Voicemail is a computer based system that uses a phone network as a conduit and allows subscribers to exchange personal voice messages, select and deliver voice information and process transactions using a telephone. They contain a UI to select, play and manage messages; a delivery method to play or deliver the message; and a notification ability to inform a user of a waiting message.
Traditional voicemail evolved into Unified Communications (UC) that includes voice to SMS/MMS, email, IM, SMS and MMS. With missed call notification, availability alert and call control, it has further evolved into Call Completion (CC) with full messaging capabilities.
Multimedia Messaging Service Center (MMSC)
Multimedia Messaging Service Center (MMSC) is a standard way to send messages that include multimedia content to and from mobile phones. MMS is an evolution of SMS and extends the SMS capability that allows the exchange of text messages up to 160 characters in length. MMS technology is independent of the bearer transport. MMS messages can be transferred over existing GSM networks (over WAP), over GPRS networks and later over 3rd generation networks (WCDMA).
The most popular use is to send photographs from camera-equipped handsets. It is also used on a commercial basis as a method of delivering news and entertainment content and scannable coupon codes, product images, videos etc. MMS can deliver a variety of media including video, single or multiple images and audio.
Short Message Service Center (SMSC)
A Short Message Service Center (SMSC) is a network element in the mobile network that is responsible for handling SMS operations (store/forward/convert/ deliver). Since SMS uses the signaling channel, these messages can be sent and received simultaneously with the voice/data service over a GSM network.
Some of the more common applications of SMS are:
- Exchanging small messages as it is cheaper and quicker than a phone call.
- Send e-mail messages (<160 characters) from a handset to e-mail via SMS.
- Services like news, weather, balance enquiry etc. can be provided.
SMS revenues will continue to increase as SMS produces more user engagement than any other access method. Although unchanged, the ubiquitous nature of SMS as well as its reach, reliability, speed and ease of use has contributed to its success.
Bulk Messaging Manager
Bulk Messaging is the dissemination of large numbers of SMS or MMS messages for delivery to mobile phones anywhere in the world.
Media companies, enterprises, banks and consumer brands use it for entertainment, enterprise and mobile marketing, fraud control, alerts, reminders and information and communication.
A Bulk Messaging Manager (BMM) consisting of hardware and software is required for sending and receiving bulk messages. It provides users with the opportunity to add as many phone numbers as required, via a TXT or CSV file, and these phone numbers can be managed in a variety of ways. Duplicate numbers can be removed, all numbers are validated prior to sending the messages and the messages are scheduled for delivery at specific times and days.
Spam, Virus and Content Management
Unified Threat Management (UTM) is the evolution of the traditional firewall into an all-inclusive security product within one single system. Complexity is reduced as organizations can have a single security solution (and a single vendor) for antivirus, content filtering, intrusion prevention and spam filtering functions. Simplicity and easy management is achieved as multiple software installations are eliminated and everything can be managed via a web-based GUI.
There are currently five recognized types of virus namely File Infector Viruses, Boot Sector Viruses, Master Boot Record Viruses, Multi-Partite Viruses and Macro Viruses. Spam is similar to the email junk mail except that it is far worse as it can cost individuals and organizations time, money and a loss of data and confidential information.
To manage security, organizations typically deploy a Postfix server (or MTA), an Amavisd interface, a Clam AntiVirus engine and a SpamAssassin mail filter.
