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);

}

Hello,

for the case when it doesn't work, do you see the xlog message printed?

Cheers,
Daniel

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:

Works: http://pastebin.com/k0jZ3aDE

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

Hello,

as alternative to assigning to $fd, you can use uac_replace_from() exported by uac module.

The best place to do updates to headers for outgoing traffic is in a branch_route block.

Cheers,

Hi all,

I'm using Kamailio to forward calls between 2 Service Providers and I need to rewrite the From header "domain" URI.

Example:

From: "+18888888888" <sip:+18888888888@sip.sp1.com> to

From: "+18888888888" <sip:+18888888888@sip.sp2.com> 

Call flow:

Phone A --- > SP1 ---> sip ----> (kamailio) SP2 --(LOCATION)-> Phone B

When Phone A calls SP2 PhoneB, it contains original sip domain from sp1. (sip.sp1.com) hence user in SP2 can see call comes from SP1. I would like to rewrite the From domain field in this conditions:

a) Calls comes from "sip.sp1.com" AND

b) Call is being routed to PhoneB. 

Right now Im using the following code to find user and send call to B.

#!ifdef WITH_ALIASDB

        # search in DB-based aliases

        xlog("L_INFO","alias_db_lookup: Call received. $rU\n"); 

        if(alias_db_lookup("dbaliases")) {

                route(SIPOUT);

        }

#!endif


I found this in documentation:

$fd - From URI domain

if($hdr(From)=~"sip.sp1\.com") {
 ...
}

But not sure where is the best place to overwrite the From URI domain header.

Thanks
