[OpenSER-Users] OpenSER with PostgreSQL
by Cliff Flood 04 Sep '07

04 Sep '07

Hi, I have an Ubuntu 6.06 install with PostgreSQL 8.1 and OpenSER 1.2.2 which I am testing at the moment. I have tested OpenSER with MySQL and it worked fine but when when I want to switch to PostgreSQL I'm having some difficulty. I have used the postgressqldb.sh script to initialise the database and it has completed without error. When I start OpenSER I get the following lines in my PostgreSQL logs: LOG: connection received: host=127.0.0.1 port=37610 LOG: connection authorized: user=openser database=openser LOG: SSL SYSCALL error: EOF detected LOG: could not receive data from client: Connection reset by peer LOG: unexpected EOF on client connection I have looked at OpenSER's logs with debugging turned on but I don't see anything that looks like an error but I would be happy to provide them. `openserctl moni` returns: ERROR: Error opening OpenSER's FIFO /tmp/openser_fifo ERROR: Make sure you have the line 'modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo")' in your config ERROR: and also have loaded the mi_fifo module. My openser.cfg looks like this: debug=9 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) children=4 listen=192.168.20.151 dns=no rev_dns=no port=5060 mpath="/usr/local/lib/openser/modules/" loadmodule "mysql.so" loadmodule "postgres.so" loadmodule "sl.so" loadmodule "tm.so" loadmodule "rr.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "mi_fifo.so" loadmodule "auth.so" loadmodule "auth_db.so" modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo") modparam("usrloc", "db_mode", 2) modparam("usrloc", "db_url", "postgres://openser:openserrw@localhost/openser") modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "db_url", "postgres://openser:openserrw@localhost/openser") modparam("auth_db", "password_column", "password") modparam("rr", "enable_full_lr", 1) 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"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; # 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 if (!method=="REGISTER") record_route(); # subsequent messages withing a dialog should take the # path determined by record-routing if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); }; if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); # if you have some interdomain connections via TLS #if(uri=~"@tls_domain1.net") { # t_relay("tls:domain1.net"); # exit; #} else if(uri=~"@tls_domain2.net") { # t_relay("tls:domain2.net"); # exit; #} route(1); }; # 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 (!www_authorize("host.doman.tld", "subscriber")) { # www_challenge("host.domain.tld", "0"); # exit; # }; save("location"); exit; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); exit; }; append_hf("P-hint: usrloc applied\r\n"); }; route(1); } route[1] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; exit; } Any and all help appreciated. -- Cliff Flood Systems Administrator Jazinga Inc.

[OpenSER-Users] t_relay after failure_route -- problem
by Zahid Mehmood 03 Sep '07

03 Sep '07

Hi All, I am trying to implement serial forking and am using the example on voice-systems website as a guide. The problem I am experiencing is as follows. Failure route rewrite ruri with the next uri to try and calls route[17] route 17 performs a lookup("location"), finds the usrloc information and rewrites ruri, however, when t_relay is called it uses the original ruri (one before the lookup) to do t_relay. Another issue I'm experiencing is that when processing call after failure route, ruri_user_avp. Once i rewrite the uri in failure route, I have to use the following to manually write a value for ruri_user_avp. Can someone explain why this is happening? Thanks in advance for your help!! -- Zahid ] Some relevant config and debug info: modparam("lcr", "gw_uri_avp", "1400") modparam("lcr", "ruri_user_avp", "1402") route[18] { # used to process pstn/ off system calls ...... if (!is_avp_set("$avp(i:1402)")) { xlog("L_INFO","$ci: route[22] ** setting ruri_user_avp **\n");

Re: [Serusers] Can't make a single call. Help me please.
by Harmeet Singh 03 Sep '07

It's strange, but I do see the SIP INVITE messages being sent in the ethereal log. Why they don't reach to the server? SER is connected directly to the internet, without any NAT. On the other hand, REGISTER messages do get to SER and the client recieves the 200 OK and all intermediate replies as well. I have attached the clientside ethereal log for you to see. I am lost.

[OpenSER-Users] checking radius return attributes
by danish.samad＠vocalseeds.com 01 Sep '07

01 Sep '07

Hi, I have configured openser-1.2 with a (commercial) third party radius server and it is working great. Now I have a requirement where I need to check a radius return attribute in case an access reject is received in response to an authorization request. Is there some way I can do this in the openser script. Basically I want to send a 402 payment required message to a sip client in case the call is rejected due low balance. In such cases radius returns a status response code with access reject. Thanks, Danish

[Serusers] Can't make a single call. Help me please.
by Harmeet Singh 31 Aug '07

31 Aug '07

Hi allAfter spending whole week reading and googling I am writing here. Hope someone from here can help me.Here is my setup -I have a Fedora 7 desktop with SER, mysql, and rtpproxy running. This is connected directly to the cable modem. There is not NAT in between. Firewall and SELinux are disabled.I have X-Lite client on my Laptop connected to a Wi-Fi router on a different IP. This router has NAT but the firewall is disabled in the router.On the far end, my sister has X-Lite on her desktop which is also behind NAT.Both X-Lite clients can REGISTER and the SIP server sends 200 OK. But can't make calls.When all clients and SER are on the same network with local IP addresses, I can make calls between the X-Lite clients and SJPhone on different computers. No problem. And Grandstream phones also work in the local setup.Any help is appreciated.HS

[OpenSER-Users] avp_substr, re-index's lists?
by Brandon Armstead 31 Aug '07

31 Aug '07

Hello, Say I have something like the following: $avp(a[0]) = "27*" $avp(a[1]) = "22*" Then I run avp_substr like the following: avp_subst("$avp(a)/g", "/\*/[0-9]/g"); As you would expect it to simply strip * from the avp list values, instead it decides to rewrite the index in numerical order, so the avp's would now look like: [ BAD RESULTS ] $avp(a[0]) = "22"; $avp(a[1]) = "27"; however the [ EXPECTED RESULTS ] $avp(a[0]) = "27"; $avp(a[1]) = "22"; Could someone please elaborate on why OpenSER would re-numerate the list index on a simple avp_substr, also any ideas on how I can get around this and stop this from happening? Thanks!

[OpenSER-Users] Openser for voip+presence+IM
by Alejandro Cabrera Obed 31 Aug '07

31 Aug '07

Dear all, I'm using Debian Etch + Asterisk 1.2.13 as our VoIP server. I have several clients talking to each other but now I need to implement presence+instant messaging also. People told me that Asterisk does not support presence+IM, so I have to use another SIP server like OpenSER. I've never used OpenSER so I need to know the following: Is Openser enough to get just several X-Lite (softphones) clients using voip+presence+IM, without connecting to the PSTN ??? Or do I need the integration with Asterisk to get what I need ??? Really thanks Alejandro
