[Asterisk-Users] Re: Received VNAK: resending outstanding frames?

[Carey O'Shea]

Some more info:

Just tried this on a server without using any NAT and no port
forwarding, no masquerading, and I still have the same problem. So there
goes that idea. I do not know what this VNAK error means. 

By the way, I am using the latest version (1.2.6) of asterisk, have also
tried other versions with the same problem [1.0.9 (Ubuntu Breezy) and
1.0.7 (Debian Sarge) and 1.2.1 (Ubuntu Dapper)].

Wonder if this is something simple or not?
