Substations calling external telephone(s)
From Zenitel Wiki
This article describes how substations in the AlphaCom can be configured to call external telephone number(s).
- If all lines in the SIP gateway are busy, the call will be queued. When the line becomes free, the call will automatically progress.
- Multiple phone numbers can be defined. If the first phone doesn't answer within a preset time, the call can be routed to a second (and a third...) phone number.
Configure the Call Button of the substation
The call button can be configured in two different ways to dial a preconfigured phone number.
Let's assume that the prefix to the external phone line is "0", and the phone number to call is 987654321.
Alternative 1:
Start the string with a "I", followed by the prefix number "0". Then "P", followed by the phone number.
Alternative 2:
Start the string with a "T", followed by the prefix number "0". Then "w" or "W", followed by the phone number. "w" introduces a 0.5 second pause, while "W" introduces a 1.0 second pause. See Play DAK Feature for further details.
