[Asterisk-Users] An example config for using a Wildcard X100P and a SIP phone?

[Jason]

Hello.

I've just recently purchased the Asterisk Developers Kit so we can 
figure out how to get away from our Nortel system and go to IP based 
phones. I have a RH 9 box loaded with Asterisk (a very recent cvs download).

Either way, I can call the asterisk box and get their demo playing fine. 
I can even call the SIP phone I've hooked up when I call in from my cell 
phone to the asterisk box, and that works.

I cannot call out with my SIP phone though. It'll dial, ring my cell 
phone twice and then give up and complain that its busy. Even if I try 
to answer the cell phone during the first ring.

Does anyone have a config they could share with me on how to make this 
setup work? This sounds like it should be fairly trivial, but I've 
beaten my head against the wall on this for a few days. =)

Thanks alot,
Jason
