Enabling Call Forwarding; Call Forward Reminder Ring - AudioCodes Mediant 500L User Manual

User's Manual

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 618.

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.

27.6.2 Call Forward Reminder Ring

The device supports the Call Forward Reminder Ring feature for FXS interfaces whereby
the device's FXS endpoint emits a short ring burst when a third-party Application server
(e.g., softswitch) forwards an incoming call to another destination. The ring is emitted only
when the endpoint is in on-hook state.
The feature is useful in that it notifies the endpoint user that a call forwarding service is
currently being performed. The device generates a call forward reminder ring burst to the
endpoint upon receipt of a SIP NOTIFY message containing a "reminder ring" xml body.
The NOTIFY message is sent by the Application server to the device each time the server
