Hello,
GSoC2010 selected projects were announced several days ago. I want to welcome Marius Bucur, students at Computer Science Faculty in Bucharest. He is going to implement our proposed project about presence support for audio conference mixers: http://www.sip-communicator.org/index.php/GSOC2010/Kamailio4575
It will be tight related to implementation in SEMS conference mixer: http://www.sip-communicator.org/index.php/GSOC2010/SEMSAudioLevels
Shortly, is about getting presence updates about participants in a conference room, who is speaking, audio levels of speakers, etc. SIP Communicator is a softphone that has support for this features, see a presentation about it at: http://www.kamailio.org/events/2010-FOSDEM/SIP.Communicator-FOSDEM-2010.pdf http://www.sip-communicator.org/
Please provide Marius hints and guidelines as fast as you can for him to get quickly into application architecture. Along with me, Marius Zbihlei will officially help in mentoring, if you have questions about GSoC project administration, etc., contact one of us.
Cheers, Daniel
