Avaya IP Office: Unable To Forward or Transfer Calls Externally

Problem Details:

When trying to set a user’s forward number through a handset, the option to save or complete the forward does not appear. Setting an internal extension works fine and can be set, but trying an external number does not.

OR

Setting a user’s forward number through the IPO Config saves, but does not complete the forward to an external number.

OR

A call comes in to the system and is then attempted to be forwarded to an external number but does not go through and fails.

Cause:

This is most likely going to be due to the “Inhibit Off-Switch Forward/Transfer” option selected.

Solution:

Uncheck the “Inhibit Off-Switch Forward/Transfer” option under System | Telephony | Telephony and this should then allow the number to be forwarded/transferred externally.
