Hi @ all, I tried to get the UAC module working on a asterisk but still without luck and saw some "necessary" improvements for UAC-Reg. If there is somewhere a "wish-list" I could add that there: 1. if the registration is not successful the first time, Kamailio will never try it again. 2. if the authentication is not successful, Kamailio will send the registration for authentication again and again for about 100times a second. 3. UAC-reg "reload" command for kamctl Best regards, Bernhard
