I have a norstar with pri configured, we have a block of 40 DIDs, the setup is currently configured for 3 digits transfered by phone company. our 3 digits all happen to be 4xx and it has been working fine for the last 8 months. We are moving a few remaining copper lines over to the pri, however these numbers are would end in 2xx and 9xx, when I go into trunk/line data to configure the received number for the new numbers I get the message " '920 is not a valid option for 'received number'" (920 happens to be the 3 digits in this example), I get the same message for the other numbers I am trying to configure that are 2xx and 9xx. If i use another fake received number, for example 489, it takes it.
Any ideas on what is going on here?
