Looking for some help with Avaya Wireless 3626 phone. We recently converted from 5 digit dialplan to 10 digit dialplan (CM 5.2.1). The 3626 will only accept a 7 digit extension number on the handset itself. Does anyone know if this is just the phones capability, or is there possibly a firmware upgrade that would allow this phone to have a 10 digit extension number. Any assistance would be greatly appreciated. Thanks!
