Troubleshooting: If Call Forwarding Does Not Work
The server-based and local call forwarding features do not work with the Shared
Call Appearance (SCA) and Bridged Line Appearance (BLA) features. If you have
SCA or BLA enabled on your handset, you will need to disable the feature before
you can use call forwarding.
The call server uses the Diversion field with a SIP header to inform the handset of a call’s
history. For example, when you enable call forwarding, the Diversion header allows the
receiving handset to indicate who the call was from, and the handset number it was forwarded
from.
