Had a complaint that users were unable to dial 800500XXXX. All other toll numbers can be dialed using the 9.@ tollfree route pattern.
I put in an explicit 9.1800500XXXX and it worked.
Does this mean that the NANP dialplan installed in 5.1 is out of date? If so how to update it? Since it's not a windows box I can't get to the file.
