow like below: SoftClient1 --------------(sendrecv)----------------> Freeswitch -------------(sendonly)--------------> SoftClien2 <-------------(sendrecv)---------------- (origination_audio_mode=sendonly) <------------(recvonly)-------------- *Now the problem is I am not not able to hear any sound at SoftClient2.* When i checked the wireshark capture at Freeswitch i found that Freeswitch is sending RTP packets on Private IP of SoftClient2 and not the Public IP. If i remove this parameter,Freeswitch starts sending RTP to the public IP and i am able to hear sound both way. Can i get some help on this? *Why the Freeswitch server is sending the RTP packets on Private IP with origination_audio_mode=sendonly?* -- *With Warm Regards:* *Saurabh Kumar Verma*
