Hello, Below is the call flow i am trying to achieve and getting 'no audio' while call established, i can hear the ring back tone though client registration through public ip [SERVER A], nat rule to route the request to local ip [SERVER A's CONTAINER A1] --> getting the request to local ip through Profile1; this is a freeswitch server using mod_distributor to balance the load between two freeswitch servers [SERVER A's CONTAINER A1]--> getting the request to local ip through Profile2; this is a freeswitch server1 [SERVER B's CONTAINER B1] --> sending back the response to [SERVER A's CONTAINER A1] using Profile3, nat rule is there to route the traffic to public ip [SERVER A]/to the caller sip signaling works as it should having issues with media signaling though, 'no audio' on call while call get established, let me share some params value of respective profiles regarding media on Profile1, inbound-bypass-media = false inbound-proxy-media = true on Profile2, inbound-bypass-media = true inbound-proxy-media = true on Profile3, inbound-bypass-media = true inbound-proxy-media = false Below is the file containing sip logs from [SERVER A's CONTAINER A1] http://pastebin.com/zpzT81dL Below is the file containing sip logs from [SERVER B's CONTAINER B1] http://pastebin.com/aMAQB45i caller's ip -> 182.72.122.102 public ip to register -> 51.21.91.151 [SERVER A's CONTAINER A1 eth0] -> 10.93.53.126 [SERVER A's CONTAINER A1 eth1] -> 172.16.1.2 [SERVER B's CONTAINER B1 eth1] -> 172.16.3.2 carrier/provider/gateway/termination ip -> 216.56.6.6 (Above are not the real ips, they are changed;)) What am i missig here?
