Hi, I have trouble with RTPPRoxy. I downloaded a everything.GettingStarted.tar.gz package from Onsip, hello-world.3.04.cfg and auth-mysql.3.05.cfg work but when i use nat-rtpproxy.3.04.cfg i get following errors. [root@localhost root]# /etc/init.d/rtpproxy start [root@localhost root]# /etc/init.d/ser restart Stopping ser: [FAILED] Starting ser: [ OK ] [root@localhost root]# serctl ul show Dumping all contacts may take long: are you sure you want to proceed? [Y|N] y Error opening ser's FIFO /tmp/ser_fifo Make sure you have line fifo=/tmp/ser_fifo in your config [root@localhost root]# By the way i don't see rtpproxy.sock under \var\run\ Questions: If i use rtpptoxy, how we start it? i do "/etc/init.d/rtpproxy start" then it doesn't show if that is started or not unless i run "ps -A" Can we put SER into DMZ and do port forwarding OR SER must have Puplic IP? If we can put SER on DMZ then what other ports need to be open beside 5060? # =============================================== debug=3 fork=yes log_stderror=no listen=x.x.x.x # put your server IP address here That is MY WAN IP. port=5060 children=4 dns=no rev_dns=no fifo="/tmp/ser_fifo" fifo_db_url="mysql://ser:heslo@localhost/ser" 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/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" loadmodule "/usr/local/lib/ser/modules/nathelper.so" loadmodule "/usr/local/lib/ser/modules/textops.so" loadmodule "/usr/local/lib/ser/modules/uri_db.so" loadmodule "/usr/local/lib/ser/modules/uri.so" modparam("auth_db|uri_db|usrloc", "db_url", "mysql://ser:heslo@localhost/ser ") modparam("auth_db", "calculate_ha1", 1) modparam("auth_db", "password_column", "password") modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "rtpproxy_sock", "unix:/var/run/rtpproxy.sock") modparam("usrloc", "db_mode", 2) modparam("registrar", "nat_flag", 6) modparam("rr", "enable_full_lr", 1) route { # ----------------------------------------------------------------- # Sanity Check Section # ----------------------------------------------------------------- if (!mf_process_maxfwd_header("10")) { sl_send_reply("483", "Too Many Hops"); break; }; if (msg:len > max_len) { sl_send_reply("513", "Message Overflow"); break; }; # ----------------------------------------------------------------- # Record Route Section # ----------------------------------------------------------------- if (method!="REGISTER") { record_route(); }; if (method=="BYE" || method=="CANCEL") { unforce_rtp_proxy(); } # ----------------------------------------------------------------- # Loose Route Section # ----------------------------------------------------------------- if (loose_route()) { if (has_totag() && (method=="INVITE" || method=="ACK")) { if (nat_uac_test("19")) { setflag(6); force_rport(); fix_nated_contact(); }; force_rtp_proxy("l"); }; route(1); break; }; # ----------------------------------------------------------------- # Call Type Processing Section # ----------------------------------------------------------------- if (uri!=myself) { route(1); break; }; if (uri==myself) { if (method=="CANCEL") { route(3); break; } else if (method=="INVITE") { route(3); break; } else if (method=="REGISTER") { route(2); break; }; lookup("aliases"); if (uri!=myself) { route(1); break; }; if (!lookup("location")) { sl_send_reply("404", "User Not Found"); break; }; }; route(1); } route[1] { # ----------------------------------------------------------------- # Default Message Handler # ----------------------------------------------------------------- t_on_reply("1"); if (!t_relay()) { if (method=="INVITE" && isflagset(6)) { unforce_rtp_proxy(); }; sl_reply_error(); }; } route[2] { # ----------------------------------------------------------------- # REGISTER Message Handler # ---------------------------------------------------------------- if (!search("^Contact:\ +\*") && nat_uac_test("19")) { setflag(6); fix_nated_register(); force_rport(); }; sl_send_reply("100", "Trying"); if (!www_authorize("","subscriber")) { www_challenge("","0"); break; }; if (!check_to()) { sl_send_reply("401", "Unauthorized"); break; }; consume_credentials(); if (!save("location")) { sl_reply_error(); }; } route[3] { # ----------------------------------------------------------------- # CANCEL and INVITE Message Handler # ----------------------------------------------------------------- if (nat_uac_test("19")) { setflag(6); } lookup("aliases"); if (uri!=myself) { route(1); break; }; if (!lookup("location")) { sl_send_reply("404", "User Not Found"); break; }; if (!proxy_authorize("","subscriber")) { proxy_challenge("","0"); break; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); break; }; consume_credentials(); if (isflagset(6)) { force_rport(); fix_nated_contact(); force_rtp_proxy(); }; t_on_reply("1"); if (!t_relay()) { if(isflagset(6)) { unforce_rtp_proxy(); } sl_reply_error(); }; } onreply_route[1] { if (isflagset(6) && status=~"(180)|(183)|2[0-9][0-9]") { if (!search("^Content-Length:\ +0")) { force_rtp_proxy(); }; }; if (nat_uac_test("1")) { fix_nated_contact(); }; } Thanks, Ali G.

[Serusers] Intrado 911 SER Module

by Darren Sessions

We are about to begin work on a 911 module specifically tailored to interop with Intrado's 911 service. I am curious if there is anyone out there that has either completed such a module, or might have some code already written to which we could collaborate on to get the finished product. Thanks, - Darren

[Serusers] append_branch And New totag Problem

by Corey S. McFadden

Guys, We're working with Tekelec to solve a problem we're experiencing with one of their SIP gateway cards. (We're working with a group that hadn't heard of SER before we talked to them, so this may or may not be correct.) What happens is this: 1. Call originates from SIP PSTN GW (Tekelec unit) 2. SER routes call to UA 3. UA doesn't answer 4. Failure route happens and call is diverted to Asterisk 5. Asterisk gets the call but the SIP PSTN GW doesn't ACK the OKs and hangs up. The scenario works with a variety of UA hardware, so I didn't think anything was wrong on our side, but they're saying that on the first phase of the call the totag has one ID and then when Asterisk gets involved there's a different totag ID. (This is confirmed w/packet captures.) When the GW card gets the second totag it doesn't match a transaction and it is ignored. So, my question is... can (and should) we rewrite the totags back to the original id? Can this be done w/textops? Is this a common problem? Does this make sense? Thanks for any help, -Corey ********************************************* This message has been scanned for viruses and dangerous content, and is believed to be clean.

[Serusers] BAD REQUEST from PSTN gateway

RE: [Users] how to modify record route header with advertised_address?

You can try to use record_route_preset, but be carefull!!!!! Samuel. Unclassified. >>> Gustavo García <ggb(a)tid.es> 09/13/05 05:20PM >>> Thank you for the information Bogdan. Acording to the "openser core cookbook" (http://openser.org/dokuwiki/doku.php?id=openser_core_cookbook): "represents the address advertised in Via header and other destination lumps (e.g RR header)" May be you might want to change it.
