I have installed and configured Asterisk and that's working without problems in static mode. To use Realtime, i have created a table (sipuser) and put this line in extconfig.conf sipusers => mysql,asterisk,sipuser The connection to the database is alive. bechtoldsheim*CLI> realtime mysql status Connected to asterisk@davenport.*.*.*, port 3306 with username asterisk for 10 minutes, 34 seconds. 2006-09-18 14:36:25 DEBUG[23680]: res_config_mysql.c:674 mysql_reconnect: MySQL RealTime: Everything is fine. There is one record in the table sipuser, with the name 'edwin'. name edwin context edwin host dynamic type friend deny 0.0.0.0/0.0.0.0 permit 10.0.0.37/255.255.255.255 But when i try to register the sipuser 'edwin' with kphone (KDE SIP phone), the following error is shown in the Asterisk log. 2006-09-18 14:34:43 NOTICE[23672]: chan_sip.c:11084 handle_request_register: Registration from '"Edwin Pauli" <sip:Edwin@bechtoldsheim.*.*.*>' failed for '10.0.0.37' - Username/auth name mismatch This information is in sip.conf (the same as what i have insert into the database).
