Gnome-o-phone (gphone for short) is an internet telephone. In other words, if you and your friend have computers with sound cards and network connections, you can use gphone to talk to each other and save on phone bills. Gphone is definitely a work in progress and you probably shouldnt bet your business on it; if it breaks you can keep both pieces. Dont be too hard on the program, though -- the user interface is a bit rough but gphone does work pretty well.
As the name implies, it aims to be fully gnome-groovy, but that hasnt quite happened yet. Gphone is definitely a work in progress and you probably shouldnt bet your
business on it. Dont be too hard on the program, though -- although the user interface is mighty rough, gphone does actually work pretty well. Ive only tested the program over ethernet, but the data rate should be low enough to work over a reasonable modem connection.
The protocol is nominally RTP/RTCP, and gphone complies well enough with the standard to be able to talk to speakfreely. Ive only tested the UNIX version of speakfreely, but as long as you tell sfmike to use RTP and GSM compression, it seems to work fine. Maybe someday Ill add in support for other codecs; encryption is a little less likely
because Id just as soon not open that legal can of worms. One easy way to get some security would be to modify my program rtptunnel to tunnel the RTP protocol through a SSL socket instead of a straight TCP socket.
Gphone supports full duplex if your sound card has this feature. Ive had good luck using the ALSA drivers for my SB16.
Enhancements:
- gphone/gphone.c: Add Jorge Gomes Silvas patch to fix config button crash.

external IP shows your current external IP in the browsers statusbar.

External IP is set to check your IP address once every hour.

I Hear U is a Voice over IP (VoIP) application for Linux and it creates an audio stream between two computers in the easiest way and with the minimal traffic on the network.
I Hear U major features:
- Peer-to-Peer: the communication takes place between two computers without need of other servers and protocols in the middle.
- UDP/TCP support: IHU supports both UDP and TCP, with the possibility to choose UDP, for fast and easy connections, or TCP, if its the only solution when your computer is behind firewall or NAT.
- Good audio performance: IHU was born to give the best audio performance, low latency above all. For this purpose IHU is compatible with ALSA, now the default Linux sound architecture, but also with JACK, a low latency sound server. For the audio compression, IHU uses Speex, a codec optimized for speech (and completely free and open source).
- Crypted stream: you have also the possibility to crypt the stream using a fast hybrid cryptographic system (RSA + Blowfish)
- Command-line support: the GUI is not strictly necessary, you can run also a textual IHU from command-line (for example if you need to run the program on remote computers).
- Free and Open Source: IHU is totally free and distributed under the terms of GNU General Public License
The possibilities of use of IHU are infinite, for example you can use it like a phone to talk with your friends all around the world, or at home/work, to talk between computers in the LAN, etc., use it just as your phantasy suggests.
Main features:
- feature improved: ring volume adjustable
- bugfix: mute playback when seeking files
- source code: updated to speex 1.1.11
Enhancements:
- new feature: added possibility to convert IHU files to SPX file
- feature improved: quickly change port in the Receiver address using :
- feature improved: Defaults button in settings now affects only current tab
- feature improved: Volume Change speed for AGC changed to slider in the GUI
- bug fixed: TX dump file was closed after first call
- bug fixed: problems when playing files with different Speex modes
- bug fixed: conflict in the GUI when wating for calls and playing files
- source code: clear distinction in the use of h and hpp header
