I have an IP Office 9.0 with three PRIs. The system short code for 9N points to ARS 50:Main
Toll Free calls need to go out on a certain PRI, which has an Outgoing Group ID of 4. All other PRI channels are at 0.
91800xxxxxxx sends 1-800 calls to Line Group ID 4. This is a system short code and works for the extensions in the main building that use ARS 50.
There are IP Phones in an adjacent building that point to ARS Route 52, where caller id is manipulated for 911 calling. Here is the chart:
I was not the original programmer for this system but I added the last entry, 91800... It doesn't work; the caller gets a busy signal. In watching the attempted call on System Status, I see that the call is not going out on the correct PRI. I'm not sure if there is a conflict between short codes or something else? Any ideas about what I am missing?
