Hi Jens,
can you capture the request that trigger the error? (the second INVITE,
after challenge). I can take a look to see what is the problem.
if you configure the credentials into the phone, a reason for the phone
not to respond to authentication is that it was not able to match any
local credentials against the received challenge - based on username and
realm).

Hello list,
i have following code in my openser configuration to prevent that
everybody can make calls to PSTN:
process INVITE messages
-- snip
if( !allow_trusted() ) {
if( !proxy_authorize( "myrealm", "subscriber" ) ) {
proxy_challenge( "realm", "1" );
return;
} else if ( !check_from() ) {
sl_send_reply( "403", "Use From=ID" );
return;
};
consume_credentials();
};
-- snap
This works fine with snom200, snom360 and some other phones/ATA.
It isn't working with Linksys IPPhone SPA941, snom100 and the ATA
Linksys SPA 2001.
All these three devices aren't sending the credentials after they are
challenge to send them. I know this because the new INVITE message have
no digest information in it, the call isn't be placed and the following
error message from the logs of OpenSER:
/sbin/openser[3323]: find_credentials(): Error while parsing headers
I have also tried that the second parameter of proxy_challenge are 0
(zero) but that didn't helped.
Have anybody a clue where I can change this behaviour of the three
devices? Have I change some settings, etc of the phones/ATA?
Or maybe I have to change my code for the OpenSER? But I will avoid this
because I don't want to be an open relay.
Thanks in advance
Jens
