[asterisk-users] Asterisk + Phones behind different Nat Firewalls

[Danny Dias]

Hello,

I have a doubt (basic i guess, but not for me). I have an escenario where
customer site has Asterisk PBX behind Nat/firewall with private IP address
and sone phones also; BUT there are some other phones on different sites
and of course behind its nat/firewalls; with IAX i have no problem, but
customer wants to use SIP phones and there is no way to put IP public
address for the Asterisk Server.

What do you recommend? Any advice?

Many thanks in advance
