First, upgrade your asterisk to 1.2 ... ;-)

What is the external connection? Is it VoIP, PSTN, or ... ?

If it's VoIP then it's almost certian to be a NAT problem with your 
network/router.

There's no magic in setting up GXP2000's - they're fairly straightforward, 
and if you can do phone to phone, (via an asterisk) they're probably OK.

Let us know more about the external connection technology...
