[Users] Issues with calls using openser.
by Shane Burrell 04 Jan '07

04 Jan '07

I recently installed the latest version of openser and this time used mediaproxy rather than rtpproxy. Everything seems to work but if a sip device is called the phone rings and is instantally disconnected and the far end is left off-hook. This worked before but I did modify my script to work with mediaproxy. Below is the wireshark decode of the sip messagining. Any help or suggestions on where to look would be great. Calls from the sip device works flawlessly. I am using a MaxTNT as the gateway. |Time | 152.93.36.91 | siprt1.me.net| 152.93.37.83 | |22.031 | INVITE SDP ( telephone-event) | |SIP From: sip:8385021101@152.53.16.91:5060 To:sip: 8385024200@ siprt1.me.net:5060 | |(5060) ------------------> (5060) | | |22.031 | 100 Giving a try | |SIP Status | |(5060) <------------------ (5060) | | |22.031 | | INVITE SDP ( telephone-event) |SIP Request | | |(5060) ------------------> (5060) | |22.040 | | 100 Trying| |SIP Status | | |(5060) <------------------ (5060) | |22.042 | | 180 Ringing |SIP Status | | |(5060) <------------------ (5060) | |22.042 | 180 Ringing | |SIP Status | |(5060) <------------------ (5060) | | |25.244 | | 200 OK SDP ( telephone-event) |SIP Status | | |(5060) <------------------ (5060) | |25.245 | 200 OK SDP ( telephone-event) | |SIP Status | |(5060) <------------------ (5060) | | |25.269 | ACK | | |SIP Request | |(5060) ------------------> (5060) | | |25.269 | | ACK | |SIP Request | | |(5060) ------------------> (5060) | |25.269 | INVITE SDP ( telephone-event) | |SIP From: sip: 8385021101@152.93.36.91:5060 To:sip: 8385024200@ siprt1.me.net:5060 | |(5060) ------------------> (5060) | | |25.270 | 407 Proxy Authentication Required | |SIP Status | |(5060) <------------------ (5060) | | |25.291 | ACK | | |SIP Request | |(5060) ------------------> (5060) | | |25.291 | BYE | | |SIP Request | |(5060) ------------------> (5060) | | |25.293 | | BYE | |SIP Request | | |(5060) ------------------> (5060) | |25.326 | | 200 OK | |SIP Status | | |(5060) <------------------ (5060) | |25.327 | 200 OK | | |SIP Status | |(5060) <------------------ (5060) | | Shane

[Users] How relay/retransmit subscribe, notify or publish messages...
by Marvin Ottley 03 Jan '07

03 Jan '07

Good day all, Currently I'm working on an interface/design where I have openser relaying messages to asterisk servers. The stumbling block I've run into is having openser relay SUBSCRIBE, NOTIFY or PUBLISH messages to Asterisk. So far, I've tried using openser's forward() and t_relay() functions without success; By the way, these work just fine with INVITE and REGISGER messages. Any pointers would be greatly appreciated Thanks, Marvin Ottley Email: marvino(a)nbsvoice.com <mailto:marvino@nbsvoice.com> This email may contain confidential and/or privileged information, and is intended solely for the addressee identified above.

[Users] several presence question
by Klaus Darilion 03 Jan '07

03 Jan '07

Hi! I read the docs of the presence module and have some question. Maybe someone can enlighten me ;-) 1. If I understand correctly, the pua module acts as a "UAC". Thus, it can be used to send PUBLISH or SUBSCRIBE. I wonder what is the usecase for sending SUBSCRIBE? Usually, a client which sends a SUBSCRIBE receives subsequent NOTIFY messages. How can these NOTIFY messages be handled? 2. If an external application sends PUBLISH via the uac_mi interface, how can be distinguished between a "new" PUBLISH or an "update" PUBLISH? For example if the MI interface returns the E-Tag from the 200 Ok response this could be used in the next request to group identify PUBLISH reqeusts which belong together. 3. There is a bug in the pua module docs: the db_url(str) parameter is described twice. 4. The following module documentations lack of default values for the module parameters: pua, pua_usrloc, presence (maybe some example show the default value, but IMO the default value should be explicitely stated) 5. How can I update the presence status from a third party application? Is it possible to write directly into the tables of the presence modules? Or can I fake an update using the pua_mi to loop a PUBLISH to itself for handling it afterwards with handle_publish()? May this cause problems because it interferes the subsequent PUBLISH request from the client (etag)? regards Klaus

RE: [Users] SER as proxy in front of Asterisk

Hi, In fact, now, every phone does not response. The options didn't go thought the FW, so, the phone cannot answer. I don't understand why the traffic don't go thought it !! I have test this configuration with two firewall: a sonicwall and a soho.

As I can see from the diagram, the phone does not reply to OPTIONS request, and I guess, the nat/firewall needs outward traffic to keep the pinhole open. Check why thomson ignores the options requests.

Hi, I have made more tries and now, all my phones don't work ... The firewall opens a connection to REGISTER phone but after a while the OPTION message from the Asterisk will be DROP by the FW ... You can find a diagram of the exchange here: http://deillon.eu/tmp/exchange_sip.png A list of all exchange: http://deillon.eu/tmp/ip_sip.txt And all sip message: http://deillon.eu/tmp/message.txt Thanks a lot for your help, Thomas ________________________________ De : users-bounces(a)openser.org [mailto:users-bounces@openser.org] De la part de Thomas Deillon Envoyé : mardi, 2. janvier 2007 11:44 À : users(a)openser.org Objet : [Users] SER as proxy in front of Asterisk Hi all, I wish you first a happy new year !! One again, I ask you some help. Thanks a lot for your patience and your answers that really helped me. So, I want to put a SER in front of one Asterisk for the moment (more after). All Servers have public IP address and so, I don't care about the RTP/SDP messages. All phones are behind NAT somewhere in Switerland :) I have the configuration below in openser: modparam("dispatcher", "list_file", "/etc/openser/dispatcher.list") #modparam("dispatcher", "force_dst", 1) modparam("dispatcher", "flags", 2) modparam("usrloc", "db_mode", 0) #modparam("rr", "enable_full_lr", 1) route{ xlog("L_ALERT", "[$rm] from [$fu] to [$tu]\n"); if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; # if (search("User-Agent:.*Thomson.*")) { # }; if ((src_ip==212.xxx.xxx.152) || (src_ip==212.xxx.xxx.153)) { if(method=="OPTIONS") { }; avp_pushto("$ru","$tu"); forward(); }else { fix_nated_contact(); force_rport(); if(method=="REGISTER"){ ds_select_dst("4", "0"); t_relay(); } else { ds_select_dst("0", "4"); forward(); } } } And in my dispatcher.list I have: 0 sip:212.xxx.xxx.153:5060 4 sip:212.xxx.xxx.153:5060 With this configuration, a snom phone, a X-lite phone and a Cisco phone seams to work .... But with the Thomson ST2030, it doesn't work. In fact, the Thomson REGISTER on asterisk, the Asterisk send a OPTION message to the FW IP adress and the right port where the thomson is and then, after a while, the FW close the connection. The thomson phone is so "UNREACHABLE" on asterisk status and nobody can call it. I'm not sure that my configuration is ok in ser but I think that is a problem with the Thomson2030. Do you had the same kind of problem or do you understand the problem here ? Thanks for your help, Thomas Deillon

[Users] Problem registering the UA with openSER(tls enabled)
by Ncheeku Baranov 03 Jan '07

03 Jan '07

Hi, I am trying to make my non-TLS/TLS UA register with my TLS enabled openSER. Currently I am just working on my local machine with the client UAs on the same subnet,(so there is only one domain, but its not named). Below is my configuration file: disable_tls = 0 listen = tls:10.30.100.41:5061 tls_verify_server = 1 tls_verify_client = 0 tls_require_client_certificate = 0 tls_method = TLSv1 tls_certificate = "/usr/local/etc/openser/tls/user/user- cert.pem" tls_private_key = "/usr/local/etc/openser/tls/user/user- privkey.pem" tls_ca_list = "usr/local/etc/openser/tls/user/user-calist.pem" However, with the above configuration the client UAs couldnot register and I got 408 Request Time out Message. Is there any field that is missing to make this simple scenario work? What should be the values of "tls_client_domain" and "tls_server_domain" fields in this case? I noticed that when I start the openSER without TLS support using "openserctl start" and do "ps -e" after that, there are more openSER processes running than if I start openSER with TLS support in which case I see very few of these processes running. Your help is much appreciated.... Best regards, NCheeku

[Users] 487 Transaction Terminated
by KOK FOON YEW 03 Jan '07

03 Jan '07

This is pertaining to call cancel operation where the calling UA sends a CANCEL request via openser to the called UA. After the UA sends ACK in response to 487 Transaction Terminated response, 487 responses are re-transmitted by openser to the UA as if the SIP proxy didn't regcognise the ACK request. I have tested with other UA and compare the differences between the ACK sent by UA that worked and UA which has this problem. The difference is that the ACK sent by the UA having this problem has a route header added. Foon-Yew Kok [This e-mail is confidential and may be priviledged.

[Users] Accounting using dialog and sst module
by Asterisk Expert 03 Jan '07

03 Jan '07

Hello, I am currently trying to do accurate billing with openser. I found that dialog and sst modules can be used to determine failed transactions. i.e. If UA crashed and no BYE received at all. I tried to configure dialog and sst modules as specified in the documentation. But active dialogs keep incrementing even after hangup. It would be nice if someone can post a good example. I am using cvs head of openser. Snippet of config is as below: ###################### DIALOG ###################### modparam("dialog", "dlg_flag", 13) modparam("dialog", "timeout_avp", "$avp(i:10)") modparam("dialog", "use_tight_match", 1) modparam("dialog", "enable_stats", 1) ###################### SST ###################### modparam("sst", "enable_stats", 1) modparam("sst", "timeout_avp", "$avp(i:10)") modparam("sst", "sst_flag", 14) route { ........ ........ if(method=="INVITE") { setflag(13); # set the dialog flag setflag(14); # Set the sst flag avp_write("15","$avp(i:10)"); }; if (method=="INVITE") { record_route_preset("192.168.1.2:5060;nat=yes;did=1"); }; ......... ......... } -- Regards Asterisk Expert
