could be an issue of the local gateway. most NAT devices explicitly block "hairpinning", which is happening in your case.

Hello Rafael,
This is an issue I'm having at the moment as well, where two UA's are behind the same nat. SIP obviously works fine, I can ring one UA from the other (one UA a Grandstream Budgetone 100 and the other the X-Lite softphone from Counterpath). Audio doesn't work. Did you get this working with forcing rtpproxy?

I am using avpops to enable SER to see if the UAs are located behind the same address and now I need to let the UAs speak directly to each other (without force rtpproxy), please someone see my configuration below and send some advice.

----. if (!lookup("location")) { log(1,"unable to locate user \n"); # handle user which was not found route(4); break; };
### Test if UAS are in the same NAT: # get the host part of the final uri (IP part) # and store it in AVP ID 13 avp_write("$ruri/domain", "i:13"); if (avp_check("i:13","eq/$src_ip/i")) { log(1, "source IP is the same as destination IP\n"); route(3); break; }; avp_delete("i:13/g"); . . # -------------- Same NAT Call Routing (no force rtpproxy) ----
route[3]{ log(1," route[3]: UAs are in the same nat, NO force_rtp_proxy ");
### Do something!!!!
