Since everyone these days has firewalls (and frequently low budget ones) and NAT is virtually always in use, what is the best/easiest recommendation to get SIP extensions behind one fireall to properly register/stream with Asterisk across the net behind another firewall (the “worst case scenario” that is most frequent sceanrio)?
Can/should Yate be setup as a dedicated SIP proxy between extensions and Asterisk?
Will Asterisk 1.2’s rewritten SIP support finally finagle this frustrating SIP issue?
Is there an easy How to to get SER to do it?
Have been trying to figure this out for a year, any help would be appreciated.
