[Asterisk-Users] 2 Sip phones behind un-natted Asterisk

[Chad Brown]

I have 2 SIP phones (Cisco 7960 & XTen) behind a NAT provided by a
Linksys firewall that supports UPnP.  The Asterisk server has a public
IP. Here are the problems that I am having with this configuration...

 

1.	The 2 SIP phones can call MeetMe and have a conference but
cannot call each other. (Yes, they connect but no audio either
direction)
2.	I have verify=yes in the sip.conf for both phones. Both phones
constantly go Unreachable. (However, the connection is very fast between
* and sip phones)
3.	Sometimes but not always when I try to call phone1 phone2 rings.

 

Is this Nat messing with me or something else? In any case...Any advice
out there?

 

Thanks,

Chad
