Issues with new trunk

Brought on a new inbound DID provider, as one of my customers has some 800 numbers, and bulk911 is very competitive for their 800 service. the inbound call hits my PBX, but i get the dreaded, number is not in service. I have 30 other inbound routes and 6 other trunks, and none of them have given me issues anywhere close to this. have deleted trunks/routes still no luck.

You would need topost more expansively, show a log of a failed call and show how you provisioned the trunks and inbound routes for those DID’s

My first impression is that “number is not in service” sounds like it’s not being directed to your PBX in the first place
