[SR-Users] Register Forwarding

[Fred Posner]

Just to add that the path module is awesome when working with
freeswitch, other kamailio nodes, etc that support it.

With asterisk (specifically pjsip), there's been issues with path (not
sure if its pjsip itself or asterisk) rendering path useless and
requiring the change of contacts.

Daniel's post is a great solution.
