[Serusers] Basic registration problem
by Gala, Dipen 01 Jul '04

01 Jul '04

UA ---------- SER --------- Asterisk (with registration, authentication, etc) -------- PSTN gateway (redirects) Now when I want my UA to register to asterisk I send I register request to SER, the SER then gives back a 302 message and give the ip address of the Asterisk indicates redirection. Then the UA should directly contact Asterisk and get it self register and SER should not be involved. But I am unable to register and asterisk gives me back 407 proxy authentication required. Though I can make call with right credentials I can not receive calls since the Asterisk does not know where the UA is and thus I cant have incoming calls. Also both my asterisk and Ser are in different domain. Can that be the problem or not??? Here is what I hv configured if (method="REGISTER"){ rewritehostport('ip address of asterisk:5060"); sl_send_reply("302" , "moved"); } Is there any error in this Pls folks help me out, I hv to get this working Thanks Dipen K Gala Fidelity Investments System Company - Telecom Phone: (617) 563-2729 Email: Dipen.Gala(a)FMR.com

[Serusers] request for comments
by Jev 01 Jul '04

01 Jul '04

I have made a diagram using Dia, of a ser footprint that I would like to put together. http://www.ecad.org/~jev/ser/SerFootprint.png The idea is that all user accounts, and locations (Down to ser/rtpproxy fronted) will be stored in the main Billing/User accounts back end. I want to have a farm of front end ser machines which will just proxy invites/registers/byes to the back end for authentication, authorization, and billing, and also proxy RTP by means of either Maxims rtpproxy or AG's mediaproxy. The front end SERs will be able to come and go, and our cisco router will manage the balancing (using things like 'sticky IP'). Depending on load we can just add more front end ser machines, and also possibly add more back end machines (using the t_replicate() mechanism) if need be. Currently I'm playing around in my test network getting this footprint to a functional state, I wanted to share the idea with community and see what you guys think of this setup? Weaknesses, [over|under] complicated? It is possible that some front end machines would be specific for a certain group of phones, based on latency (Different physical location). My main requirement is that I have a single billing/accounting mechanisism... Calls from one end point to the other will allways be mediated through a RTP proxy on one of the front end machines. What do you guys think?

[Serusers] Password challenge on invite

Hi, I am running a ser server right now with authentication from database, basically what happens now is that when the user connects to the ser server it will request a password for authentication only on initial login. what I want to do is also challenge for the password when the user wants to do an invite on a chat. any help would be greatly appreciated :-) thanks and best regards -Nathan here is my current ser config: ser.cfg # # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ # # simple quick-start config script # # ----------- global configuration parameters ------------------------ #debug=3 # debug level (cmd line: -dddddddddd) #fork=yes #log_stderror=no # (cmd line: -E) /* Uncomment these lines to enter debugging mode debug=7 fork=no log_stderror=yes */ debug=7 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" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/local/lib/ser/modules/mysql.so" 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/acc.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" #loadmodule "/usr/local/lib/ser/modules/auth_radius.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- # Uncomment this if you want to use SQL database # for persistent storage and comment the previous line modparam("usrloc", "db_mode", 0) # -- auth params -- # Uncomment if you are using auth module # modparam("auth_db", "calculate_ha1", 1) # # If you set "calculate_ha1" parameter to yes (which true in this config), # uncomment also the following parameter) # modparam("auth_db", "password_column", "password") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # -- acc params -- #modparam("acc", "log_level", 1) #modparam("acc", "radius_flag", 1) modparam("usrloc", "db_url", "sql://serro:47serro11@localhost/ser") # ------------------------- request routing logic ------------------- # 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; }; # 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") { # Uncomment this if you want to use digest authentication if (!proxy_authorize("", "subscriber")) { proxy_challenge("", "1"); break; }; 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 setflag(1); if (!t_relay()) { sl_reply_error(); }; }

[Serusers] slightly OT: client to work with SER
by Jeff Harrington 30 Jun '04

30 Jun '04

All, I'm trying to find a decent client to use with SER. The server is all set up and clients can make/receive calls, but there are a few options I would like to have. I need clients for at least Mac and Windows, preferably open source and relatively cheap. I've tried SJPhone, Xlite, Windows Messenger, and Mirial. None of them will pull down contacts that were set up on SERWEB when I register with my SER server. I wouldn't mind having a video option, but it's not required at this point. Anyone have any luck either with the clients I listed above, or use a client that would work? Thanks in advance, Jeff

[Serusers] SER + Asterisk Voicmail forward on failure
by Muhammad Nasim 30 Jun '04

30 Jun '04

Having searched the groups I have come up with the following in ser.cfg to forward calls from SER to Asterisk voicemail on timeout. The system should work as follows. E.g dial 8003. Ring phone at 8003 for 15 seconds then go to voicemail (at asterisk). Phenomena: 1. When the failure_route is exited though I can see some traffic hitting asterisk, the original phone at 8003 continues to ring. 2. If I press Deny on the phone at 8003 TWICE then the call goes to voicemail 3. If 8003 is on the offhook, call automatically goes to voicemail Points 2 and 3 are pretty much what I want. But in point 1, what am I doing wrong that doesn't cause the t_on_failure to stop ringing the destination phone. I include the relevant part of my ser.cfg below ............................ log("\nMARKER VOICEMAIL ATTEMPT STARTS HERE\n"); t_on_failure("1");#send to voicemail now log("\nMARKER VOICEMAIL ATTEMPT STOPS HERE\n"); ............................ ............................ failure_route[1] { log("\n MARKER IN FAILURE ROUTE START"); if(t_check_status("408")){ log("\nMARKER We have hit second status 408\n"); }; revert_uri(); rewritehostport("telth3.dyndns.org:5061"); append_branch(); log("\n MARKER IN FAILURE ROUTE AFTER APPEND BRANCH\n"); t_relay_to_udp("telth3.dyndns.org","5061"); log("\n MARKER IN FAILURE ROUTE END"); break; } ~ Muhammad Nasim TelAppliant Ltd Tel: 020 7740 3492 Int: +44 20 7740 3492 Main: 0845 004 4040 Fax: 0845 004 4041 www.telappliant.com TelAppliant is the UK's provider of IP telephony solutions for small and medium-sized businesses _____ The information in this message is confidential and may be legally privileged.

Andrei, Thanks for your help, we upgraded the RPM to 0.8.12 and the subst_uri works like a chrarm! -Mark -----Original Message----- From: Mark Wehberg [mailto:mark.wehberg@clearviewcatv.net] Sent: Monday, June 28, 2004 1:25 PM To: 'Andrei Pelinescu-Onciul' Cc: 'serusers(a)lists.iptel.org' Subject: RE: [Serusers] Replacing URI Andrei, I need to check if we are running the RPM, /root/ser-0.8.11-0.i386.rpm, or if we compiled the source code.

Which version of SER was this introduced in? It should be in ser 0.8.12. It was introduced before 0.8.12 was released. What's your modules/textops/textops.c version? If it's > 1.28 then it should be in. Andrei

[Serusers] dns configuration for enum
by Tirpák Miklós 30 Jun '04

30 Jun '04

Hello! Has anybody a dns (bind9) configuration with wildcards on Debian? I would like to migrate a nameserver from redhat 7.3 to debian, but I get the followin error: patrolsrv:~# host -t any 1.2.2.6.3.voip.hbone.hu 1.2.2.6.3.voip.hbone.hu does not exist at localhost (Authoritative answer) The NAPTR recods look like this: *.6.3.voip.hbone.hu IN NAPTR 10 10 "u" "e2u+sip" "!^(.*)$!sip:\\1@10.0.0.1!" . *.0.2.6.3.voip.hbone.hu IN NAPTR 10 10 "u" "e2u+sip" "!^(.*)$!sip:\\1@10.0.0.2!" . Some other queries result correct answers: patrolsrv:~# host -t any 1.1.1.6.3.voip.hbone.hu 1.1.1.6.3.voip.hbone.hu NAPTR 10 10 "u" "e2u+sip" "!^(.*)$!sip:\\1@10.0.0.1!" . patrolsrv:~# host -t any 1.0.2.6.3.voip.hbone.hu 1.0.2.6.3.voip.hbone.hu NAPTR 10 10 "u" "e2u+sip" "!^(.*)$!sip:\\1@10.0.0.2!" . The nameserver works good on rendhat. Is there a known bug in the bind9 on Debian? Or is something missing in the configuration? Thanks, Miklos Tirpak
