 No, I think you have misunderstand (perhaps my english is not good
 enough - sorry). ATIS in FG is ok - but not in multiplayer mode with realtime
 radio. 
   

It's no problem to allow ATIS to be turned off.  I haven't had a working 
self-compiled build since the OSG switch so can't look at the moment, 
but does fgfs --disable-atc exist, and if so does it disable the ATIS?  
If not, it could be made to, or an extra --disable-atis option could be 
added.

What I originally assumed, was that when a real-time voice server became 
available, only some channels would be manned be real people (due to 
logistics) and that the server would communicate in some manner to each 
FG instance that connected to it which stations would be handled by the 
server and which would be handled by FG.  Does that still sound 
reasonable, or am I misunderstanding what you've done?

Cheers - Dave

Jon,

first of all: thanks for testing! There were some problems with the
conference system and I fixed them yesterday (thanks Martin!).

I am not sure if I made a static or a dynamic binary of iaxcli... I will
fix this soon. Until the fix is on the web you can try to compile iaxcli
by yourself. It should be easy if you have libiaxclient, libspeex and
libgsm installed. On Debian you only need to do

$ apt-get install perl libexpect-perl libcompress-zlib-perl libiaxclient-dev 
libspeex-dev libgsm1-dev flightgear

(Perhaps you have already some of the packages... feel free to install
what you like :-) )

Or go to the folowings sites to get the sources for the library:
- http://ftp.digium.com/pub/libiax/
- http://www.speex.org/downloads/
- libgsm... hm, sorry I cannot find any sites for this lib :-(

 Hi all,
 
 I am (___very___) proud to present fg_sqawk-0.2beta. This is a
 simple prototype package for realtime voice communication for
 FlightGear based on VoIP (Asterisk and IAX2).
 
 You only need to make slightly changes to Flightgear. See the INSTALL
 file inside the distribution. I hope the package will not make much
 problems.
 
 NOTE: This is a prototype... not everything might be work as it should
 be. Give it a try and I will see what I can do for the next releases.
 
 If you have questions or want to help fix problems with this package
 please don't hesitate to contact me!
 
 http://squonk.abacab.org/dokuwiki/fg_sqawk
 
 There is still much to do:
 - eleminating the conference-call messages
 - the PTT-Key y is transmitted via the external protocol only every
   second, which is much to long for realtime conversation
 - Equalizer, that makes real radio sound (perhabs some noise in
   background :-) )
 - ATC radio (with simple radar screen)
 - ...

I've just been trying to get this running, but have run into a few

Edit/remove line number 218101 in Airport/apt.dat.  Also see KAMA Rick
Husband Amarillo Intl on line 208997.  That airport uses 118.85 for
ATIS.

According to AIRNAV these two airports do use 118.85 for ATIS:

Hmmm... you misunderstand my approach for voice communication:
There is a voice-server in thebackground which has for every frequency a
conference room (as a simulation of radio frequencies).

Ok, I have a air2air communication at 123.45 which can be easily
replaced or supplemented with 122.75 - but this is also only a VoIP
conference room :-)

 There is still something confusing about this.  Please consider
 the following comparisons:
 
   FACT   ANALOGY
 
 Radio is a broadcast medium.   Any broadcast is in some ways a
 type of conference.
 
 Radio has a limited propagationA conference room has a limited
 range. size.
 
 KSFO ATIS broadcasts on 118.85 Imagine a onference room with a
 (and several other frequencies).   boombox constantly playing in the
 room.
 
 No aircraft should be transmitting There should never be any VOIP
 on 118.85. traffic generated by ATIS.

Yes right.

 
 
 Except as noted below, I cannot think of any reason why it would
 be necessary or in any way desirable to defeat the ATIS function.
 If there is a reason, please explain.

The reason is that I would like to play ATIS trough the realtime-radio
and not from FG.

As I know the current multiplayer mode of FG is only a position
repeater/broadcaster. But what with the other realistic things as
weather and the time? I think it would be nice if someone can set the
waether of the multiplayer-session and the time. Then he has also to generate
the ATIS. And then it is a problem with the hard-coded ATIS from FG...

Ok I am some steps in the future - sorry.

 The only reason to defeat the /internal/ ATIS function would be
 to replace it with a better ATIS function ... in which case you
 would need to deal with many, many ATIS frequencies, not just
 118.85.

My current VoIP-Implementation (=Asterisk) hast all north american radio
frequencies as a conference room so there _are_ may ATIS frequencies and
not just 118.85 :-) 118.85 is the frequency by default if I press the
change button on COM1... so if I find a way to supress ATIS in FG I can
play my own ATIS when conecting to 118.85.

 Certainly we need a better ATIS function, but moving to /no/
 ATIS function would be a step in the wrong direction.

No, I think you have misunderstand (perhaps my english is not good
enough - sorry). ATIS in FG is ok - but not in multiplayer mode with realtime
radio.

Holger
