What is Kapanga?

Kapanga is a powerful and unique Session Initiation Protocol (SIP) software phone capable of voice, fax andvideo over IP communications. As a SIP phone, Kapanga can be used on Voice over IP networks to interactwith traditional Public Switching Telecommunication Networks (PSTNs) and future IP-basedtelecommunication devices. In addition, Kapanga offers several unmatched features such Voice and videoover IP recording, fax auto-answering, real-time Quality of Service monitoring (MOS) and much more.

So what can I do with Kapanga?

Call and receive Voice and Video over IP calls. Make Kapanga-to-Kapanga or Kapanga-to-phone calls*. Kapanga can be greatresource for any organization with IP-based PBX voice andvideoconferencing.

Send and receive faxes, right from your laptop or PC. In additionto placing calls or establishing videoconferencing, Kapanga enablesyou to send and receive faxes. When in auto-answer mode,Kapanga can also receive faxes automatically in the same way astandard fax machine does.

Record calls in MP3 and video conferences in MPEG format.Keep track of important calls or videoconferences without the needof expensive equipment that is difficult to install.

Measure VoIP Quality of Service in real-time. Kapanga calculatesthe Mean Opinion Score (MOS) parameter in real-time. MOS is avery useful measure of quality of service that goes beyond having

just hearing "noise" or "chopping". Service providers find MOS fieldmeasurements of great value to enhance customer service andincrease network reliability.

* Subscription to an VoIP telephony provider required
