Call Forward
Call forward allows you to redirect an incoming call to a third party.
There are two types of forwarding:
•
Static Forwarding - This is used to forward incoming calls to another party.
•
Dynamic Forwarding - This is used to forward incoming calls to another party while the phone is ringing.
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 certain period of time.
Call forward can be configured on a phone or a per-line basis depending on the call forward mode. Two types of
call forward modes are:
•
Phone: Call forward is effective for the specific phone. By default, it is enabled.
•
Custom: Call forward can be configured for each or all accounts.
IP phone redirects 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.
Diversion/History-Info
IP phone supports 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 IP
phone of a call's history.
For example, when call forward is enabled on the phone, the Diversion/History-info header allows the receiving
phone to indicate the caller's name/number and number of the forwarding party.
Forward International
Forward international allows users to forward an incoming call to an international telephone number. By default, this
feature is enabled.
