Call Forward
You can configure your phone to forward incoming calls to another party by the static forwarding. You can also
forward calls while your phone is ringing, refer to the dynamic forwarding.
Static Forwarding
Three types of static forwarding:
• Always Forward: Incoming calls are immediately forwarded.
• Busy Forward: Incoming calls are immediately forwarded if the phone is busy.
• No Answer Forward: Incoming calls are forwarded if not answered after a period of time.
For advanced users:
Call forward allows users to redirect an incoming call to a third party. IP phones redirect an incoming INVITE
message by responding with a 302 Moved Temporarily message, which contains a Contact header with a new URI
that should be tried.
The server-side call forward settings disable the local call forward settings. If the server-side call forward feature is
enabled on any of the phone’s registrations, the other registrations are not affected. DND activated on the IP phone
disables the local no answer forward settings.
The call forward on code and call forward off code configured on IP phones are used to activate/deactivate the
server-side call forward feature. They may vary on different servers.
IP phones support the redirected call information sent by the SIP server with Diversion header, per draft-levy-sip-
diversion-08, or History-info header, per RFC 4244. The Diversion/History-info header is used to inform the phone
of a call’s history. For example, when a phone has been set to enable call forward, the Diversion/History-info
header allows the receiving phone to indicate who the call was from, and from which phone number it was
forwarded.
Forward International
Forward international allows users to forward an incoming call to an international telephone number. This feature is
enabled by default.
Procedure
Call forward can be configured using the configuration files or locally.
