[Asterisk-Users] Register vith SIP provider from behind NAT

[Simon Brown]

I cannot successfully register with, or even make calls to, a SIP provider
(such as FWD) with my * server sitting behind a NAT.  The firewall is a Cisco
827 router running 12.3 IOS.

Has anyone successfully got their server behind NAT to register or make a
call to a SIP provider?

TIA 

Simon
