Have you tested this change incorporated with libjitsi and in Jitsi Desktop? Do calls succeed with and without zrtp, sip and xmpp?

Thanks for your quick response! We've tested sip calls both with and without zrtp using our application, which was originally forked from Jitsi Desktop. To get this change to work with Jitsi Desktop, you'd need to update its version of BouncyCastle as well.
I don't quite understand what xmpp testing you're referring to - please could you clarify?

Xmpp audio/video calls. But if sip srtp calls work should be ok...

As far as I know, we don't support xmpp audio/video calls so that would be difficult for us to test.

@annatindall: Thanks a lot for your #3
But can you change to 1.65?

@Neustradamus Sorry, we don't have the testing budget to upgrade to 1.65 right now, but will take a look next time we update dependent libraries if ibauersachs doesn't get there first

@annatindall: Yes in first, it is possible to merge for 1.64 :)
@damencho, @ibauersachs: What do you think?

@ibauersachs: Solved?
