To build on what Ed has already added.  When you talk with your SIP provider, ask them what type of authentication they are expecting.  Some providers will do source IP with no authentication, others support a username and password on dial-peers, and others require the hidden ‘credential username password realm’ under sip-ua.  Try running ‘show sip-ua reg stat’ and see what shows as registered.  A lot of providers won’t like the extra registrations that CME / voice gateways send, so if you see 1 registration with a yes and a bunch that say no, you can trim all those down with ‘no sip-register’ under each of the offending dial-peers.

Sounds like the SIP messages are going back and forth OK but your audio stream isn't. Perhaps ACL or firewall causing the problem?

We've got a UC520 setup at a small office across town, but no SIP trunk so i'm not sure what exactly would be the cause.

CME is running as part of the IOS on the box, if it weren't running your phones wouldn't work at all. I would double check the dialpeers that CCA generated for you. From my limited experience CCA was OK for a basic configuration but as soon as we had to setup something special I got fed up with it and just started using the CLI instead.

Barring that you might want to check with your SIP provider to see if they can help with the outbound call problems.. maybe the call is getting rejected by them?
