[Asterisk-Users] SPA and NAT traversal

[Michael D Schelin]

The only way you ll be able to call extension to extension is if  
Asterisk is on the same node behind the nat. like the extensions or if 
each extension is on a different node.  I run a proxie server and have 
ran through this problem many time. I bet you can call out bound to the 
outside world just fine from every extension. .
