Hi,
I see when you send an ACK for an incoming 200, in Route Header  the stack 
puts:

          - Request URI = Contact received in 200 response
          - Route = Record-Route received in 200 response + Contact received 
in 200 response

Is it necessary to add the Contact in the Route?

It causes if Contact header received in 200 response does not contain ';lr' 
parameter, when the stack sends a BYE, it puts:

          - Route = Record-Route received in 200 response + Contact received 
in 200 response +      Contact received in 200 response


Thanks in advance,
Fran.
