Hi Andrew,
problem solved. I changed the outbound CID in t38modem to match the subscriber ID in Kamailio and now the authentication succeeds and the calls pass through.
Thanks a lot for sending me on the right path and your valuable time.
Cheers, Carsten.

It looks like the challenge is generated by the config line 721 - could you post somewhere what is in there (or your whole config)?
5(31487) DEBUG: auth [api.c:218]: check_response: Authorization is OK [...] 5(31487) ERROR: *** cfgtrace: c=[//etc/kamailio/kamailio.cfg] l=721 a=27 n=auth_challenge
if I comment out the offending code block around line 721
# authenticate requests if (!auth_check("$fd", "subscriber", "1")) { auth_challenge("$fd", "0"); exit; }the call indeed passes through.
What I learned from
http://kamailio.org/dokuwiki/doku.php/pseudovariables:3.1.x
the pseudo-variable $fd references to domain in URI of 'From' header, which in this case is
From: "root" sip:030123456789@10.1.1.148:5123
Does this mean, the authentication is rejected because the domain part of the URI is identical to the one from Kamailio?
Or does it mean, the authentication is rejected because the local part 030123456789 in URI does not match the subscriber 979?
Greetings, Carsten.
