asterisk users - Jan 2005 - Error after switching from 1.0.2 (FreeBSD) to 1.0.3 (Gentoo)

I've recently switched my * server from FreeBSD to Gentoo using the 
same configs from FreeBSD on my Linux machine, except the new Linux 
machine is running 1.0.3 where the old machine was running 1.0.2.

Whenever I try to dial into one of my DIDs, I get this in the debugs 
and the call gets dropped.

Anyone have any ideas?
