Despite mobile phones taking lead on the market during the last decade, fixed-line telephony still has a lot to offer in its more modern versions. VoIP telephony (colloquially called Internet telephony) gives us unlimited possibilities of configuration which makes it an ideal solution for a company that wants to provide friendly contact opportunity to its clients and employees.

Among features of the VoIP exchanges we find:

  • Redirection, Internal numbers
  • Teleconferencing
  • IVR (option to select an item from the menu)
  • Voicemail

We base implementation of VoIP exchange on Asterisk software. It is one of the most popular systems of this type and thus one of the best developed in the world. In addition, it is an open source project with no license costs and gives vast possibilities of adapting to the requirements of a specific client.
