Hi Bernhard,

I performed the first proposal and got some 4kb of output.
I did not find any debug symbols for linphone yet in the standard
repositories, so there ar some complaints.

I did alter the phone number (2 places) and of course substituted my
paaswrd.

I do attach the output here, please advise whether I should try your
other proposals and/or install required debug symbols.

Kind regards,
Alf
