A main project in BerkeleyTIP is to put together our own VOIP conference server.
A likely candidate is the Asterisk system.
Videos: We've had at least one, & it should be listed here.
Currently, BTIP uses the Ekiga.net voip server, located in France. AFAIK, we've never had a problem with it. But, it could be unaccessable at some time.
Having our own serverer would give:
1) Backup reliability.
2) Customization ability.
1) Control panel, to see who is in the voip channel,
2) Multiple channels, for multiple conversations.
