Hello all,

 

I have a script working with openser1.2.1 and I try to move them to kamailio 3.2.1

 

I have actually an issue with the loose_route() function at least for ACK message.

 

When I get the ACK the loose_route function is changing the URI with the value of the route header of the ACK message .

The problem is that this value is the local proxy himself so  the t_relay() function send the ACK on the loopback interface.

 

Any Idea ?

 

Regards

Laurent
