[Serusers] Registration - 401 Unauthorized

Hello, I`ve downloaded todays cvs and installed is, now, I am trying to register my SIP phone ( Snom 100 ), with it and authorize it. The phone sends a REGISTER and the ser sends it a 401 Unauthorized. ----------- 0.000000 172.20.0.199 -> 172.20.0.50 SIP Request: SUBSCRIBE sip:phila@phila.dg 0.002626 172.20.0.50 -> 172.20.0.199 SIP Status: 404 Not Found 0.038876 172.20.0.199 -> 172.20.0.50 SIP Request: REGISTER sip:phila.dg 0.042129 172.20.0.50 -> 172.20.0.199 SIP Status: 401 Unauthorized ------------- I`ve added the user to the mysql database and, am using the configuration included in the example ser.cfg ( I`ve uncommented the 4 lines). --------------------------- # Uncomment this if you want to use digest authentication if (!www_authorize("dg", "subscriber")) { www_challenge("dg", "0"); break; }; --------------------------- it seems that the www_challenge sends this message. How to fix this? And what is the SUBSCRIBE request? Thanks a lot, -- Anton Yurchenko<phila(a)dg.net.ua> Digital Generation
