The implementation with Asterisk can be done with nearly every language. The magic application in the dialplan is EAGI(). With this function you get full AGI access and on the file descriptor 3 the audio of the stream. You have "only" to connect to a multiplayer server and if the callsign on the mp server, the user on asterisk and the frq are matching you can calculate the distance and mix up the audio streams and so on. Theoretically no problem :-) See: http://www.voip-info.org/wiki/view/Asterisk+EAGI Regard, Holger -- # ## ## Holger Wirtz Phone : (+49 30) 884299-40 ## ## ## ### ## DFN-Verein Fax : (+49 30) 884299-70 ## ## ## Stresemannstr. 78E-Mail: [EMAIL PROTECTED] ## ## ## ## ### 10963 Berlin # ## ## ## GERMANY WWW : http://www.dfn.de GPG-Fingerprint: ABFA 1F51 DD8D 503C 85DC 0C51 E961 79E2 6685 9BCF - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Flightgear-devel] FGCOM bug: Call rejected by remote
Hi, after thinking about this feature I recognized that there are some problems: Real radio has a limited range. So you can use the same frequency at every point on the world. If you can hear someone on the same frequency depends on how much power his transmitter has (and some other physical rules) and/or how far away he is and so on. But with the normal radio in a plane (or on ground) you cannot reach the whole world. And radio communication is a broadcast media. Now try to solve this with unicast media (such as VoIP). Without information about the coords of each member you cannot decide "how far away" you can be heared by other users. I have tried to fix this problem by using one well known coordinate (the one of the tower) and the next one of the plane - and a limited range. fgcom calculates which airport is most nearby your selected frequency. With the coords of this airport it can calculate how far away fgcom is and it can drop the line if it is out of range. The ideal algorithm would be some kind of conference server which gets the frequency it is responsible for, the voice streams _and_ the coords of all members on this frequency. With this data the stream for _each_ member can be mixed up (far away = quite) and send it towards each client. The problem is: that has not much to do with VoIP - so you havn't any features of VoIP and no implementations for server and client. Feel free to do so :-) Perhaps someone can extend the IAX2 protocol and write a new app_meetme.so for Asterisk which ca realise this. But I think it is not really neccessary at this time.

Yes, the design of fgcom doesn't support that at the moment. That is not a bug, but a limitation.
