Have a strange one I was hoping someone could shed some light on. We have a customer we converted over to PRI several months ago and have had erratic problems ever since. Installation is MICS 0x32, 6.1 S/W. Customer is answering for 10 different orginizations, so we pointed each DID to a specific hunt group assigned to that particular company and all sets are members of each hunt group. The customer also has 800 numbers pointed to the local DIDs for each orgianzation and 99% of the callers dial those numbers. Problem is periodically, a call for company "A" will ring in under the Hunt group for Company "B". This had gone on for a few months with us being unable to re create the problem while onsite. I installed an SMDR box to see what was going on and when the problem occurs, the LEC is indeed sending the "wrong" DNIS digits for the number that was dialed. I feel certain the problem is on their end but they say no. To make things more bizzare, I can call the 800 number in question from a land line, and it will come in correctly, call the same number from my Nextel and it will hit the wrong hunt group just about every time. Bell says it's prob the 800 provider which I tend to agree with, but they say they have checked all the numbers and they have them pointed to the correct numbers. Anybody have any ideas on what I should tell them to look at? :bang:

If you can recreate the Nextel issue almost every time I would request a joint vendor meet with a switch tech from the 800 provider. They should be able to run a trap based on land line call vs. Nextime cell calls and see where it's breaking down.

I agree on that one. It sounds like more of an inter-exchange issue than something local at the end office (Bell). I have seen similar problems that ended up having to do with routing though toll switches, not the local office. Calling from a Nextel almost certainly will result in the call routing through a toll switch. It's not common for cell carrier's land line trunks to terminate directly at an end office.

Of course, you could ditch the Nextel. I never liked them anyway!

Nextel = Verizon. Tells you everything.

have the local carrier trap the call since it is a pri they can run a d-channel trap which will give them a complete snap shot of the call. Also have them verify the calling party number and called party number type...see if they are marking the calls as national, or unknown I have had problems with nextel in the past not properly translating calls due to improper transaltions. national seems to be the perfered choice these days

Just a Maybe to throw into the scenario. When the inner office personnel make outgoing calls surely they only have access to their own personal line group. Just in case they might be using a line group access code such as 9 they might place outgoing calls on a line that belongs to different group. Recipient of the call via caller ID returns the call to the number on their display.
