[OpenSIPS-Users] Opensips Multi instance issue on SIP TLS

Tue Apr 12 13:54:13 CEST 2016

Hi

Solved the issue.  Actually what it was doing the location table is storing
the ip and port of the server where register request lands in socket field
so when B-Party register request lands on different server it saves the ip
and port of that server in location table . what I was doing in my code on
invite request i was calling the lookup() function of registrar.so module
to check if the B-Party is registered. It is also fetching the socket
information through where opensips has to relay the invite request to
B-Party. So in my case it was reading the wrong information of socket due
to which this error was occurring because it cannot find the socket through
which invite has to relay to B-Party
What I did I just simply forcefully relayed the invite request to B-Party
through that server where invite request lands by calling the
force_send_socket(udp:1.2.3.4:5060) right below the lookup() function

Thank You Benjamin and Gohar Ahmed for your assistance

regards
Feroze
