Customer has had an IP Office 406 running 4.2 software for years and they decided to upgrade to IP500v2 running R9.0 software. They are in a remote area and have a Verizon PRI. The old config shows the switch type as "5ESS". The central office is a DMS10. (The only way it would work on the old system is to configure it to be a "5ESS".)
When I installed the IP500v2 (all licenses and new hardware is in place and valid) the PRI acts like it is going to work and then if you watch System Status then all (or a couple of times 1 or 2) B-channels go from "Idle" to "Out of Service". If you unplug the PRI then they will go all go out of service. When you reconnect the line then they will flash "Idle" and then go back to "Out of Service".
We have been able to make a few calls but no incoming calls can come in and after a successful call is ended then no more calls can be made.
I talked to someone with Verizon and they show no problems with the D-channel. If I change the PRI switch type to "NI2" all of the channels will show to be "Idle" but you still can't make or receive calls. Changing the switch type to any other choice still results in the channels to appear as "Out of Service".
I'm not sure if it a problem with the hardware on the new system or if it is a software issue on R9.0.
I ended up switching back to the old hardware and downgrading the expansion unit back to the old software release and the PRI synched up immediately.
Unfortunately, this customer is 250 miles away. I'm not sure what steps to take next. I'm torn between seeing if R8.1 software would work but I'm not happy about having to pay to downgrade the software to a different release or changing out the hardware in case there is a problem with the PRI card.
Does anyone have any ideas?
