Hey Alexei,

I'm a regular user of your very nice Telephone.app.  I'm currently
working with Guardian Project, and we are looking for a SIP app that
works well and also supports ZRTP secure communications.  We are also
working with csipsimple on Android, which is also based on pjsip.

I have updated Telephone.app to support SIP/TLS, and that is working
well.  https://github.com/eighthave/Telephone  Next, I would like to
update Telephone.app to support ZRTP just like csipsimple does.  The
bulk of this work needs to happen in the pjsip build, but there also
needs to be a minimal UI work.

For ZRTP, there needs to be some notification:

* show whether ZRTP is in use
* show whether the ZRTP session is verified
* show the four letter verification code

That is all the UI that is needed.  So the question is now, how to
approach this work?
