How do you turn off phone forwarding? Somebody inadvertently has their phone forwarding to another extension. Lucent Partner 18d.

How do I disable call fwd on Avaya 18d. I tried feature 11 (no luck)

It depends on the kind of telphonesystem and the kind of forwarding.

Generally the procedure is #code# where code is
21 for call forwarding unconditional
61 for call forwarding on no reply
67 for call forwarding when busy

On most mobile operators you can do #002# or ##002# to take the all in one go.
On some fixed (analog/PSTN/ISDN) lines you can use #001# to take them all inone go.
Some PABXes(officephones) also have call forwarding on precense (lunch, meeting. etc) and this is often turned off with #23#
