[SR-Users] Rewrite From domain

[Gonzalo Gasca Meza]

Hi Daniel,

Thanks for the advise, I'm using the following configuration,

# Manage outgoing branches

branch_route[MANAGE_BRANCH] {


        if($fd=~"sip\.sp1\.com") {

           xlog("L_INFO","|Masking SP1 call from: $fu");

           $fd = "pstn.parzee.io";

        }

        xdbg("new branch [$T_branch_idx] to: $ru from: $fu\n");

        route(NATMANAGE);

}

I have two scenarios which are very similar:

1) PSTN call -> SP1 --> VXML -> Call forward to --> 5061 Kamailio --> DNS
resolution -> Remote client, I do see pstn.parzee.io WORKS

2)  SP1 -> SIP call --> 5061 Kamailio --> DNS resolution -> Remote client,
I dont see pstn.parzee.io I see sip.sp1.com DOESNT WORK

I have attached the traces, destination is the same, all calls are SIP TLS
in both call legs, any suggestion tu turn on higher debug level to see SIP
messages.

Traces:

Doesnt work: http://pastebin.com/p19rwcrn
