I'm having a weird problem with a MiVoice 250 using a PRI.
Recently the customer reduced their number of B-Channels from 23 to 14 to help cut costs, they also reduced the number of retained phone numbers. The phones were setup so that the outbound caller ID of their extensions was their name and their Direct Number. A few of them even have their extensions forwarded out to their cell phones, as they are almost never in the office.
About 2 weeks later, they experienced a problem where they were unable to make outbound calls. Incoming calls were not affected, unless they were forwarded out to a cell phone. If you dialed an invalid phone number, the tel-co provided the recording saying your call could not be completed. but if you dialed correctly, then you would get about 6 seconds of dead air and reorder tone. None of the B-Channels would engage. The Tel-co could see the invalid attempts, but could not see any of the failed calls.
Through sheer dumb luck, i found that when i removed the Names off of the outbound caller ID, outbound calls began to work again. I had to disable the "Propagate outbound caller ID" in order to make calls forwarded to cell phones function.
The customer doesn't like this as calls coming to cell should the main Pilot number instead of the caller, so if the call gets disconnected, they don't know who to call back.
The Tel-co says nothing has changed in the customers account information, and their call screening table is clear. I can set the outbound caller ID number to anything i want without causing a problem. But if anything is in the Name section, the call fails. The Tel-co suggested that if they aren't blocking numbers, why would they block names.
Can anyone think of what could cause this to happen, or some way to propagate the incoming caller ID without the name portion?
Thanks
