I don't follow "SRTP proper". If you mean "just SRTP without a key
management protocol" then this requires a UI at each end to input the
same key (and algorithm configuration, presumably). I have never seen
any VOIP program that could be configured that way.

I guess they could have tooltips with the longer versions. Maybe I'll
file a bug report.
