[SR-Users] Rewrite From domain

[Gonzalo Gasca Meza]

Hi Daniel,

I added xlog and $mb here is the debug:

I still cant figure out how to overwrite the From field.

http://pastebin.com/vMruA0tP

Call flow:

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


# Manage outgoing branches

branch_route[MANAGE_BRANCH] {


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

           xlog("L_DBG","$mb \n| Masking call from: $fu");

           $fd = "pstn.parzee.io";

           $fu = "sip:" + $fU + "@pstn.parzee.io";

        }

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

        xlog("L_DBG","$mb \n| New branch \n");

        route(NATMANAGE);

}
