Hi everyone,
I have asterisk farm and kamailio which located front of asterisks farm as a proxy.
When someone send a invite from outside to my kamailio (without record route), i forward it to my Asterisk farm. Then My one of Asterisk reply it as 200 ok. Then my kamailio forward this 200 ok to remote side with record route. But in my 200 ok message, contact header contains my Asterisk IP address. That is why remote side tries to send ACK to Asterisk.
How to rewrite my contact header as my kamailio (SBC) address ?
Actually I tried fixed nated contact and advertise ip but I couldn't make it worked. I am really new on that. Kamailio cfg file is attached.
Please help!

It is wrong if your remote party ignores record-route. If it does not support work with RR/Route headers it at least should interrupt transaction on the first reply that contains RR.
However There are a couple of ways to make kamailio work as SBC: - topos module - Rewrite contact header manually ( by removing old and inserting new one)
NAT helper functions will not help you as they are check source address of the message and fix contact based on this part. So it will not Rewrite Contact address on SBC address. It will Rewrite contact if it does not match with the source address of the message.

Definitely you're right but remote site can't solve their problem, that's why I am trying to solve that.
Btw, I ve achieved to hide the IP address of contact header thanks to topoh. But once kamailio got ack, it doesn't know where to send, that means it can't decode the key. (it is my opinion)
When I searched it, I saw that I should use topos & redis to store. But no module on Kamailio 4.3.x. it might be released on 5.x and above..
Is there any recommendation for decoding properly?

You always can realize all those things by your own by saving information in additional params in contact and ruri or locally in the db you are using with kamailio or in the hash. It's required to write more config aka codebut still a way.

i Don’t see any reference to redis in https://kamailio.org/docs/modules/4.3.x/modules/topoh.html it should work without redis.
Can you please share the log when kamailio receives the ACK?
