Install Linphone (Open Source Alternative to Skype) in Ubuntu



Looking for a Skype alternative application to make voice and video calls on your desktop? Well, Linphone is one of the best choices for Ubuntu users.

Linphone (contraction of Linux phone) is a free and open-source voice over IP (VoIP) service and SIP client developed by Belledonne Communications. It was initially developed for Linux, but now supports many additional platforms including Windows, Mac OS X, Windows Phone, iOS, and Android. It supports ZRTP for end-to-end encrypted voice and video communication.

Linphone can also be used behind network address translator (NAT), meaning it can run behind home routers. It is compatible with telephony by using an Internet telephony service provider (ITSP).

Audio codecs support:

  • Speex (narrow band and wideband)
  • G.711 (µ-law, A-law)
  • GSM
  • Opus
  • iLBC (through an optional plugin)

Video codecs support:

  • H263-1998
  • MPEG-4
  • Theora
  • VP8 and H.264 (with a plugin based on x264)

resolutions from QCIF(176×144) to SVGA(800×600) provided that network bandwidth and CPU power are sufficient
