Linphone is an open source (or free software) SIP Softphone, with support for several codecs.
It runs using a gtk interface linux and windows.
Besides the graphical interface, some command line interfaces are available, called linphonec and linphonecsh, the lastest being easier to use from scripts.

Features

  • Voice, video, and text instant messaging
  • SIP protocol - interoperate with most SIP-compatible phones and proxies
  • SIP proxy support: registrar, proxies, with digest authentication
  • IPv6 support
  • Video codecs: H263-1998, MP4V-ES, H264, theora
  • Audio codecs: wideband speex, gsm, speex, g711, ilbc
  • Video format up to SVGA
  • Echo cancelation

Portability

  • Linux on x86, x86-64, arm, and blackfin processors
  • Windows XP and vista

It uses the GNU oSIP stack.

If you want to use Linphone, please make sure that you are using ALSA sound drivers and not OSS.
Linphone should work with OSS, but most of the time you will get the most mysterious erors you have ever seen, and _if_ you hear sound, it will be slow and bad quality with OSS drivers. With ALSA sound drivers, sound quality and response is perfect.

333Linphone is excellent

by beccon, Friday 09 of March, 2007 [22:25:13 UTC]
Just tested the current Linphone Windows Version (linphone-wx.exe) with my Asterisk 1.2 server. Images and sounds are excellent (much better than I ever experienced with any other video software) The key to a good image is the correct setting of bandwidth (settings/codec settings/bandwith) If the bandwith is set too high the image will disintegrate during movements. Linphone is really great as it is the only SIP videophone software I know of which is Open Source, compatible with Asterisk and available for Linux as well as Windows. Lets hope it gains momentum by users, distributions and developers.

333Testing sound quality

I have done some tests of linphone and kphone against asterisk voicemail.
And for sound quality linphone is a clear winner. It even sounded clearly better than kphone when linphone were using the gsm codec and kphone ulaw or alaw.
