We have our own sip / xmpp server and we have compiled the latest build of csipsimple and Linphone.
We want a secured voice over zrtp. This is a peer to peer encryption but i dont get it work, not under csipsimple and not under Linphone.
I need support to get this work.
Linphone and csipsimple can be downloaded on playstore.
We already had done something like this before As i saw your project description i can assure you that your project will be completed on time.
