CS1K SIP/H323 Trunks
Steps to build SIP and H323 IP trunks, for use with NRS:
- LD 17: Create a virtual D channel (one only)
- LD 97: Create a virtual superloop for the trunks
- LD 117: Configure a bandwidth zone for IP trunks
- LD 16: Build two routes: one for SIP, and one for H323
- LD 14: Build IP trunks on the virtual superloop for each route
- LD 32: Diagnostics / STATus
CDP is used to send calls to the appropriate route:
- H323 endpoints, eg: CS1K / BCM
- SIP endpoints, eg: IP Office
See Building a Co-ordinated Dialing Plan (CDP) for these steps (LD 86 & 87).
Endpoints must be registered with the NRS, with the appropriate routing entries.

4Diagnostics:
IP trunks should establish, and be active.
If the DCH is 'stuck', try RST DCH 252 (reset) in LD 96. It should immediately re-establish.
