Call Forward Reminder Ring - AudioCodes Mediant 600 User Manual

SIP 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 to Do Not
Disturb call, 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).
Originating party: party that initiated the first call (FXS or FXO device).
Diverted party: new destination of the forwarded call (FXS or FXO device).
The served party (FXS interface) can be configured through the Web interface (refer to
''Configuring Call Forward'' on page 170) or ini file to activate one of the call forward modes.
These modes are configurable per device's endpoints.
Notes:

9.18.5 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 (only if in onhook state) when a third-
party Application Server (e.g., softswitch) forwards an incoming call to another destination.
This is important in that it notifies the FXS endpoint user, if located next to the endpoint
phone, that call forwarding service is currently being performed.
Version 5.8
•
When call forward is initiated, the device sends a SIP 302 response with
a contact that contains the phone number from the 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.
