Is there any way to import the config from the dial plan directly to the SIP Proxy? Seems that thier should be an interface to be able to convert this for you.

The short answer is no. That said, the SIP proxy dial plan has a couple of huge advantages over the CIC dial plan: 1. Source-based routing - it can route calls differently based on where they are coming FROM. Except for location filtering, CIC is basically unaware of this. 2. Regular expressions - Using RegEx for pattern number matching (both on from and to fields) allows really complicated logic to be handled in a very small number of entries where CIC may require dozens of dial plan entries to accomplish the same thing.
