Thank you for your reply.
I tried the config file shared by Alex below , but I noticed that kamailio is not dealing with CANCEL requests. the scenario in my case is that I’m using Kamailio behind a switch to alter some packets (precisely 183 packets) , so I need to forward all packets coming from my customer to the switch , which will deal with it (send it to appropriate supplier). So what I need is the config file that will forward all requests coming to Kamailio from my customer , to forward them to my switch , then reply back to customer the reply coming from the switch. 9after altering 183 packet to 180) , handling the in-dialog invites sent by my switch , which needs to be sent to the customer by kamailio.

Default kamailio.cfg has almost identical part for this purpose. Main idea is that an initial request (non in-dialog) hasn't To tag already. It appears only when your request "hits" remote side (called or callee, as you wish) and goes back to you. Simplified, but I hope you got an idea :) -- sent from myMail for Android вторник, 17 июля 2018г., 17:16 +03:00 от Ali Taher ata...@vanrise.com <mailto:ata...@vanrise.com> : Hi Alex, Thank you for your reply. Does below config forward all sip requests coming from the customer to the supplier , and relay sip replies back to customer ? Where re-invite packets are handled in the below config file?
