So, Asterisk is a software implementation of a telephone private branch exchange which has the full range of what has been made for modern powerful telephone systems. This statement can be proved by enumerating some Asterisk’s available options list.

Asterisk is the most trustworthy telephone exchange system because it works with not one but a number of various operators with dynamic call routing. So, in case something happens to one or more telephone operators, PBX clients won’t even feel this.

In addition, Asterisk is the most profitable phone exchange system. It’s so because every single calling route is provided by a special client plan. Calls within city limits are unlimited, for instance, and are supplied by the city line. Long-distance calls made outside the city and the country limits are provided by UcallWeconn or Betamax. Finally, every single call is made with the most profitable tariff plan allowing one to save up to 80%.

And eventually, Asterisk is the cheapest in sense of installation and support. For example Nortel – a telephone exchange system with options similar to those of Asterisk – Cisco and Avaya might cost up to $ 20.000-30.000. At the same time Asterisk’s installation and support is costless. The software implementation can be installed on next to any computer based on Linux or other similar operating systems. One should not look for additional products in case the telephone private branch exchange system fails.

The cost of support is also pleasing. Support specialists working with Cisco work for incomparably higher cost just because it’s Cisco! An Asterisk support specialist knows that he has a great deal of competitors and that’s why his work costs reasonably (or someone else will do this work).

One might claim Asterisk has no certificated specialists, compared to Cisco and AVAYA, and in case of serious problems one will have to work them out on his/her own. I would advise you, however, to remember that the main sponsor of Asterisk DIGIUM both supports Asterisk itself and supports Asterisk-based projects, customizes it to specific requirements, makes equipment and products which best fit Asterisk, are hardly any worse and more bounce to the ounce than similar systems’ products.
