SBX IP 320 Features & Operation Guide
Extend CO-to-CO Connection
When a call is made between two analog CO lines using DISA or off-net call forward, the call
duration is limited by the unsupervised conference timer. After the unsupervised conference
timer expires, the call will be dropped by the SBX IP 320 system. This feature is enabled to
extend the unsupervised conference time for as long as the caller wants. If this feature is
activated, the DTMF receiver device is assigned to caller-side CO lines.
Operation
When the CO-to-CO unsupervised conference timer extend feature is activated, two analog CO
lines on a conversation will hear a warning tone 15 seconds before the unsupervised conference
timer expires and the call will be disconnected.
To extend call duration, use the following procedure:
1.
Dial the unsupervised conference timer extension code number, and the extension time
multiple digit data (1-9).
2.
The SBX IP 320 system will re-assign the unsupervised conference timer to the multiple
of the entered digits.
Ex.) The unsupervised conference timer is set to 10 minutes and the entered digit is 3,
then the timer will be extended to 30 minutes.
