Hi,
I use Kamailio for basic call setup with one exception where it has to route
call to another server by seeing the domain name in the Request URI.
If the Request uri in the received INVITE message looks like
"sip12345@video-conf", then it should route the INVITE request to the
video-conf server by resolving the domain name. I changed the config file
kamailio.cfg as given below.
route[SIPOUT] {
if (!uri==myself)
{
append_hf("P-hint: outbound\r\n");
# AKS: call routing
if (uri=~".*@video-conf")
{
rewritehost("video-conf");
}
# AKS
route(RELAY);
}
}
It resolves the domain name and routes the INVITE message to the resolved IP
address. However it uses the domain name in the Request line and To header and
I need to replace domain with the resolved IP address in the Request URI and To
header.
Now Request URI and To header look like "INVITE sip:12345@video-conf" and "To:
<sip:12345:video-conf>" respectively and I need them as "INVITE
sip:12345@video-conf" and "To: <sip:12345:video-conf>".
I don't have any knowledge in tweaking kamailio. I tried some tricks like the
following by going through documents and pervious emails in the forum. But it
didn't work. Some of them have spoken about avp and pseudo variables. But I am
getting confused as I have just begun using Kamailio and it is vast.
# $ru = "sip:" + $rU + "@" + to_ip;
I will appreciate if you could help me or guide me in right direction.
Thanks,
Ajay
