'm usually using zrtp-encoded audio+video sessions from android-linphone
to android-linphone (in long-distance calls video sometimes gets stuck
on call setup though), and from pjsua-desktop-client which has the
abovementioned ZRTP implementation to android-linphone; but not managed
to establish a zrtp-session from anything to WP8-based linphone!

(Linphone didn't (or does not) announce anything zrtp-related during
session INVITE, so the other endpoint has to know about upcoming zrtp
content by other means.)

(Some time ago linphone-on-macosx while advertising supporting zrtp,
didn't support video-zrtp (or I simply didn't manage to get it to work),
and even didn't inform the user about not encoding video!  Haven't
tested again since then.)
