gphone is a net phone base on the rtp protocol. It is simple but pratical and can be a good sample f

Gphone 0.5.2   (August 18, 2000)
============

Incorporated Jorge Gomes Silva's patch to fix the infamous config
button crash.  This is only a only-line difference from 0.5.2.

Gphone 0.5.1   (January 5, 2000)
============

Incorporated Carlos Puchol's patches to work with the new free
Quicknet drivers.  Fixed a bug with calculating the mic and speaker
level.  Check for gsm.h and slang.h in both the Redhat and Debian
locations.

Gphone 0.5     (December 12, 1999)
==========

Added a rudimentary configuration dialog so you don't have to set up
everything from the command line.  Also added some support for
Quicknet Technologies Internet PhoneJACK card.  Right now it can only
be used as a sound card; a future release should let you use the
spiffy codecs built into the card.  There's also a new call button in
the window, but it's always disabled because there's no code to hook
it up to.

Gphone 0.4     (December 4, 1999)
==========

The RTP protocol code has been completely rewritten and cleaned up.
There is better separation of the various layers, which should make it
easier to add features in the future.  In particular, the "switch"
button should work in half duplex mode now (it uses the new RTP code
to send APP packets).

I also added primitive silence suppression; right now, to change the
threshold you have to edit talk.c.  I got rid of the -q option and
added a verbose option, -v.  The default is now not to print tons of
messages when nothing is wrong.  There's a -t option to read sound
from a file (raw signed 16-bit 8Khz samples) instead of the
microphone.  This is useful when running more than one gphone at a
time to debug.

Gphone 0.3     (November 9, 1999)
==========

The sound code got rewritten to open /dev/dsp only once.  Full duplex
should work with OSS drivers that support it. Also added a .spec file
from Lyle Kempler to support building RPMs.  Added a -q option to
suppress the debugging messages.

Gphone 0.2.2   (October 17, 1999)
============

Merge in Eric Gaudet's prettier error messages and change all the tabs 
to spaces to make editing on different setups easier.

Gphone 0.2.1   (October 16, 1999)
============

Minor cleanups only in this release.  The biggest thing is adding a
flag in connection.c to keep track of the fact that we placed the
call.  This lets half-duplex work better because the first incoming
RTCP packet doesn't make the caller switch from talking to listening.

Gphone 0.2     (September 14, 1999)
==========

I've rewritten a significant portion of the program.  The most
significant change is that I've switched to the standard RTP protocol
(RFC 1889 & 1890) over UDP instead of my own screwy TCP protocol.
I've also gotten rid of the ringer and the daemon, and changed how the
threads interact a bit.  You might notice that the quit button works
now too.  Half duplex is broken at the moment.

Gphone 0.1     (May 22, 1999)
==========

This is a developer release; the basic functionality is there but the
user interface is a tad shaky. Most of my effort went into the TODO
file for this release, so if you want to start hacking, I have plenty
of suggestions.  But you should feel free to work on whatever is most
important to you.
