VoIP Special Interest Group

Mission

To package as many Voice over IP applications as possible for Fedora. To that end, members of this SIG will assist in packaging VoIP applications and make reviewing VoIP-related packages our priority.

Process

Want to suggest a VoIP application or library? Just add it to the Applications/Libraries of Interest list. Working on packaging a VoIP application or library, or need a review for your VoIP-related package? Just add it to the Applications/Libraries Being Packaged list. Interested in joining the SIG? Just add your WikiName to the list.

Federating VoIP and real-time communications with open standards

You can help build a world of free communications based on secure, open standards by deploying SIP and XMPP on your Fedora and Red Hat servers. See the Federated VoIP quick start HOWTO for details.

Desktop Integration

Click to call

click-to-call is a pharse used for functionality when a desktop user initiates VoIP-call from desktop software. There are different use cases when this could happen:

  • desktop application, that is linked to CLI binary with arguments: kaddressbook
  • web browsers clicking href=tel: that either have a plugin or CLI-helper that is executed with arguments. Related documentation: rfc3966, apple.com - phone links

Second part to click-to-call is targeted phone system, wether that is nearby PBX (Asterisk), a local desktop softphone or hardphone (Cisco SOAP/XML, etc).

Applications/Libraries of Interest

  • Asterisk-Addons
  • Asterisk-Sounds
  • Call Control - a prepaid application that can be used together with OpenSIPS call_control module and CDRTool rating engine to limit the duration of SIP sessions based on a prepaid balance. It can also be used to limit the duration of any session to a predefined maximum value without debiting a balance.

    • This may require importing OpenH323 from the old Fedora package into Fedora Package Collection because Fedora dropped OpenH323 once GnomeMeeting/Ekiga switched to Opal.
  • kphone interesting SIP-phone project for KDE that never had enough activity.
  • MSRPRelay - it helps in NAT traversal of media sessions between endpoints located behind NAT.
  • SIP chatserver - an open source conference bridge that supports MSRP chat sessions.

  • SFLphone - the open-source enterprise-class SIP/IAX2 softphone (This project is now called ring. https://ring.cx/ It depends (among other things) on openDHT for which a review request was open some time ago: 1377762)
  • SIP SIMPLE client - a Python software library that allows for easy development of Internet communications end-points based on SIP and related protocols for voice, rich presence, session based instant messaging (IM), file transfers and desktop sharing.
  • sipXecs - a SIP Unified Communications solution for your enterprise.
  • Yxa - transaction stateful SIP stack and a set of SIP server applications
  • GreenJ - GreenJ is an open source Voice-over-IP phone software using pjsip and Qt
  • Homer conferencing - Homer is a free cross-platform SIP softphone, which also supports video conferencing. It can't be include in Fedora repository because it use ffmpeg. A review request is open on RPMFusion repository.
  • Jitsi - an audio/video and chat communicator that supports protocols such as SIP, XMPP/Jabber, AIM/ICQ, Windows Live, Yahoo! and many other useful features.
  • Blink - Blink is the real-time communications client using SIP protocol. You can use it with many SIP providers, on the LAN using Bonjour and SIP2SIP free service.

General Issues

* Legal status of iLBC prevents it from inclusion into Fedora, so you should check that your application doesn't use it before submitting it to Fedora/EPEL.

Now iLBC can be included in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=728302#c26

A new review request for WebRTC, that include iLBC codec, should be open nearly. A first package and spec file can be found here: https://bugzilla.redhat.com/show_bug.cgi?id=728302#c41
