[OpenSIPS-Users] Opensips 2.2.2 and top hiding

[Denis]

Hello!

I try to make top hiding using topology_hiding module.
In attachment you can find a log of unsuccessful call.

Scheme of the call

SIP UA (2.2.2.2) -> Opensips with top hiding (1.1.1.1) -> another Opensis proxy (3.3.3.3) - > PSTN GW (4.4.4.4) -> PSTN.

As i understand,  the problem is that Opensips proxy cannot send ACK (on 200 OK) to PSTN GW because RURI and Route header has similar IP, namely 3.3.3.3.

I am using "topology_hiding("C");" function for top hiding.

The call log was gathered from 1.1.1.1

Thank you for any help.

P.S. On 1.1.1.1 i also try to make load balancing.
