[jitsi-users] encrypted


#1

hello good morning, I have some doubts about jipsi, I hope you can help me.
Jipsi encrypts default video calls?
I have to configure something to encrypt video calls?
sender and receiver must have installed jippsi to encrypt video calls?
any account you use to encrypt chats and video calls jippsi?
thank you!


#2

I also tried Jitsi Video Call, and it says "severe ZRTP problem", so call went unencrypted. Why this happens? Anyone can suggest SIP or XMPP server around the globe that have sufficient bandwidth to handle encrypted jitsi video calls?

Btw, do encrypted calls require more bandwidth? Can one's internet provider block ZRTP protocol altogether? Anyone can suggest, how to actually achieve call encryption as opposed to have this feature "available" but not working for ordinary users?

Hello,

hello good morning, I have some doubts about jipsi, I hope you can help me.
Jipsi encrypts default video calls?

By default it tries to. There is a padlock button that indicates the current status.

See more here:

I have to configure something to encrypt video calls?

No. But as people already mentioned, if you are using SIP, your provider might be preventing ZRTP from working.

sender and receiver must have installed jippsi to encrypt video calls?

No, but they both need to support ZRTP.

Regards,
Boris

Hi,

The video calls and audio calls are encrypted by default. Both parties
needs to support ZRTP. ZRTP is not possible with some SIP servers like
asterisk as the media goes through the server. If xmpp call is
possible, ZRTP should be enabled, no matter of the server. With other
words, I'm not aware of an xmpp that can block the ZRTP.
There is no change in the bandwidth when using encryption, if there is
any it won't be noticed by the user.
Hope this helps.

Доброго времени суток, Zamar.

Yes, SIP providers can block ZRTP protocol.
Ask your provider's support.

Boris has already replied and I don't mean to be rude, but the software is
called Jitsi. The least thing to do is at least write the name correctly.
Once again I mean no offence, but it's a really small effort to show
respect to the project by simply.. writing the name correctly. :slight_smile:

Thanks,

I found this thread (http://lists.jitsi.org/pipermail/dev/2012-January/001525.html), where the guys say that due to Jitsi ZRTP implementation limitations, to achieve video session encryption, both parties using Jitsi must first establish audio only session, and once it confirms on-screen ZRTP working, then switch to video session. Is that still true today? Do you recommend that approach?

Any way to independently verify, if a certain provider blocks ZRTP, without contacting that provider, since they may deny blocking anyway?
