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@Z.Z.Z.Z;lr

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

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

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

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.

OK, thanks loose_route solve my problem.
