Thank you Mr.Smith,
for your kind and prompt reply and suggestions.
However, if possible, we would prefer not to ask our users subscribe to
yet another service. From the same account to the riseup.net server we
would at once get encrypted secure email and XMPP service.
It should work and it did work at least twice... we are still hoping to
solve this and hopefully we will get some instructions from the Jitsi
Best regards, Betta

Subject: Re: [jitsi-users] ICE-Failure error when trying to place
voice calls using the Riseup.net XMPP server and Jitsi as a client
Content-Type: text/plain; charset="utf-8"
probably the Jitsi developers will suggest this, too:
the explanation for the "ICE-failure" you will find here:
thus try the XMPP server of the Jitsi team, which should avoid these
alternative you can also use (as described and recommended in the FAQs
above) the SIP provider IPPI (www.ippi.com) - free registration and usage.
As Jitsi supports also now OTR for chats using SIP protocol, you already
have two possibilities for testing all scenarios.
As Jitsi uses both OTR and zRTP for end-to-end encryption the server
maintainer cannot access the content of you communication
hope this helps!
best greetings, MS
