[Serusers] record_route() problem

[Tuan Pham]

  I am trying to force the ACK and BYE messages to go through SER.  However, I seem to have a problem with   record_route().  The record route field appears to be mangled (i.e., missing “;”   and a couple of characters after the IP address).
    Here is what the Record-Route field as sent from SER:
            Record-Route:   <sip:24.5.167.173ag=9612000026130000;lr=on>
  
  What do I need to do to get the ACK and BYE messages to go through SER?   Thanks,
    Tuan
