Wondering if anyone has ever ran into this issue before for inbound calls into a MiVB system. All Calling Party numbers whose 10 digit number ends with the digit 0 will hear 1 ring and then hear a dial tone sound. Inbound calls work fine from all other numbers.
example: XXX-XXX-7470 calls a MiVoice Business number and hears 1 ring and then gets a dial tone sound.
XXX-XXX-7471 can call a MiVoice Business number just fine.
