[Freeswitch-users] Internal IP showing in SDP

Hi Brian,
it seems that this was not the issue.
Some more details:
We have an opensips server using the load_balancer module to route the
calls to the freeswitch box.
(https://wiki.freeswitch.org/wiki/Enterprise_deployment_OpenSIPS)
When I route the calls directly to the freeswitch's external IP, the
calls connect fine and have audio.
However when I route the calls to the opensips server first, the call
will connect but without audio.
The strange thing is Opensips uses Freeswitch's internal address (from
the load_balancer table) to forward the INVITE packet, yet when the ACK
packet comes in from the provider opensips tries to forward it to the FS
external IP address rather than the internal IP.
I understand this is probably more an opensips question, so will
understand if I should post this to their mailing list, but any tips
would be appreciated.
thanks
Matt
