First let me say I have a strong feeling this is a carrier issue but want to make sure I am check everything within my control.
This is a new installation, 5000 with 13 channel PRI, and MAS (UCA & NuPoint)
On Wednesday we installed the system and tested the PRI using the test DID the carrier setup for us.
- Inbound worked
- outbound worked
On Thursday we added the MAS portion of the install and tests the voicemail and UCA clienb
- Inbound worked
- Outbound worked
- UCA worked
- Nupoint worked
On Friday (Cutover day)... called the carrier and had them port the numbers over
- inbound works
- outbound does NOT work, phones get a fast busy tone.
Carrier is saying everything on their end is fine and hasn't change since our testing on Thursday so it must be an issue with the 5000. To be save I opened a ticket with Mitel and after confirming the programming is correct we took a look at the system output
Mitel is saying the carrier is sending a disconnect to the system:
ISDN Cause Code No. 90 - non-existent CUG.
This cause indicates that the specified CUG does not exist.
The carrier is going to have someone out to check the PRI Monday morning, untill it is resolved the customer can't make outbound calls and I am wondering if there is anything else I can try over the weekend in attempt to fix things AND to rule out any possibility the cause is on my end.
Any suggestions would be appreciated.
