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 Twinkle is a bit outdated, SFL project is active and supported. 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. > Can you help me? > > _______________________________________________ > [email protected] mailing list > Want to unsubscribe?
