[OpenSIPS-Users] topology_hiding

[Kirill Galinurov]

Hi. All we try topology hiding module.
We have opensips 2.3/2 like sbc with to interfaces.
And ip addresses are X.X.X.X and y.y.y.y.
We have to softswitch with ip addreses z.z.z.1 and z.z.z.2
Also we loadbalancing calls between softswitch .
My config
if(is_method("INVITE"))  {
           create_dialog();
           topology_hiding();

In invite on softswitch i see

CSeq: 102 INVITE

Where CC is client ip. I thithk it must be opensips ip adress
10.240.250.121:5126
What is wrong?
