详细说明： Core features Signaling •SIP user agent compliant with RFC3261 •SIP/UDP, SIP/TCP, SIP/TLS •Supports IPv6 •Digest authentication •Supports multiple calls simultaneously with call management features: hold on with music, resume, transfer... •Multiple SIP proxy support: registrar, proxies, outbound proxies •Text instant messaging and presence (using the SIMPLE standard) •DTMF (telephone tones) support using SIP INFO or RFC2833 Media •Audio with the following codecs: speex (narrow band and wideband), G711 (ulaw,alaw), GSM, G722. Thr ough additionals plugins, it also supports AMR-NB, SILK, G729 and iLBC. •Video with codecs: VP8 (WebM), H263, H263-1998, MPEG4, theora and H264 (thanks to a plugin based on x264), with resolutions from QCIF(176x144) to SVGA(800x600) provided that network bandwidth and cpu power are sufficient. •Audio conferencing •Supports SRTP and zRTP (encryption of voice and video) •Supports any webcam with a V4L or V4L2 driver under linux and Directshow driver on windows •Acoustic echo cancelation using the great echo canceller available in libspeexdsp (works not only with speex codec of course) •Efficient bandwidth management: the bandwidth limitations are signaled using SDP (b=AS...), resulting in audio and video session established with bitrates that fits the user's network capabilities. •Adaptive audio & video bitrate algorithm to adapt to available network bandwidth. •Sound backends: ◦Linux: ALSA, OSS, PulseAudio ◦Windows: waveapi ◦MacOSX: HAL Audio Unit ◦iPhone: VoiceProcessing AudioUnit with built-in echo cancellation ◦Android sound system ◦JSR135 on BlackBerry •Can use plugins: to add new codecs, or new core functionalities, such as remote directory search of sip addresses for example. General •Addressbook •Understands SIP ENUMS (sip phone numbers using the naptr DNS service, without proxy) •Nat friendly: guesses NAT address for SIP messages, uses STUN for RTP streams •Compliant with open standarts: see the full list there. User interfaces Gtk2 graphical interface It is running for Linux, Windows and MacOSX Console tools •Linphonec is a command line interface that can use readline on linux to get completion, history, such as bash. •Linphonecsh is another command line tool to remotely control a linphonec daemon. Unlike linphonec, linphonecsh immediately exits once the command is executed. Mobile phones interfaces •Android application (with video support) •iPhone/iPad application (with video support) •Blackberry application (no video support yet) Portability •Linux/x86 and Linux/x86-64 •Windows XP and Vista •MacOS X x86 : audio and video. You can download a standalone bundle from this website or, use macports. •Linux/ARM: without graphical interface. Linphonec or liblinphone are good candidates to provide the software stack of an hardware phone or hardware communication system. •Linux/Blackfin: The uclinux.org project maintains a port of linphone for blackfin processors, without gui. Performance are impressive. See here for details. •Google Android: audio and video, download with the Android Market from your phone. •Iphone OS: audio and video, download from the AppStore on your iphone/ipad or ipod touch. •Blackberry OS: Audio only, pure j2me version of Linphone. •WebOS : unofficial port, see information here: http://www.webos-internals.org/wiki/Application:Linphone •May work also on FreeBSD and OpenBSD with minor modifications to the build system. ...展开收缩
