Auto Redial - Matrix Visionpro System Manual

Auto Redial

The Auto Redial feature retries an external call automatically if the dialed number is busy. It repeatedly checks the
busy line till it is free. When the called number is no longer busy, the system places a ring on the caller station.
Auto Redial saves time and the effort of repeatedly dialing the entire phone number over and over until the call
goes through.
The Auto Redial feature is supported for external numbers only. VISIONPRO also allows multiple Auto Redial.
Three different numbers can be set for Auto Redial simultaneously.
How it works
When you dial a number and get Busy Tone, you can set Auto Redial by dialing its command. When Auto Redial is
set,
• VISIONPRO checks for a free trunk to dial the number.
• VISIONPRO dials out the requested number and waits until the 'Auto Redial - Ring Back Tone Wait Timer
expires to sense the Ring Back Tone from the requested number. This timer is programmable and is set to
60 seconds by default.
• If the system does not detect Ring Back Tone for 60 seconds, it releases the trunk, increments the Auto
Redial Retry Count and tries again after some time. Otherwise, if the system detects a Busy Tone, it
releases the trunk, increments the Auto Redial Retry Count and redials the number automatically after
some time. This process is repeated until the system detects the Ring Back Tone.
• When VISIONPRO detects the Ring Back Tone instead of the Busy Tone, it places a ring on the station
that has set Auto Redial. The station rings for the duration of the 'Auto Redial Ring Timer
programmable and is set to 45 seconds by default.
• The station must go OFF-Hook to get connected to the external party.
• If the station is in the middle of any activity such as dialing, ringing or in speech, VISIONPRO suspends
Auto Redial until the station becomes idle again. Later on, it dials the requested number again.
To change the number of redial attempts and the interval between them, you must configure the Auto Redial Retry
Count and the Auto Redial Retry Interval respectively. In addition to these, the system has two other related timers,
which can be configured to match user preference:
• Auto Redial Ring Back Tone (RBT) Wait Timer
• Auto Redial Ring Timer
6. Time for which VISIONPRO waits to sense the RBT from the PSTN/CO Network after dialing the requested number.
7. Time for which the station that has requested Auto Redial should ring.
