AFAIK Pidgin does not support ZRTP for VoIP, neither VoIP via SIP nor
VoIP via XMPP.
ZRTP implementations are available for the following RTP stacks
- PJSIP: implements ZRTP as a transport on top of the UDP transport.
PJSIP support "pluggable" transports. For example the Android CSipSimple
uses this implementation.
- a GStreamer plugin that can be put between UDP sources and RTP sinks.
No feedback about clients that use it currently.
- Implementation that links with GNU ccRTP (C++). Twinkle and SFL phone use
it, maybe others as well. Twinkle is a bit outdated, SFL project is active
Thus VoIP clients (SIP or XMPP) that use one of the above basic stacks can be
enhanced to use ZRTP. A good ZRTP implementation needs some GUI support, for example
to show some small security data to the user.
A Java implementation is also available, used by Jitsi for example.
