Summary:                    Asterisk providing SIP proxy with incorrect routing
information
Description: 
In attempts to setup asterisk with openSER, I've encountered many issues
with asterisk providing incorrect information to the proxy.  In turn the
proxy is attempting to use provided information and unable to communicate
ACKS and BYE messages back to asterisk.

A patch that could solve this would be to parse the via header, the bottom
via header indicates the address of the actual device. But that would
require some extra coding. 

With a proxy in between, NAT=yes can be bad, depending on the layout of
your network.
