User's Manual 26. Configuring Supplementary Services
Call forward performed by the PSTN side: When the device sends the INVITE message to
the remote SIP entity and receives a SIP 302 response, the device sends a Facility
message with the same IE mentioned above to the PSTN, and waits for the PSTN side to
disconnect the call. This is configured using the CallReroutingMode.
For analog interfaces: The following methods of call forwarding are supported:

Immediate: incoming call is forwarded immediately and unconditionally.

Busy: incoming call is forwarded if the endpoint is busy.

No Reply: incoming call is forwarded if it isn't answered for a specified time.

On Busy or No Reply: incoming call is forwarded if the port is busy or when calls are
not answered after a specified time.

Do Not Disturb: immediately reject incoming calls. Upon receiving a call for a Do Not
Disturb, the 603 Decline SIP response code is sent.
Three forms of forwarding parties are available:

Served party: party configured to forward the call (FXS device). To configure this type
of forwarding party and per endpoint, see Configuring Call Forward on page
584.

Originating party: party that initiates the first call (FXS or FXO device).

Diverted party: new destination of the forwarded call (FXS or FXO device).
Note:
• When call forward is initiated, the device sends a SIP 302 response with a contact
that contains the phone number from the Call Forward table and its corresponding
IP address from the routing table (or when a proxy is used, the proxy’s IP
address).
• For receiving call forward, the device handles SIP 3xx responses for redirecting
calls with a new contact.
