FreedomVoip

Coming soon. 

Using the Freeswitch Based Whistle platform in our Network Operations Center and as part of our tower build. 

Free (as in freedom and beer) telephony for all.



These are some notes for linphonec, the CLI client provided by
the Debian linphone-nox package.
The idea behind this information is to allow remote
testing of an VOIP/SIP server with a headless computer,
to determine the cause of some problems, to find
if they are network/firewall related or more deeply in the 
build/configuration of the server program installation.

when using 
>soundcard use files

need to launch 'play ...file' soon after call begins,
seems to block, hunting for something to use for a microphone,
and will not even record, therefore:

>soundcard use files
>record <infile>
>call sip:..........
>play <outfile>
>.............

running the 'play' command ASAP after 'call'
see false bug report at:
http://lists.alioth.debian.org/pipermail/pkg-voip-maintainers/2009-May/013712.html


'play files'  should be 16bit pcm 8000Hz per
http://www.mail-archive.com/linphone-users@nongnu.org/msg01220.html

suggest making such files via:

ffmpeg -i sound.2.play.file    -ar 8000 -ac 1 -f wav     play.out.wav

seemed to work.
if no '-ac 1',  sound was at about 1/2 speed.
