Comparison of VoIP software

From Wikipedia the free encyclopedia

This is a comparison of voice over IP (VoIP) software used to conduct telephone-like voice conversations across Internet Protocol (IP) based networks. For residential markets, voice over IP phone service is often cheaper than traditional public switched telephone network (PSTN) service and can remove geographic restrictions to telephone numbers, e.g., have a PSTN phone number in a New York area code ring in Tokyo.

For businesses, VoIP obviates separate voice and data pipelines, channelling both types of traffic through the IP network while giving the telephony user a range of advanced abilities.

Softphones are client devices for making and receiving voice and video calls over the IP network with the standard functions of most original telephones and usually allow integration with VoIP phones and USB phones instead of using a computer's microphone and speakers (or headset). Most softphone clients run on the open Session Initiation Protocol (SIP) supporting various codecs. Skype runs on a closed proprietary networking protocol but additional business telephone system (PBX) software can allow a SIP based telephone system to connect to the Skype network.[1] Online chat programs now also incorporate voice and video communications.

Other VoIP software applications include conferencing servers, intercom systems, virtual foreign exchange services (FXOs) and adapted telephony software which concurrently supports VoIP and public switched telephone network (PSTN) like Interactive Voice Response (IVR) systems, dial-in dictation, on-hold and call recording servers.

Some entries below are Web-based VoIP; most are standalone Desktop applications.

VoIP software with client-to-server encryption[edit]

The following table is an overview of those VoIP clients which (normally) provide client-to-server encryption.

Client name Encryption protocols
Skype[59] A custom protocol
Notes
  1. ^ End-to-end authentication protects communications from man-in-the-middle attacks by the service provider.
  2. ^ a b Only if the user has registered with a compatible SIP provider. Some SIP providers do not support certain encryption protocols.
  3. ^ a b Only the encryption related source code is open.
  4. ^ Only on the network connection, not on the end-to-end layer.
