I have a customer that just ported numbers to a Verizon PRI. They are having an issue in which they are sporadically getting a pre-recorded message when calling in, as if the number wasn't programmed in the incoming call routes. All numbers are absolutely programmed. They have 8 channels licensed and a full PRI. The provider is going from 23->1 and the PBX is going from 1->23. I noticed that when the incoming is working, if I make multiple calls, they will make their way up the channels, starting from 8, and the next call after channel one is used is when I start to get the pre-recorded message from the provider. I have the same exact set up in a few different places (full PRI with 8 channels licensed) and don't have this issue anywhere else. Could the issue be on the provider side?
