CS1K SIP/H323 Trunks

Prodecure for building both SIP and H323 IP trunks, for use with NRS:

  1. LD 17: Create a virtual D channel (one only)
  2. LD 97: Create a virtual superloop for the trunks
  3. LD 117: Configure a bandwidth zone for IP trunks
  4. LD 16: Build two routes: one for SIP, and one for H323
  5. LD 14: Build IP trunks on the virtual superloop for each route

In the example below, only significant prompts (Rel. 7.5) are shown, terminal input is bold, notes are in blue.

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.
