[OpenSER-Users] Not adding record-route for ack

[Robert Dyck]

The route is determined by the INVITE as it makes it's way from the UAC to UAS 
while collecting Record-Route's as it goes. The UAS then forwards the 
Record-Route list back to the UAC in the 200 OK. Both ends are now aware of 
the route set which will not be altered in this dialogue. Any further 
messages in this dialogue must follow the route set. If in-dialogue messages 
contain Record_Route the Record-Route must be ignored.

The short answer is that ACK may contain Record_Route but it will be ignored.
