According to your logs, it seems that the remote peer does not offer server reflexive address. I believe you and your friend are not in the same LAN so there may be a problem on your friend configuration.
Does he use Jitsi ?
If yes be sure he has check (in ICE configuration of the account) "Auto discover STUN/TURN servers" and "Use jitsi's STUN server in case no other servers are available". You could also check "Use UPnP". Having the logs of your friend may also help us to track the problem.

again we tried to establish a call and it failed with the exact same
error. We both used Jitsi downloaded last Friday. I uploaded the logs:
Any idea how to solve the problem? Thanks!
When calling to call a friend via Jabber, the following error occurs:
error: could not establish connection (ICE failed)
As the error messages states, the call couldn't be established.
How to find out the root cause of this problem and how to solve the problem?
