[cisco-voip] My first SIP trunk
IT
it at cimgroup.com

I have decided to start playing around with SIP trunks, as my company
needs more and more varied area code terminations (we have 4 PRI's and
counting). I signed up for a demo with bandwidth.com and all they gave
me is an ip address and udp port 5060. It looks like im on my own after
that....except for my favorite mailing list ;)
Here are the steps I have followed so far:
I created a sip trunk in CCM: http://www.cimgroup.com/temp/sip_setup.jpg
I created a route pattern to use that sip trunk.

I made the proper pokes in my pix, to allow traffic from their SIP
server, to my ccm.
Then, I tried to dial 713239438822 from my IP phone -- no dice.
So, I run a debug sip on my PIX, and I try to make the outbound call
from CCM again, I am getting the following:
5175: SIP::INVITE received from inside:10.96.3.11/5060 to

Is this a problem with my PIX configuration, or my SIP trunk
configuration? Anyone have some good SIP documentation?
Thanks,
Avidan
