Registering "upstream" with the uac module, but with authentication

by Steve Davies

Hi, I'm making slow but steady progress with my Kamailio project. My next task: I need to "relay" a registration to an upstream service. IE when one or more devices registers against my local registration service, I need to initiate a corresponding registration upstream. If all my local devices unregister, all all the registrations lapse, I want to drop the upstream registration. There is an example a bit like this in the Asterisk integration example. However in that case the Asterisk doesn't challenge for authentication. My upstream does. I can't find anything in the uac module docs about authenticating. Is there any way to handle this. One thing I did try was to create "uacreg" as a view, and use that as the source of upstream registrations: CREATE VIEW `uacreg` AS select distinct `s`.`id` AS `id`,`l`.`username` AS `l_uuid`,`l`.`username` AS `l_username`,`s`.`domain` AS `l_domain`,`l`.`username` AS `r_username`,`s`.`domain` AS `r_domain`,`s`.`domain` AS `realm`,`l`.`username` AS `auth_username`,`s`.`password` AS `auth_password`,concat('sip:',`s`.`domain`,':5060') AS `auth_proxy`,timestampdiff(SECOND,now(),`l`.`expires`) AS `expires` from (`location` `l` join `subscriber` `s`) where (`l`.`username` = `s`.`username`) This kinda worked - but didn't quite track the registration status. Do you think this idea has promise? Maybe something similar that works using triggers rather than a straight view might work better? Thanks, Steve -- Steve Davies: Technical Director, Connection Telecom (Pty) Ltd

Calling users on another kamailio server

by Brian Wallen

I currently have two independent kamailio servers. I'd like to set them up in a way that user1 on server1 can make a call to user2 on server2. After searching I've come up with two ways that this might be able to be done. Can someone please sanity check these or point me in the right direction? 1. Have one registrar server and convert the other server to a proxy 2. Keep them both as registrars and somehow make them each aware of the users on the other server I like 2 better because if one server went down users on the other server would still be up. The only thing is I don't know how to set the servers up to communicate with each other.

kamailio presence and XCAP related issue

by Rupayan Dutta

Dear All, .May be I couldn't express my doubt properly ijn my earlier mails.Actually we were testing OfficeSIP server with SipML5 client for multiparty videoconferencing with presence enabled for showing buddy list and it is working properly.Now as we moved to kamailio with same client and configuring kamailio with Websocket and presence support, I have noticed that the presentity and xcap tables are not populated but location,watchers and active watchers tables are showing correct entries after a user logs in using sip over websocket from SIPML5. I have followed the steps as described in " http://kb.asipto.com/kamailio:presence:k31-made-simple". As Sipml5 sends PUBLISH/NOTIFY request in pidf format is this is the possible cause?As I am a person from java based web application technology it is really hard for me to detect the root cause.Please give me some idea regarding this issue.

Asterisk and Kamailio Integration CAPACITY ISSUE

by Hassan Wajahat

Hi, I followed your tutorial and the setup is running seamlessly. But the question is that I read somewhere that asterisk can make up to 300 to 400 concurrent sip calls. Higher than that will cause problems. Will that issue appear here as well since you are using asterisk in the sip calling process?? Regards, Hassan Wajahat

Kamailio realtime fails to forward register with Asterisk.

by imperium broadcast

Hi all I have been trying to figure out where Im going wrong with following this guide: http://kb.asipto.com/asterisk:realtime:kamailio-3.3.x-asterisk-10.7.0-astdb The only thing that is different is I am using Asterisk 1.8.22.0 Kamailio works fine and I am able to register a phone to it but the forward register fails to register with Asterisk. Its like Asterisk doesn't see the request even running sip debug on the Asterisk Console it doesn't show the register attempts. I have to use ngrep to see any thing. Realtime works fine when I register the phone on Asterisk. Although I can get round the register using AGI I get the same issue when passing a call to asterisk, Asterisk doesn't see the invite. Am I missing something so obvious :-/ This is what I have in sip.conf "IP change to protect the innocent!"

issues with dispatcher rerouting to next server when getting a 500 from freeswitch

by Joseph Watson

Hello Everyone, I am really having an issue getting kamailio to try another dispatch route when I get a 500 back from one of my freeswitch servers. Currently I have a list of freeswitch servers located in my dispatch.list file. If one of then is to busy it will respond with a 500 Maximum Call in Progress.

json module / quotes in result

by Florian Lohoff

Hi, is it correct that the json_get_field returns the quotes from the json document? Example: { "foo": "bar" } json_get_field("$var(json)", "foo", "$var(result)"); result will contain "bar" with quotes ... I was a little astonished to see that. Flo -- Florian Lohoff f(a)zz.de

Pseudo-variables and branches

by Steve Davies

Hi - Can someone help me understand how pseudo-variables interact with branches? I've written this logic in my failure route to do a reroute of calls if the primary destination fails: if ( is_method("INVITE") && !t_check_status("407") && ($rd != "127.0.0.1") ) { # Maybe should also check its not just a Busy or similar xlog("L_NOTICE","SLD: INVITE failed $rm ($mt / $rs $rr): $ci::$ft; try via asterisk instead\n"); append_branch("sip:$rU@127.0.0.1:5070"); send_reply("181", "Rerouting call via local failover"); $avp(senttoast) = 1; if (!t_relay()) { sl_reply_error(); # or reply_error ? } I'm trying to check if the call was already rerouted - by looking at $rd. But in fact I find that $rd keeps the domain from the ORIGINAL invite even if the call that just failed was the one to 127.0.0.1:5070 . So I'm obviously missing something about how pseudo-variables interact with the branching etc. Thanks, Steve -- Steve Davies: Technical Director, Connection Telecom (Pty) Ltd Email is preferred, but: Phone: 0878200200
