Mystery number.

[MasterRacker]

We've discovered a mystery number that, when dialed, directly rings through to one of our remote facilities. We don't own this number. Based on the area code and prefix, I initially assumed it was a Sprint cellphone, but I've called Sprint and they say it's not their number. A reverse lookup in

says it is an Onvoy cellphone. Onvoy (Zayo) is one of our providers but they've told me it's not their number either. I've also checked with yet another of our providers and they don't own the number nor can they find it in any of their databases.

I've done some traces on our Avaya switch and seen the following:

Trace station: call comes in with no name or number.
Trace main inbound trunk: call never hits it.
Trace trunk to remote facility: call comes in with no name or number.

I thought it might be someone's cellphone that had call forwarding turned on, but when I dial it, I don't hear any cover or forward tone and on the first ring I immediately see the hit on our switch in the trace.

Anyone have any suggestions on how to track this down? I'm thinking of having our T1 provider run a trace while I dial the number, but I can't think of anything else at this point.

Jeff,

You can start tracing it back. Call the number and find out which channel it is routing into your switch on, then call your T1 provider and ask them to see where it is coming from, then call that provider and see where it is coming from . . . . . . and just keep going till you find the switch it is coming out of and then you can ask them who owns the number!

I have seen several times where a person with a phone managed to forward the phone to another number. calls to the original number automatically went to the second number. the only cure was for the holder of the first number to cancel the call forwarding. this happened a lot with centrex in our area because the centrex forward code was 17 and the local area code was 715 so if people didn't dial the centrex 9 first and just started dialing a long distance number 1715xxx vola forward.
