Chapter 3. System Features
Answer Supervision for Voice Mail
This feature allows the DBS 576 to send an answer signal to third-party Voice Mail systems.
Without this feature a third-party Voice Mail cannot receive a signal indicating that a DBS DBS 576
extension has answered. In other words, to determine that the extension has answered, the Voice Mail
system would have to wait until the extension stops receiving ringback tone. As a result, waiting for
the ringback to stop often delays connection times for calls from Voice Mail to extensions. By sending
an answer signal, this feature provides quicker response time between the DBS 576 and the Voice
FF1-0 23: Voice Mail Answer Supervision ID Code
FF3-0: SLT Voice Mail Connection
FF1-101: DTMF ON/OFF Pattern 2
The digits used for the answer signal code are determined by the requirements of the Voice Mail
The answer code may be up to 4 characters and consist of the characters 0 - 9, *, #, and pause.
If the called extension does not answer and is forwarded to Voice Mail, the DBS 576 sends a Call
Forward ID code back to the Voice Mail system.
During transmission of the answer signal code, other DTMF digits and functions from the DBS
576 extension are ignored.
The Voice Mail port must be assigned as a Voice Mail port connection.
The DTMF pattern is set as pattern 2.
