Route header problem

[Alex Rendour]

Hello,
We have a problem with route on header.

I  receive an ack from X.X.X.X  (asterisk) on Y.Y.Y.Y (kamailio 1.5.3).
 Y.Y.Y.Y relay ACK to  Z.Z.Z.Z

Y.Y.Y.Y this route from X.X.X.X:
<sip:Y.Y.Y.Y;lr=on;ftag=as7e58db45>,<sip:11dc0d7918b56374@...;lr>

And forward as the same to Z.Z.Z.Z.

The route header must be :
<sip:11dc0d7918b56374@...;lr>

I think  my kamailio must delete  the  first part of  the route header,
like  this explaination:

Could you help me?

Regards,

Are you doing "loose_route()" for this ACK?

When i receive the ack from X.X.X., i just relay to Z.Z.Z.Z with this:

if(!is_method("INVITE")){
                if(lookup("location")){
                        t_relay();exit;
                }

Wrong. ACK for 200 (that containing Route header) is a new in-dialog
transaction so it must be handled by "loose_route" section. Please
check the default config file of Kamailio.
