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 applicable only to FXS interfaces.
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 forwards an incoming call. The
service is cancelled when the device sends an UNSUBSCRIBE request or when the subscription
time expires.
The following procedure describes how to configure the feature.
➢
To configure the call forward reminder ring feature:
1. Open the Supplementary Services Settings page (Setup menu > Signaling & Media tab >
Gateway folder > DTMF & Supplementary > Supplementary Services Settings).
2. In the 'Enable NRT Subscription' field (EnableNRTSubscription), select Enable to enable
endpoint subscription to ring reminder event notification.
