Thanks for answer, I have repaired my configuration and now I can connect to SER server. But I have problem with digest authentication. I have created test domain "ipt", SIP_DOMAIN variable is set to "debtest.ipt". When I try to login as my test user &quot;abc(a)debtest.ipt&quot; with passwd "abc" I got 401 Unauthorized. (I'm using Windows messenger 4.6) Here is my ser.cfg file: -------------------------------------------------------------------- log_stderror=no # (cmd line: -E) debug=3 fork=yes listen=10.1.22.237 listen=127.0.0.1 check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) fifo="/tmp/ser_fifo" loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/sl.so" loadmodule "/usr/lib/ser/modules/tm.so" loadmodule "/usr/lib/ser/modules/rr.so" loadmodule "/usr/lib/ser/modules/maxfwd.so" loadmodule "/usr/lib/ser/modules/usrloc.so" loadmodule "/usr/lib/ser/modules/registrar.so" loadmodule "/usr/lib/ser/modules/auth.so" loadmodule "/usr/lib/ser/modules/auth_db.so" modparam("usrloc", "db_mode", 2) modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "password_column", "password") modparam("rr", "enable_full_lr", 1) # main routing logic route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); break; }; record_route(); # loose-route processing if (loose_route()) { t_relay(); break; }; if (uri==myself) { if (method=="REGISTER") { if (!www_authorize("debtest.ipt", "subscriber")) { www_challenge("debtest.ipt", "0"); break; }; save("location"); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; if (!t_relay()) { sl_reply_error(); }; } -------------------------------------------------------------------- And here is output from ngrep: -------------------------------------------------------------------- # U 10.1.22.235:1603 -> 10.1.22.237:5060 REGISTER sip:debtest.ipt SIP/2.0..Via: SIP/2.0/UDP 10.1.22.235:7455..Max-Fo rwards: 70..From: <sip:abc@debtest.ipt>;tag=dcdbd44febe84f4696edd53145a3d53 9;epid=0f021563db..To: <sip:abc@debtest.ipt>..Call-ID: 6236b0275a2940cc8ce3 a1001f3bdf3a@10.1.22.235..CSeq: 1 REGISTER..Contact: <sip:10.1.22.235:7455> ;methods="INVITE, MESSAGE, INFO, SUBSCRIBE, OPTIONS, BYE, CANCEL, NOTIFY, A CK, REFER"..User-Agent: RTC/1.2.4949..Event: registration..Allow-Events: pr esence..Content-Length: 0.... # U 10.1.22.237:5060 -> 10.1.22.235:7455 SIP/2.0 401 Unauthorized..Via: SIP/2.0/UDP 10.1.22.235:7455..From: <sip:abc @debtest.ipt>;tag=dcdbd44febe84f4696edd53145a3d539;epid=0f021563db..To: <si p:abc@debtest.ipt>;tag=33a7c77b78ad137e35158c65143a88ce.c46c..Call-ID: 6236 b0275a2940cc8ce3a1001f3bdf3a@10.1.22.235..CSeq: 1 REGISTER..WWW-Authenticat e: Digest realm="debtest.ipt", nonce="402b702efe807eba708cf8f1cc71dd66b35ec 80e"..Server: Sip EXpress router (0.8.12 (i386/linux))..Content-Length: 0..
