Abstract:  One of the SIP filters was routing SIP resonses using the wrong local port

Description/symptom of problem:  
PK50079 resolves the following problem:

ERROR DESCRIPTION:                                              
When the proxy receives a UDP SIP response from the server, it  
should forward that to the client using the local client port ( 
5060).                                                          
Currently its not using the client port, its using the          
server port (sometimes 5080).   We are also using the wrong     
port for messages received from the client.                     

LOCAL FIX:
