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.
Thanks

ReInvites like all in-dialog requests are processed in has_totag()/loose_route part. 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 :)

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?
Thank you Ali Taher

Can you please send me a simplified config that suit my case ?
Try this for a main request route:
---
route { if(!mf_process_maxfwd_header("10")) { sl_send_reply("483", "Too Many Hops"); exit; }
# Maybe some sanity_check() here.
if(has_totag()) { if(loose_route()) { if(!t_relay()) sl_reply_error();
exit; } else { if(is_method("ACK")) { if(t_check_trans()) t_relay(); } else sl_send_reply("403", "Forbidden"); }
exit; }
# CANCELs / branches.
if(is_method("CANCEL")) { if(!t_relay_cancel()) { sl_send_reply("500", "Server Internal Error"); exit; }
exit; }
t_check_trans();
if(is_method("OPTIONS")) { sl_send_reply("200", "OK"); exit; }
else if(is_method("INVITE")) { # Route your calls.
exit; }
sl_send_reply("403", "Method unsupported"); exit; }
