Description: IHU is a Voice over IP (VoIP) application for Linux, that creates an audio stream between two computers easily and with the minimal traffic on the network.
The main features are:
* Peer-to-Peer: the communication takes place directly between the computers (UDP and TCP both supported), without need of session protocols (such as SIP or H323) or other servers in the middle.
* 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 Encrypt/Decrypt the stream using a fast hybrid cryptographic system (RSA + Blowfish)
* Command-line support: the Qt 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 endless, 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 (talkback), etc.Last changelog:
# IHU v. 0.6.0
- new feature: multiple calls now allowed (full conference not yet supported) - feature improved: AGC moved from player to recorder (with mixer support) - feature improved: sound input level added to GUI - feature improved: TX threshold and AGC volume converted to dB - feature improved: file player/converter in a standalone dialog - feature improved: .spx file converter now faster - feature improved: config file entirely reviewed, now it's possible to specify the file - feature improved: now it's possibile to save the passphrase in the config - feature improved: some improvements in the tray icons - feature removed: JACK driver for output has been disabled - bug fix: no more problems with XRUN handling for ALSA player - source code: IHU architecture totally reviewed, GUI made independent from Phone
Development seems to have stopped :(
Hopefully someone can take over this fantastic app?!
Anyway there are not much apps in the "telephony" group, most of them not actuall and even twinkle is not based on Qt4 yet,... It's annoying!!!
Yours Programm is very good. I like it. It is now in Gentoo Overlays VoIP.
Could You implement higher Ports, such as 65000, please?
And perhaps a Choise, for Mono or Stereo Speex Codecs.

A better Security, I am paranoic, Choise for a Random Keys with constant
Lenghts (bits) greater as 448, 4096 the Best.
Capabillity to write the Names in the full UTF-8 Letter, such as
čćžšđ, чћжшђ don't work
öä$ü works
Thanks smartnow
Add dcop support and some kind of event handling or at least knotify integration and it will be perfect... No, just let me add one thing... Zeroconf integration would be great too, so you could fill the dropdown box with possible participants automatically.
Are there any plans to add webcam video? If you would plan that I would be the happiest person ever :)
I don't know how complicated it would be to port this to windows but it's worth a look. This could get an alternative to skype if done right (of course that would be a longer journey then :) )
I'll look into the code and check what has to be done to get it to compile on windows, I'll contact you if I know more ;)
Thank you for your suggestions. I found interesting DCOP and Zeroconf integration.
Instead I think that I won't add webcam support for the moment, maybe in the future.
Please contact me if you're interested in the port to Windows!
Yeah i heard there's a windows effort to port KDE libraries etc to windows.
We want to avoid KDE3 dependencies like DCOP thanks. Eventually KDE3 won't be supported anymore.
Dear Mr Trotta:
Is there any possibility to port ihu for the maemo platform so that it would be available for Nokia 770 device, which runs on a Debian system over an armel chip?
Thanks in advance.
Regards,
Sebastian.
PD: I would help in any way as much as possible.
Hai
Iam a beginner..I installed ihu and when I tried running it I got the following error message at the terminal
"ihu: error while loading shared libraries: libSoundTouch.so.0: cannot open shared object file: No such file or directory"
How can this be fixed?
You need to install the soundtouch libraries (http://www.surina.net/soundtouch/). I think you can find ready packages for your distribution, but you can also compile the sources.
No, IHU works only for two computers. Maybe you can try some tricks to connect the 11 computers with IHU, for example using 11 instances of IHU and call each computer on each different one. But it's not so practical.
The answer is no. At the moment IHU avoids the use of external servers, even if this reduces its usability.
Anyway in the future I may add STUN support as optional feature.
Yes, IHU will work if only one computer is NATed, but the NATed computer will be able just to make calls, not to receive calls.
Unfortunately I don't have time to work on a Windows port now. Any help is welcome.

And could You add a Speaker device for ringing, please. As Twinkle. Regards Smartnow

Why dcop? The future is dbus as even kde4 will use it and not dcop anymore. Nice would be to use phonon. AFAIK phonon will work on windows too

Its only possible with Two computers? or i could use more? Because i need to connect a total a 11 Workstation for a class room. Thanks

Hi, are there any techniques included to establish a connection between two NATed computers like STUN etc.? Thank you! M
The answer is no. At the moment IHU avoids the use of external servers, even if this reduces its usability. Anyway in the future I may add STUN support as optional feature.
Thank you for your answer.
And what if only one computer is NATed? Does it work then? And another question - are you going to prepare a version of IHU for Windows?
Yes, IHU will work if only one computer is NATed, but the NATed computer will be able just to make calls, not to receive calls. Unfortunately I don't have time to work on a Windows port now. Any help is welcome.
