[jitsi-users] ICE-Failure error when trying to place voice calls using the Riseup.net XMPP server and Jitsi as a client


#1

Hi,

PROBLEM
we were not able to speak to one another via Jitsi because of repeated
errors: ICE-Failure was the basic message.

SETTING
- 3 users, call them A,B and D. All on the internet from Bolivia, Italy and
USA.
- All with Jitsi and XMPP accounts on riseup.net.
- We had successful chats with OTR and authentication between all pairs of
users: A with B, B with D, and D with A.
- Also B invited A to conversation between B and D creating a chat room on
separate window where we could all chat together (although we still have to
figure out the best procedure for starting a group chat)

BUT
- several times we attempted voice calls to one another in all possible
combinations and directions: A tried calling B, B tried calling A, A tried
calling D, D tried tried calling A, B tried calling D and D tried calling A
- every time the Jitsi phone rang, but the call immediately failed with a
message that flashed briefly (and did not remain on screen) but spoke of
ICE-Failure error
- please note that previously in two different occasions (January 8th and
January 16th) the users B and D had successfully managed to speak with each
other without any error messages - but this time it did not want to work.

WHAT IS THE PROBLEM AND WHAT CAN BE DONE?

BACKGROUND INFORMATION
Our Organization [Initiative for Equality (IfE)
https://www.initiativeforequality.org/] is an international network of
activists, academics and grassroots organisations working with a holistic
approach on issues of inequality. We are currently searching for secure
online tools to support cooperation and communication of our members who
are spread out around the world.

In particular we are trying to see if we can replace Skype (which is not
secure at all, but it is rather easy to use) for our voice group meetings (+
text chat room).

Following the advice by Security in a Box [https://securityinabox.org/jitsi]
we decided to give Jitsi a try. We do not have the technical resources to
manage our own server and decided to rely on the riseup.net XMPP server run
by a collective which we feel we can trust and which we want to use also
for secure encrypted email service.

Our initial testing worked perfectly well: two of us managed to text and
speak securely to each other. But, two days ago, on February 11th 2015, for
our first test involving a group of 3 people, we were totally unable to
communicate with voice. We successfully established pairwise text OTR
conversations as well as created one collective chat room which the three
of us were able to join and in which we managed to chat as a group.

But every time we tried to call each other to speak, we got an error
message "ICE-Failed or something...".

In order to test a group voice conference, we wanted to start from a
one-to-one conversation to which we intended to later invite the third
person. However, independently of who was calling whom, we never managed to
successfully establish a voice call, even just one-to-one. We got the call
ringing, but it resulted in immediate unsuccessful attempt, with an error
message something like ICE-Failed etc.

Do you know what it means and what can be done about this? Does it depend
on the Riseup server, or on Jitsi, or on the compatibility between the two?

As far as we can see (and understand) the setup should work, Riseup claims
to support Jingle and although Jitsi is not among their top recommended
clients it does appear on their list [
https://help.riseup.net/it/chat/clients#other-clients, and they acknowledge
that Jitsi is the one client which supports encrypted voice and video
communication https://help.riseup.net/it/chat/chat-security]

Do you know what may be the problem?
Do you have any suggestion on what we can try to solve this error?

We need to establish a procedure that can be reliable every time we need to
communicate.

And we need to teach a broad base of users widely spread around the world
with varied types of computer setups and not very tech-skilled.

Thank you in advance for your support,

Best regards, Betta Rossi (IfE)

Hallo Elisabetta,
probably the Jitsi developers will suggest this, too:

the explanation for the "ICE-failure" you will find here:
https://jitsi.org/Documentation/FAQ#ice-failed

thus try the XMPP server of the Jitsi team, which should avoid these
problems:
https://jitsi.org/index.php/Register/Register

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
