GNU SIP Witch and Antisipate

Generally I avoid doing gui projects, simply because every gui I ever attempted ended up looking very ugly. Yet, a little over a month ago I decided we needed to develop a true GNU Free Call desktop & mobile client of our own to work with our SIP Witch servers, even with what limited resources we had. This package is now being called Antisipate.

Thanks to the widespread adoption of GNU ZRTP (libzrtpcpp), including it’s use in ortp, there is actually no shortage of ZRTP enabled clients in general, including linphone, sflphone, and even Kopete. The Java version of our library, as maintained by Werner Ditterman, ZRTP4J, became part of Jitsi. However, none of these offered a very simple to configure SIP client, which really is an essential part of our goal for replacing Skype with free software that is easy to use and operate by anyone, and that uses standard protocols. Hence, Antisipate.

Our overall goals also includes delivering VoIP socially, through integration with Friendica, as well as making it possible to use stand-alone SIP services and our new Antisipate client. For IVR support we will be introducing a new and more modern version of Bayonne.

Our greatest challenges remain not the technical, nor even with available volunteers, but rather with things like funding. Our development has become very resource bound. I am very grateful to Andrew Doughty for making available a publicly accessible development server for our use some months back. I plan to publish much more regular updates on our work going forward.

    Given the amount of pain it is to setup even a single secure VoIP call and the fact that most SIP servers/clients tend not to take encryption very seriously, I look forward to what comes out of this project.

    You mention funding – does there exist some sort of donation page for GNU Telephony?

    Gnu telephony.
    Malepile.is are going to built a gpg supporting email client, that has greater usability. Now I am not sure, that what is holding the majority back from using gpg email is, that setting up gpg is to complicated. Rather it is the absence of awareness about email privacy, or privacy does not matter. But for those aware and wanting to get email privacy, it is good that mailpile makes it easier not to get stuck in technical matters.
    I believe the situation is the same about telephony. Most are not aware or disregard the subject. But for the rest privacy solutions are important. And the better usability, the more can get to use an application. Therefore your project is great.
    Right now the public do not know how much, what or whom is getting their electronic communication recorded. But the media are giving some clues.
    I experienced, that getting gpg email was not easy, but it was not difficult either. Once you find the applications and grasp the structure of key management, it is manageable.
    About encrypted sip softphones it has been difficult getting anything running. My system is ubuntu 12.04. I have tried twinkle and now sflphone and linphone. Cannot get anything of it to work. Error messages one after another. All this can be caused by my system or likely my skills. I cannot determine. Only sip softphone I partly got running is jitsi. Often voice works, messages and video never. To accomplish that, I had to find out that my internet provider had to make some setting, I opened about 5 different sip accounts, only 1 works. All in all not great.
    If gnu telephoney can make something more approachable and explanatory, that would be welcomed.
    I put privacy over appearance and features. If I am out for encrypted telephony, I have already decided what comes first. I do not care about the gui. I accept fewer features. What I want is an application I can get to work, and that those who code know what they are doing and give me the privacy they say they will.
    On indiegogo mailpile wanted 100000usd, and got more. Why do you not consider a crowd funding, and do you want that much?
    And http://tox.im/ what technology are they using?

    I thought I would address these questions directly in a new post, http://planet.gnu.org/gnutelephony/?p=73
