Daniel ,

     dialog timeout happen only for below scenario

       SIP/2.0 200 OK
       Record-Route: <sip:22.22.22.22:5060;lr>,<sip:11.11.11.11:345>

    so ack is

      ACK sip:11.11.11.11:345 SIP/2.0

    ack message ruri is overwritten by strict route uri , in this case
dialog module is returning dialog matching failed error after
receiving ack from UAC , so dialog timeout is occurred after 2 min
because of not confirmed dialog state


but below scenario is working fine (both record route entries have loose route )

     SIP/2.0 200 OK
       Record-Route: <sip:22.22.22.22:5060;lr>,<sip:11.11.11.11:345;lr>

    so ack is

      ACK sip:22.22.22.22:5060 SIP/2.0
