[Serusers] Help rewriting "To" URI
by José Nunes 26 Nov '03

26 Nov '03

Hello, I've been working whit SER for a while, and I need to have some way of redirecting Invites dynamicly. The idea is similar to the definition of groups (local,ld,...), only I want to be able to define the redirection address without having to rewrite ser.cfg (and therefor reinitialize SER). The part of defining these new groups and addresses was straightforward, after that I tried to build a module that would have a function to do the writing of the "To" URI. The only function I found to alter the destination URI was append_branch. The module compiles without error and SER works normally, except it does not do the redirections that I was hoping. Are there any other ways of adding/rewriting something to the body of "To" in the SIP message? Or one can only do that in ser.cfg? Thanks in advance, José Nunes

[Serusers] ser route config problem again
by xwang＠novsky.com 26 Nov '03

26 Nov '03

sorry for again and again because my mail seems to be unreadable Pls help me to config ser.cfg Now my envirmonet is: ser server: 172.16.255.1:5060 ( without DNS server ) SIP PSTN gateway: 172.16.255.1:6050 SIP UA: 172.16.2.xx And all SIP UAs have a PSTN number like 6169xxxx There are no DNS server in the system.(we don't apply for a domain name) I want: 1 All users use digest authorization when SIP UA registing ------ finished 2 All calls from SIP UA need authorization (return 407 to Invite request) 3 All calls to PSTN transfer to the SIP PSTN gateway(number no like "6169xxxx") -------- almost finished 3 All calls from the SIP PSTN gateway do not need authorization(I think use a caller sip:gateway@172.16.255.1:6050 as caller when call from gateway,then all call from this user and this ip address needn't authorazation) 4 All calls need write CDR record to mysq datebase The bigest problem is I don't know how to write conditonal sentence , like if(uri!=~"xxxx") or if((uri=="xxxx") | (uri=="yyyy")) There are no document talking about the syntax. Please help me. Any help is appreciate.

[Serusers] Ser CDRs
by Gregory D. Burns 26 Nov '03

26 Nov '03

Guys, Im new with ser, but it seem great so far. The customer Im working with want to get reliable CDRs from his SER SIP Server. He also has pre-paid customers on it so it need to check to see if they have monies to make the call, and when the call is done, it need to calculate and deduct the cost of the call from their balance. I have been using exec_msg command to try and do this, but I been having a hard time getting it to work right because I get more then one invites and acks. Also sometime they miss-dial and I only get Invites. So I guess my is, are exec_msgs the right way to go? Is anyone else doing the same thing, if so could you share you config with me? -Greg Voipin.com # # $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=4 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) /* Uncomment these lines to enter debugging mode debug=7 fork=yes 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" mhomed=yes # ------------------ module loading ---------------------------------- loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" loadmodule "/usr/local/lib/ser/modules/exec.so" loadmodule "/usr/local/lib/ser/modules/mysql.so" loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/textops.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" loadmodule "/usr/local/lib/ser/modules/uri.so" #loadmodule "/usr/local/lib/ser/modules/group.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- modparam("usrloc","db_mode",2) modparam("usrloc", "timer_interval", 30) modparam("usrloc","db_url", "sql://ser:dc74uc@localhost/Tigris") # -- auth params -- modparam("auth_db", "db_url", "sql://ser:dc74uc@localhost/Tigris") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- # main routing logic route{ /* ********* ROUTINE CHECKS ********************************** */ # Take take of Max hops if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; # Too big for a SIP msg. if (len_gt( max_len )) { sl_send_reply("513", "Message too big"); break; }; # Authorize if (method=="REGISTER") { if (!www_authorize("64.81.40.173", "subscriber")) { www_challenge("64.81.40.173", "0"); log(1, "BAD REGISTER\n"); break; }; save("location"); break; }; exec_msg('`/root/bin/logcdr.pl`'); loose_route(); if (method=="INVITE") { record_route(); if (!exec_msg('`/root/bin/test.pl`')) { t_reply("404", "Low Funds"); break; }; }; if (uri =~"^sip:[0-1]") { if (uri =~"^sip:1666") { rewritehostport("216.91.9.42:5060"); if (!t_relay()) { sl_reply_error(); }; break; }; if (uri =~"^sip:1") { rewritehostport("128.121.29.99:5060"); if (!t_relay()) { sl_reply_error(); }; break; }; if (uri =~"^sip:011") { rewritehostport("128.121.29.99:5060"); if (!t_relay()) { sl_reply_error(); }; break; }; if (uri =~"^sip:00") { strip(2); prefix("011"); rewritehostport("128.121.29.99:5060"); if (!t_relay()) { sl_reply_error(); }; break; }; } else { if (!lookup("location")) { sl_send_reply("404", "User Not Found"); log("SER: Dest User Not in location table.\n"); break; }; if (!t_relay()) { sl_reply_error(); }; break; }; }

Could someone please elaborate on this a bit more? I have looked through the last two months of the serusers archive and can't find any reference to it.

[Serusers] Server error
by Urvish Khandwalla 26 Nov '03

26 Nov '03

i have a 6 line SIP phone. Its IP address is 192.168.1.159. Im placing a call to 5555 ( another line on the same phone). I have set the proxy for both the lines to my SERs IP address (192.168.1.240).I havent enabled register with proxy on the phone but i tried that before and that gave me the same server error as the one mentioned below. These are the packets that i have captured while making the call. Now the problem is that I am unable to understand the kind of internal error it is giving. 18 6.670873 192.168.1.159 192.168.1.240 SIP/SDP Request: INVITE sip:5555@192.168.1.240, with session description 19 6.671179 192.168.1.240 192.168.1.159 SIP Status: 100 trying -- your call is important to us 20 6.732622 192.168.1.240 192.168.1.159 SIP Status: 500 I'm terribly sorry, server error occured (2/TM) 21 6.801520 192.168.1.159 192.168.1.240 SIP Request: ACK sip:5555@192.168.1.240 Also the SIP message header of Packet 20 , as shown below, talks about warning 392.

[Serusers] 0.8.12 usrloc + mysql crashing !
by Tristan Colgate 26 Nov '03

26 Nov '03

Hi, I've been running a CVS version of ser recently with no problems, however I wanted to move back to using a release version so have downloaded 0.8.12, things seemed to be going OK, but it seems that SER crashes when my REGISTER stuff attempts to do a save("location"), I am doing a check_to before that it that works fine and queries the mysql backend no problems, I am using db_mode = 1 if that makes a difference, I tried using mode 2, which seemed to work but then crashed later (presumably when trying to write to the db). Nothing is ending up i the database and I am not seeing any INSERTs arriving at the database server. The error output I see after the check_to seems to work is.... 11(3419) check_username(): From/To user '8540' and auth user match 11(3419) parse_headers: flags=-1 19(3427) BUG: tcp_main_loop: dead child 11 0(3408) child process 3419 exited by a signal 11 0(3408) core was not generated 0(3408) INFO: terminating due to SIGCHLD 1(3409) INFO: signal 15 received 1(3409) Memory status (pkg): ..... -- Tristan Colgate Inux Technologies E-Mail: tristan(a)inuxtech.co.uk Mobile: 07900 690 912

[Serusers] Does SER support virtual IP interfaces?
by Michael C. Cambria 26 Nov '03

26 Nov '03

Hi, I've installed ser-0.8.11 on FreeBSD via ports. Things run fine on a private LAN. I have setup a pp2p tunnel, which shows up as ng1 in FreeBSD's ifconfig. This allows Windows users at the remote end of the tunnel to see the FreeBSD box just fine. The pp2p tunnel runs over a NAT'ed, public IP address to another box which does the same thing. However, NAT isn't (or shouldn't be) in the loop as the pp2p tunnel hides all this. The public internet looks like one p2p link. I've verified the above via tcpdump using many different applicationss. Private addresses are used on both LAN's. Any box can see any box just fine. On one FreeBSD machine, I am also running SER. It doesn't seem to respond to the register SIP message. SER is listening ONLY to the ip address that corresponds to its end of the pp2p tunnel. Before I dig into what I might be doing wrong, I'd like to know if the above is even supported. Thanks, MikeC

[Serusers] CISCO returns "481 Call Leg/Transaction Does Not Exist"
by - zaki - 26 Nov '03

26 Nov '03

Hi, I'm using ser-0.8.12 for SIP proxy and CISCO2651XM(12.2(11)T8) as media gateway for PSTN. When any subscriber call to PSTN via CISCO media gateway, CISCO returns "SIP/2.0 183 Session Progress", and if caller hang up before called party in PSTN pick up a call, CISCO send a packet of "SIP/2.0 481 Call Leg/Transaction Does Not Exist" and call between CISCO and PSTN called party is not hung up. (Called party phone continue ringing) (I consider that transaction before caller party pick up is not added CISCO's transaction table.) Could anyone please let me know how to terminate a call between CISCO media gateway and called party in PSTN?
