Function 167: Voice mail parameters
Field 1: Energy threshold
Adjust this downward if (a.) callers in a
mailbox, on a conference call or in the auto
attendant are being disconnected and/or
(b.) messages in a mailbox are incomplete.
Adjust this upward if mailboxes are storing
messages with long periods of silence. This
sets the value used to detect energy
received by the system on any port.
Lowering this value means less energy will
be required to stay connected. Energy below this level is treated as silence.
Range: 0–65535. Default: 500.
Field 2: Recording silence value
This sets how much consecutive silence can be recorded in a mailbox before it stops and plays
the “end of recording” prompt (537). Expressed in 1/100s of seconds.
Range: 200–3000 (2 to 30 seconds). Default: 600 (6.0 seconds).
Field 3: Maximum message length
Sets the maximum message length. Expressed in minutes.
Range: 1–30. Default: 10.
Field 4: Page glare detection
Enables or disables the ignoring of page glare when using pager notification. When this is set to 1,
the system will go off-hook and send phone or pager strings regardless of dialtone detection.
Enable this field if one or both of the following occur:
• CO lines are not releasing immediately after a pager notification.
• “Phantom” incoming calls (no caller and no Caller ID) are occurring.
Range: 1 (enabled) or 2 (disabled). Default: 2 (disabled).
Field 5: Maximum messages in Recycle Bin
Sets the maximum number of messages in the Message Recycle Bin.
This is a system-wide setting.
Range: 2–40. Default: 2.
