Allowed and Denied Lists
This function prevents misuse of long distance and international dialing to control telephone cost. It allows dialing of a few fixed numbers and restricts dialing of other numbers in the same area. For example, an extension can dial only `22-2626-8573` but not any other number starting with `22`. A comprehensive list of numbers can be included in the Allowed and Denied Lists.

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

Auto Attendant
This feature allows the caller to directly reach an extension without the help of an operator. The system has an Auto Attendant that can play different messages like Welcome Message, Dial by Name, Dial Extension, Busy, No Reply, Wrong Number Dialed, Transferring to Operator etc. These messages can be recorded in a 4-minute voice module. It also allows the caller to reach a desired extension by dialing the name of the extension user.

Auto Redial Multiple Numbers
This feature redials a busy number till it gets through. The user is free to concentrate on his work while the system is trying a busy number. As soon as the number is connected, the extension gets a special ring, and the number connected is also displayed on the telephone when the call goes through. Each user can submit up to 3 busy numbers for auto redial.

Auto Call Back
When the user dials an extension, and does not get a reply, or if the extension is busy, the user can activate the Auto Call Back feature. As soon as the called extension is free or available, the dialed extension rings and gives a call back to the user, whereby the user extension rings and the call is established.

Battery Charger
The system has a built-in battery charger circuit. A single battery of 12 V, 7 A.h. can be connected to it. It allows a back-up time of 3 hours. In case of power failure, the system automatically transfers to battery and is transferred back when the power supply resumes.

CLI (Caller Line Identification -DTMF)
This function identifies the phone number of the caller and displays it on the telephone. The CLI is displayed for both internal and external caller. Even in case of a call being transferred from one extension to another, the system informs both the numbers.

CLI Based ECF (External Call Forwarding)
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, however a very important number ‘22-628-5738’ is forwarded to the mobile.

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 of the callers. Of great utility in case of long distance calls.

Digital Output Ports
Vision provides an option of connecting three Digital Output Ports (DOP), thus enabling three electrical devices like door lock, relay port, fan, etc. to be operated simultaneously. These three non-energized DOP can be switched ON/OFF manually or automatically. These DOPs can be operated locally as well as remotely.

External Music Port
This port can be used to play a desired piece of music to the caller on hold. An external music source like a CD player or FM radio can be connected to this port.

Hot Outward Dial
This function is of great use for 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 dialed as soon as the handset is picked up, or after a pre-defined delay.

3-Party Conference
It allows 3 people to converse in a single conference. A useful feature to consult or conduct a meeting with colleagues over the phone, saving time and increasing 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. You can even have conflicting extension numbers defined like 2, 22, 222 and 2222 in the same system.

Inbound Call Analysis #
Incoming calls can be stored in the memory with details like Caller Number, Trunk, Extension, Date and Time of the Call, Duration of the Speech, etc. These calls can be analysed on the basis of multiple filters like Caller Number, Extension, Missed Calls, Duration, etc. Result of the analysis can be sent to a computer through the RS232C port.

Internet Ready Port (e-Port)
A special port is provided to connect the modem to the Matrix Vision. This port connects the modem directly to the trunk line eliminating noise and thus increasing data transfer speed. Further, this e-port is an extra port leaving all regular extensions ports for voice calls.

Least Cost Routing
The system can be programmed to ensure that least cost is incurred for each call by choosing specific trunk lines on the basis of their prevailing tariffs. This function has great utility today with the presence of multiple basic service providers offering different tariffs for different destinations during different hours.

Live Call Supervision
A security feature. The supervisor can know the phone number with whom an extension user is talking.

Security Dialer
A highly effective security feature that dials 3 different numbers and plays a pre-recorded message in case of an emergency. For example, it could dial the police station and play an emergency message giving the address to the office. The Matrix Vision can be connected to any emergency switch like movement detector, smoke detector, magnetic contact, glass break sensor etc. The system can also be used to activate a hooter in case of an emergency.

Scheduled Dialing
The system can be programmed to dial a number at a predefined time. This facility is of great utility and can be used to lock ling distance calls lines at fixed timings thereby preventing misuse. If desired, the Matrix Vision can lock the long distance or international calling facility everyday after working hours. This would prevent misuse, even if the facility has been left open accidentally.

Programmable Access Codes
This function allows you to define feature access codes as per your convenience. This feature offers the users great convenience as they do not have to remember the new codes in case of change of the system.

Public Address System (PAS)
The Public Address System Port allows any station user to make announcements on external speakers.

Remote Programming
Matrix Vision can be programmed from a remote location. This does not require a PC or any other specialised device at the site.
