Hello,

it is not clear for me if there are two contact records in the location table. If there is only one, then you do something in the config to create the second branch. Kamailio should create only one after lookup("location"). Maybe you can share relevant parts of the config to be able to help you more.

Cheers,
Daniel

Hi All,

Kamailio send 2 INVITE(lookup rewrite r-uri and append branch) request for Client behind NAT.
Due to this reason for one request,Client respond with 486 Busy here. we only want to send  1 INVITE request.

Following are the AOR for client at kamailio.if field(ip port) in CONTACT and RECEIVED differ then kamailio send 2 INVITE request.


FOLLOWING INVITE HAS BEEN GENERATED AFTER LOOKUP FUNCTION(one from contact and one from Received field).

INVITE:sip:123@192.168.230.124:45672
INVITE:sip:123@204.192.206.208:45672

I want only ONE INVITE request to be generated.Please suggest how do solve this issue or if there is any config change or any code change required to achieve this?
