Scenario: My Company needed to expand their Extension count beyond 300 û 399. I created Extensions 400 - 419 Their current DID inbound calling group was xxx-5000 to xxx-5099 I had SBC add another DID inbound group of xxx-5100 to xxx-5119 The challenge was to program the system to route the calls to the proper extension groups.
By looking at the printout for the PRI and then taking the terms and searching the PDF's, I was able to figure it out.
This programming is performed under System/ Lines & Trunks/ PRI/ Dial Plan Routing
The original config:
Entry Number: 0 1 NtwkServ: Any service Expected Digits: 3 0 Pattern to match: Digits to Delete: 1 0 Digits to Add: 3 0
What finally worked:
Entry Number: 0 1 NtwkServ: Any service Expected Digits: 3 3 Pattern to match: 1 0 Digits to Delete: 1 1 Digits to Add: 4 3
Note that I swapped Table #Æs. ThatÆs because the æ0Æ in æPattern to MatchÆ may have been a wild card. ( I never did check that ) So, by placing the æ1Æ and the æ4Æ in the æ0Æ table, it addressed that translation first, and all others would be addressed in the æ1Æ table.
Important: You MUST set a Service (NtwkServ) for each Table or the Table won't be acknowledged. If your Service Provider is not listed, you can try.. Misc./ Any Service.
