Switchvox Peering

We are attempting to peer a VOIP dialer with our current switchvox installation. I have setup the sip peering per switchvox’s instructions and I’m unable to get the dialer to connect.

The idea is that we want the dialer to route all of it’s calls through switchvox so that it can utilize the PRI’s that are connected to the switchvox system.

Does anyone have any ideas on why I can’t get this to work? It seems to be failing on the registration with switchvox. Is there a better way to do this and still be able to route calls back to the dialer?
