3-Participants Conference

VISIONPRO allows three people to converse in a single conference. it is a useful feature for consulting or conducting a meeting with colleagues over the phone, saving time and increase productivity.

Alternate Number Dialling

Whenever redial or auto redial is used, the VISIONPRO dials out the next alternative number instead of the same number that is found engaged.

Auto Attendant

The caller can directly reach an extension without the help of an operator. VISIONPRO has a built-in Auto-attendant playing different messages like Welcome Message, Dial-by-Name, Dial Extension, Busy, No-Reply, Transferring to Operator, etc. These messages can be recorded in a four minute voice module. It also allows the caller to call a desired extension by dialling the name of the extension user.

Class of Service

VISIONPRO allows the supervisor to decide upon the access rights to features for each extension, thus allowing you to configure the system as per your requirements. For example, extension 201 (middle management executive) can have features like Conference, Auto Redial, Abbreviated Dialling, Alarms, Do-not-Disturb and Call Transfer only, whereas Extension 501 (pantry) can be configured to dial intercom numbers only.

Conference Calls

It allows three people to converse in a single conference. Such dual three-party conference is possible.
It is a useful feature to consult or conduct a meeting with the colleague over the phone, saving time and increase productivity.

Flexible Numbering

This function allows you to define the extension numbers as per your convenience. You can have 1, 2, 3 or 4 digit extension numbers. Not only that but within the same system, you can also have combinations of 1, 2, 3 and 4 digit extension numbers.

Least Cost Routing

VISIONPRO can be programmed to ensure least cost incurred for each call by choosing specific trunk lines based on their prevailing tariffs. This function has a great utility now with the presence of multiple basic service providers offering various tariff plans for diverse destinations during different timings.

Remote Programming

Matrix VISIONPRO can be engineered for change in its programming from a remote location also. This does not even require a PC or any other specialized device at the site.

Abbreviated Dialling

Matrix VISIONPRO stores frequently used numbers in the system memory (90 numbers). The users
can dial out this number with its access code and index number.

Allowed and Denied list

VISIONPRO prevents misuse of long distance and international dialling to control telephone cost. A comprehensive list of numbers can be included in the Allowed and Denied Lists. However, it allows dialling of a few numbers and restricts dialling of other numbers in the same area. For example: An extension can dial only '22-628-5738' but not any other number starting with '22'.

Auto Call Back

Station user need not keep dialling busy station repeatedly. By this feature, VISIONPRO allows you to get connected as it gets free.

CLI based External Call Forwarding (ECF)

The system offers the facility of forwarding selective incoming calls to a desired external number. Selective call forwarding is possible by defining a string of numbers. For example, the system could be programmed such that all numbers with a prefix "22" are forwarded to the residence number.

CLI based Routing

The system can be programmed such that particular numbers land at specified extensions directly without the assistance of an operator, thus saving time and cost for the callers.

Direct Inward Dialling (DID)

Frequent callers can reach desired station by dialling the station number. In this feature, system will perform the task of an operator.


VISIONPRO offers great use to those stations, which make more trunk calls than internal calls. As soon as the station user picks up the receiver, he/she gets access to the desired trunk line, saving time and effort. This function also offers a variant whereby a specified telephone number may be dialled as soon as the handset is picked up, or after a pre-defined delay.

Live Call Supervision

VISIONPRO allows you to define feature access code as per your convenience. It offers users with great convenience as they do not have to remember the new codes in case the system is changed.

Programmable Access Codes

VISIONPRO allows you to define feature access code as per your convenience. It offers users with great convenience as they do not have to remember the new codes in case of change of the system.
