SipXecs sending responses on incorrect TCP stream.
--------------------------------------------------

                 Key: XECS-1589
                 URL: http://track.sipfoundry.org/browse/XECS-1589
             Project: sipXecs
          Issue Type: Bug
         Environment: sipXecs 3.10
            Reporter: Brad Marusiak
         Attachments: polycomRepro.pcap

Sometimes starting up a polycom phone with BLF configured will result in the 
polycom unit not displaying the BLF icons on the UI.
This is caused by the sipXecs server sending its NOTIFY responses to the 
polycom SUBSCRIBE msgs on a TCP stream that was created before the polycom 
restarted and not on the stream created for the the SUBSCRIBE message.

Because the incorrect stream is used the src port, Seq and Ack are out of sync 
causing the polycom to toss the NOTIFY and thus never receive the correct BLF 
information.
