Try here https://www.kamailio.org/docs/modules/5.6.x/modules/tm.html#tm.e.local-requ… However I would doubt first do I do something right by adding contact to ACK message wichbasicaly confirmation of the final transaction and contact here is meaningless.

I made simple tests and it seems that this is a kamailio-TM-internal message being sent, not being processed by the cfg file. If this is simple enough and deterministic, you may consider using the corex module to edit the message as it's being sent "on the wire". I can't think of any other solution. https://kamailio.org/docs/modules/5.6.x/modules/corex.html#corex.evr.networ… You may be able to write some code that manipulates the message to manually add the Contact header. Maybe even the append_hf function may work here, but it seems unlikely. James On Mon, 8 May 2023 at 12:28, mohsen khashei <mkhashei(a)gmail.com> wrote:

Hello, why you actually need to add the Contact header to the ACK? According to the RFC 3261 is should be an optional header to that message.

For a failure message there can not be any Contact header. Never. There’s no one to contact! /O

You may be able to write some code that manipulates the message to

manually add the Contact header. Maybe even the append_hf function may work here, but it seems unlikely.
