The services offered on the SIMPHONi platform are :


Prepaid Service

The prepaid service is a real-time rating and billing service that enables a subscriber to establish a debit account with the operator. As the subscriber makes and receives calls, the account is charged. The subscriber can use the service till the amount in the account is depleted. The account can be replenished by using the recharge mechanism to recharge the account with a specified amount.


Calling Card

The service allows the subscribers to make calls from any telephone and have the charges of the calls levied to the calling card. The Calling Card Service can be accessed by dialing an access code. The service allows the operators to package various options attractively taking into account various calling patterns and geography of calling.


Number Translation Services

           Advanced Freephone

This service allows a reverse charging, the subscriber accepting to receive calls at his expenses and being charged for the whole cost of the call. Also the service allows
the served user having one or several installations to be reached from all or part of the country, or internationally as appropriate, with one freephone number. The routing can be origin dependent or time dependent.

           Universal Access Number (UAN)

This service allows a subscriber to publish a single number for all the telephone numbers that he can be accessed. Routing to the appropriate number can be configured by the subscriber through an IVR or the WEB.



Mass Calling and Televoting

This service allows the subscriber to propose a phone voting, the user being asked either to ring a specific number according to his choice, or to ring a unique number and, after prompting, to give his choice by keyboard or by voice dialogue.

Televoting enables subscribers to survey public opinion using the telephone network. Persons wishing to respond to an opinion poll can call advertised televoting numbers to register their votes. The charging is to the discretion of the service subscriber.

Using this service, the network operator can temporarily allocate numbers to the served user. Each time a call is made to one of the numbers by an end user, the user will be played an announcement acknowledging the call, and a count of calls made to this number will be incremented. When televoting has ceased, the network operator will supply details of the total numbers of calls made to each number to the served user and the special numbers will be reallocated. Calls made to these special numbers may be charged at varying rates.



Incoming call screening (ICS)

The ICS service allows the service subscriber to screen his incoming mobile phone calls.
Main screening features include Selective Call Acceptance, Selective Call Rejection and Password Call Acceptance



Virtual Private Network (VPN)

A VPN is a public network based service for interconnecting corporation locations (regional, national, international). VPN can be configured in the Fixed/GSM/CDMA networks. The service uses the public switched network to provide features and capabilities of a private network such as private numbering plan, private access, multiple locations and customer control over network administration.
