Hi *, sorry but I had to organize a conference and so there is not much time for me to answer just in time :-(

For VoIP you need more than 64 kBit/s. Also special codecs need less than this tyou get problems with other applications on the nedd and there are jitters and so on. That really not nice for all on the used "radio cahnnel" ( = conference room). So text messages are a good fallback. > 2) The VoIP client will not be part of the FG binary and therefore harder > for beginners to use. As it stands it requires knowledge of the I/O > subsystem.

My currently researches result in an apllication like squawkbox for FSxxxx. In this application should be integrated a VoIP-Client and some code for sending all necessary information for a compatible ATC client. > 3) It isn't completely clear how using Asterisk scales with the number of > users and frequencies.

Asterisk canwork with conferences >30 users. But you need a powerful machine and also a powerful internet connection. With the actuel test server this is no problem. The distance calculation should be also in the seperate program. This is more clear for the whole code. > None of these are major issues right now, and I think Holger's approach is > very exciting. :-) Regards, Holger > BTW - has anyone actually used the text chat feature?
