10th January 2007 - Full PDF Text Version

When using IP Hard Phones (e.g. 4600 and 5600 series terminals) with Avaya IP Office, extension numbers must be limited to 7 digits.

It should also be noted that other limitations may apply - such as those for Compact Contact Centre (CCC) where extension numbers cannot be over 4 digits in length.
