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,
Daniel

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 <(888)%20888-8888>"
<sip:+18888888888@sip.sp1.com> to
From: "+18888888888 <(888)%20888-8888>"
<sip:+18888888888@*sip.sp2.com
<http://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
