CUCM 7 SIP Trunk Logs

I've got myself a CUCM 7 lab and I'm trying to connect to a SIP Trunk provided by Link2Voip.

I've setup the paramaters for the trunk, changed the security profile for digest authentication, and created a SIP Realm, however when I dial out I'm getting fast busy tones.

Obviously something isnt configured correctly, and I'd like to know where I can see the authentication logs so I can see why its not working.

Does anyone know where I would look?

I would follow this guide to get traces:

You can turn everything off except for the SIP options if you just want to see the SIP messaging.

Just in case you haven't seen this, Jeremy - The current strong recommendation is to use CUBE to terminate the SIP trunk for a variety of reasons. See Christina's recent post below where she outlines a number of them.

And I forgot this tool, which is what you should use to decode the traces once you get them downloaded. This a tool that TAC uses as well to look at complicated CUCM traces:
