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
