Alkit Confero

Alkit Confero is a multimedia communication, collaboration and conferencing tool developed by Alkit Communications. The software supports synchronous high quality audiovisual communication over IP networks, shared whiteboard, text messaging, application sharing and more. Both point-to-point and multipoint communication is supported, the latter either via IP multicast or through an RTP reflector/mixer. Session initiation and control is provided based on the Session Initiation Protocol (SIP) and media is transported using the Real-time Transport Protocol (RTP), which makes Confero interoperable with a multitude of other videoconferencing and VoIP applications.


The main design goals of Confero is that it should be flexible and scalable in terms of the computer hardware and peripheral devices supported, the video quality achievable, and the need for network and CPU resources. Moreover, Alkit Confero has a software design that makes it easily customizable to many different application areas, including distributed collaborative work, telemedicine and distance education.

Alkit Confero is available in two software editions: Alkit Confero Standard Edition (SE) and Alkit Confero Enterprise Edition (EE). The main differences between SE and EE are that EE supports application sharing, higher video quality (resolutions up to 1920x1080) and media streaming. Alkit Confero SE supports up to three simultaneous participants, whereas EE supports an unlimited number of conference participants. Contact Alkit Communications for information about availability and pricing.

Alkit Confero is available for Windows, Mac OS X and Linux.
