Our enterprise customer was using our AR1220 as a route, and enable the PBX service and Nat feature of AR at the same time. Customer hope the sip terminal (TE desktop and TE mobile) could register to AR1220 and could communicate each other.
A can’t make a voice call to C (SIP signaling doesn’t work properly) but C can make voice call to A and the connection build normally, but C could’t hear A’s voice, A could hear C’s voice.
disable AR's sip alg, just enable the SBC feature in AR as following.
