Hi all, I have had some success with the configuration, however using authentication does not work for me at all. I have grabbed another cfg for testing, I can see my ata sending reg requests to the server and the server just replying immediately with unauthorized 401 error. Shouldn't the server first reply with a 100 trying message? Does the cfg file look like it should work? Thanks again, 64.189.165.2065060 -> 64.189.165.2055060 REGISTER sip:sip.coptalk.com SIP/2.0..Via SIP/2.0/UDP 64.189.165.2065060..From sip:Rick@sip.coptalk.com;tag=21094236 64..To sip:Rick@sip.coptalk.com..Call-ID 399581690@64.189.165.206..CSeq 1 REGISTER..Contact <sip:Rick@64.189.165.206 5060;transport=udp>;expires=3600..User-Agent Cisco ATA 186 v2.16.2 ata18x (030909a)..Content-Length 0.... # U 64.189.165.2055060 -> 64.189.165.2065060 SIP/2.0 401 Unauthorized..Via SIP/2.0/UDP 64.189.165.2065060..From sip:Rick@sip.coptalk.com;tag=2109423664..To sip:R ick@sip.coptalk.com;tag=b27e1a1d33761e85846fc98f5f3a7e58.4a60..Call-ID 399581690@64.189.165.206..CSeq 1 REGISTER..WWW- Authenticate Digest realm="sip.coptalk.com", nonce="3fd602692d1f0bf922ae277c623f1d201acbde03"..Server Sip EXpress rou ter (0.8.12 (i386/linux))..Content-Length 0.... # ----------- global configuration parameters ------------------------ debug=3 # debug level (cmd line -dddddddddd) fork=yes log_stderror=yes # (cmd line -E) #/* Uncomment these lines to enter debugging mode #fork=no #log_stderror=yes #*/ check_via=no # (cmd. line -v) dns=no # (cmd. line -r) rev_dns=no # (cmd. line -R) port=5060 children=4 fifo="/tmp/ser_fifo" # # $Id pstn.cfg,v 1.2 2003/06/03 031812 jiri Exp $ # # # ------------------ module loading ---------------------------------- loadmodule "/usr/lib/ser/modules/tm.so" loadmodule "/usr/lib/ser/modules/sl.so" loadmodule "/usr/lib/ser/modules/acc.so" loadmodule "/usr/lib/ser/modules/rr.so" loadmodule "/usr/lib/ser/modules/usrloc.so" loadmodule "/usr/lib/ser/modules/uri.so" loadmodule "/usr/lib/ser/modules/registrar.so" loadmodule "/usr/lib/ser/modules/maxfwd.so" loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/auth.so" loadmodule "/usr/lib/ser/modules/auth_db.so" loadmodule "/usr/lib/ser/modules/textops.so" loadmodule "/usr/lib/ser/modules/group.so" modparam("auth_db", "db_url","sql//password@localhost/ser") modparam("usrloc", "db_url", "sql//password@localhost/ser") # ----------------- setting module-specific parameters --------------- modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "password_column", "password") modparam("usrloc", "db_mode", 2) # -- acc params -- # modparam("acc", "log_level", 1) # that is the flag for which we will account -- don't forget to # set the same one -) # modparam("acc", "log_flag", 1 ) # ------------------------- request routing logic ------------------- # main routing logic alias="coptalk.com" alias="sip.coptalk.com" use sip_warning=no modparam("rr", "enable_full_lr", 1) route{ # initial sanity checks -- messages with # max_forwards==0, or excessively longrequests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if (msglen >= max_len ) { sl_send_reply("513", "Message too big"); break; }; # we record-route all messages -- to make surethat # subsequent messages will go through ourproxy; that's # particularly good if upstream and downstreamentities # use different transport protocol record_route(); # loose-route processing if (loose_route()) { t_relay(); break; }; # if the request is for other domain useUsrLoc # (in case, it does not work, use thefollowing command # with proper names and addresses in it) if (uri=~&quot;[(a)\.]sip\.coptalk\.com([;].*)*&quot;) { if (method=="REGISTER") { # Uncomment this if you want to use digestauthentication if (!www_authorize("sip.coptalk.com", "subscriber")) { www_challenge("sip.coptalk.com", "0"); break; }; save("location"); break; }; # native SIP destinations are handledusing our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "NotFound"); break; }; }; # forward to current uri now; use statefulforwarding; that # works reliably even if we forward from TCPto UDP if (!t_relay()) { sl_reply_error(); }; if (uri=~"^sip[0-9]*@.*") { log("Forwarding to PSTN\n"); t_relay_to_udp ("65.189.155.101","5060"); t_relay_to_tcp ("65.189.155.101","5060"); break; }; if (method=="INVITE") { sl_send_reply("403", "Call cannot be served here"); } else { forward(urihost, uriport); }; break; }
