Hi Bogdan, better late then never ;) The upload of CPL scripts via SIP works fine with CPLEd but after changing the SER config file with the if statement you mentioned below I cannot REGISTER my client any more. It is a normal REGISTER without any payload in the SDP part. I try it with three different SIP clients and they all get a 500 error every time. Why do normal REGISTER messages run into the if statement, too? Many thanks for your help.

[Serusers] RE: Multiple Domain (kapil dhawan)

by kapil dhawan

Hi... i got the p[oint of using domain table i am already using it..that is to check for multiple domain verification only.....but for eg...if i add two users with username 111 with domain as a.com and b.com....it does in subscriber table with username as 111 and domains as a.com and b.com....this all is fine....when 111(a)a.com tries to call like 111#...what will happen...call only goes for last registration done...coz in location structure , it doesn't add the latest entry of 111(a)b.com.... whenever u make a call it searches for the first record in location table and call goes to it...so 111 a.com 111 b.com if the entries are like this....b.com can call a.com but not vice-versa... _________________________________________________________________ Play the prediction game on MEZ.

[Serusers] Unable to complete calls with 0.8.13

by Andres

Hi, I downloaded the latest CVS tarball and installed it in our lab. Using a LAN setup, where SER and 2 Sipura units are all in the same subnet, I am unable to complete any calls. All I can tell is that SER is unable to match the ACK to a current transaction. So when phone A makes a call to phone B and it answers, phone B sends the STATUS 200 OK back. Phone A then sends the ACK, but SER is unable to match it and is not forwarded to phone B. So the call is not completed. The syslog just shows a bunch of these messages: Warning: sl_send_reply: I won't send a reply for ACK!! I have tried this under RedHat 7.3 and Solaris 8 with the exact same results. I can send the Ethereal Trace of this event to whoever can help me. The config file is extremely simple (listed below). Any clues of what is going on? Thanks. -- Andres Network Admin http://www.telesip.net 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; }; # we record-route all messages -- to make sure that # subsequent messages will go through our proxy; that's # particularly good if upstream and downstream entities # use different transport protocol record_route(); # loose-route processing if (loose_route()) { t_relay(); break; }; # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (uri==myself) { if (method=="REGISTER") { save("location"); break; }; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; # forward to current uri now; use stateful forwarding; that # works reliably even if we forward from TCP to UDP if (!t_relay()) { sl_reply_error(); }; } -- Andres Network Admin http://www.telesip.net

[Serusers] failure route and ERROR: t_should_relay: status rewrite by UAS: stored: 408, received: 487

by Alan Crosswell

I'm trying to do failure route to voicemail (which is working) but this error is logged: ERROR: t_should_relay: status rewrite by UAS: stored: 408, received: 487 I googled this and see that this came up last in October (http://lists.iptel.org/pipermail/serusers/2003-October/002921.html) but I don't see any evidence of a solution in the thread. I suspect mine is the same problem as I have two UAs registered so the initial dset is two places and then the append_branch on timeout is just the voicemail uri. BTW, I am doing this with asterisk for the usual DTMF access reasons (altough I haven't yet figured out how to map sip:alan@columbia.edu to DTMF. Maybe I'll have to give up and do numeric mailboxes:-( I am rewriting with a prefix of "vm*u" before punting over to asterisk which has exten => _vm*u.,1,Wait,1 exten => _vm*u.,2,Voicemail(${EXTEN:3}) exten => _vm*u.,3,Goto(#,1) Any pointers would be appreciated. My not-yet-complete ser.cfg is attached (not yet punting voicemail for unregistered subscribers; just registered subscribers who time out the invite). /a # # $Id: ser.cfg,v 1.21.2.1 2003/07/30 16:46:18 andrei Exp $ # # simple quick-start config script # # ----------- global configuration parameters ------------------------ debug=2 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) #listen=128.59.39.127 check_via=yes # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) port=5060 children=4 fifo="/tmp/ser_fifo" alias="columbia.edu" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/acc.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" # Uncomment this if you want digest authentication # mysql.so must be loaded !
