rtpproxy_manage fails to rewrite SDP
by Igor Potjevlesch 29 Oct '14

29 Oct '14

Hello, I'm working with rtpproxy module for managing calls to a particular route. The thing is that for some calls, the "Connection information" is not rewritten properly whereas another calls, less than 1 second before or after, are properly rewritten. When "cr_route" defines that the call must be route to this carrier, I go to a route in order to make some change: - Keep only PCMA, PCMU, G729a and telephone-event - Depends on the R-URI: o If the uri contains … [View More]

content-length mismatch for kamailio 4.2.x
by andrew 29 Oct '14

29 Oct '14

hi all, kamailio 4.2.x has been released, And I used two endpoint to test kamailio server. I install kamailio 4.2.x on centos 6.5 via 'yum'. One endpoint failed to call another, I captured packets via wireshark, and found that invite method is recognized as error sip signal because of content-length' mismatch. I examined the invite packets, and calculated content-length in invite signal. There is no mistake for the value of content-length. I guess it may be a bug in kamailio 4.2.x. But … [View More]

Setting up web sockets and ephemeral auth
by Nolan Darilek 27 Oct '14

27 Oct '14

Having a hard time piecing together lots of pieces out of context. Here's what I want: 1. User logs in to my web app via its own authentication mechanisms. 2. Via an authenticated REST endpoint, my web app connects to the ephemeral auth service and returns a temporary username/password to the client. 3. The client connects to a web socket SIP interface, authenticating with the username/password it was given. 4. I'd also like to support authentication via standard SIP client using the user's … [View More]default username/password, but that's a bit down the road still. Here is my kamailio-local.cfg. I'm using the web socket example copied from the docs, with a little cleanup and a few optional checks removed for now. loadmodule "db_mongodb.so" #!define DBURL "mongodb://mongo/perceptron" #!define WITH_AUTH #!define WITH_NAT loadmodule "xhttp.so" #modparam("xhttp", "url_match", "^/sip/") tcp_accept_no_cl=yes loadmodule "msrp.so" # Only required if using MSRP over WebSockets loadmodule "websocket.so" loadmodule "auth_ephemeral.so" modparam("auth_ephemeral", "secret", "Kamailio rulez!!11") event_route[xhttp:request] { set_reply_close(); set_reply_no_connect(); # xlog("L_DBG", "HTTP Request Received\n"); if ($hdr(Upgrade) =~ "websocket" && $hdr(Connection) =~ "Upgrade" && $rm=~ "GET" ) { # Validate Host - make sure the client is using the correct # alias for WebSockets if ($hdr(Host) == $null || !is_myself("sip:" + $hdr(Host))) { # xlog("L_WARN", "Bad host $hdr(Host)\n"); xhttp_reply("403", "Forbidden", "", ""); exit; } if (ws_handle_handshake()) { exit; } } xhttp_reply("404", "Not found", "", ""); } When I attempt to validate this, I get: 0(1) ERROR: <core> [pvapi.c:790]: pv_parse_spec2(): error searching pvar "hdr" 0(1) ERROR: <core> [pvapi.c:994]: pv_parse_spec2(): wrong char [U/85] in [$hdr( Upgrade)] at [5 (5)] 0(1) : <core> [cfg.y:3436]: yyerror_at(): parse error in config file /usr/local /etc/kamailio/kamailio-local.cfg, line 28, column 7-19: Can't get from cache: $h dr(Upgrade) ERROR: bad config file (1 errors) I don't know what that means. I've copied the config directly from the website. I tried quoting "Upgrade" and such in the $hdr lines, but that gives me: 0(1) ERROR: <core> [pvapi.c:790]: pv_parse_spec2(): error searching pvar "hdr" 0(1) ERROR: <core> [pvapi.c:994]: pv_parse_spec2(): wrong char ["/34] in [$hdr( "Upgrade")] at [5 (5)] 0(1) : <core> [cfg.y:3436]: yyerror_at(): parse error in config file /usr/local /etc/kamailio/kamailio-local.cfg, line 28, column 7-21: Can't get from cache: $h dr("Upgrade") ERROR: bad config file (1 errors) What am I missing here? I also had to comment out the xlog lines because those gave me errors. Do I need another module loaded to use xlog? Finally, does anyone have a working, complete example of SIP over web sockets with ephemeral auth integrated? I'm not sure if I should be checking the ephemeral auth credentials in the web sockets code, the SIP routes or somewhere else. I'm also not sure how I should set up authentication such that users can log in with both their standard credentials or those retrieved via the ephemeral auth module. Thanks. [View Less]

Integrating Kamailio with existing IMS
by Muhammad Shahzad 27 Oct '14

Hi, I am trying add WebRTC support to existing IMS using kamailio. The idea is to let kamailio handle all webrtc calls alone with diameter backend to IMS for AAA. So, i thought of using auth_diameter and aac module for authentication and accounting. However auth_diameter docs say that the module is obsolete and will work no more. Also i am not sure about how to use diameter support in aac module. So, is there any any tutorial or how-to for this? I am aware of ims_* modules but i think they … [View More]

best way to cope with peaks in traffic
by davy van de moere 27 Oct '14

27 Oct '14

Gents, assuming we don't use async methods (I know, it's against fashion), eventually you'll end up in having some bottlenecks in your config... Now thanks to a lot of children you can easily work around this, a maximum of 32 children gives you already quite something, and if you use the dispatcher, you can ramp that up to quite some capacity. ;) Now, there are moments where still limits are passed, so what would be the best way to keep your system healthy?

rtpengine not working with append_branch
by Yuriy Gorlichenko 27 Oct '14

27 Oct '14

Hello all. I use rtpengine and rtpproxy-ng module at kamailio for proxying RTP and modifying SDP between endpoints. I use two types of clients - such as WSS based and UDP based clients. I have a trouble with append_branch and rtpengine handling for this packets. I try to implement this logic of my script Logic of my script: --checking location table for rows with needed account --get info from contact at loop for every step --check technology (sip or ws) --append_branch with existing … [View More]destination for this account --rewrite packet with rtpengine to needed technology after loop forward packets via t_relay At listing bellow rtpproxy_manage have no flag "b" that implement needed functionality. It not included at the script because I tried include it but rtpengine says that ca nnot handle this request. As i understand this flag worked with rtpproxy and rtpproxy-ng apps only. Not with rtpengine. At my test I have 2 endpoints with WS and UDP phones (at fist step ir WS and 2 step it UDP). All calls going form asterisk via UDP. When I do these steps (at my script) I see packet at TCP dump and saw that sended only one packet to UDP but body of packet is WS. Then I saw log of kamailio. I see that at second step packet changed body to WS body (so strange because other steps before and after goes for UDP (as at logic of script)) If I set "b" flag I can call only UDP endpoint, but at log I see as I say that rtpengine can not do thomething with SIP packets and send with t_relay uncghanged UDP packet only. sql_query("ca", "select contact from location where username='$tU'", "ra"); xlog("rows: $dbr(ra=>rows) cols: $dbr(ra=>cols)\n"); if($dbr(ra=>rows)>0){ $var(i)=0; while($var(i)<$dbr(ra=>rows)){ xlog("L_INFO","SQL query return contact {$dbr(ra=>[$var(i),0])} for {$tU} at step {$var(i)}\n"); if ($dbr(ra=>[$var(i),0])=~"transport=ws"){ xlog("L_INFO", "This is a Websocket call to endpoint"); sql_pvquery("ca", "select received from location where contact='$dbr(ra=>[$var(i),0])'","$var(recieved)"); xlog("L_INFO","SQL query return recieved {$var(recieved)} for {$tU}\n"); $du=$var(recieved); xlog("L_INFO", "Request going FROM ASTERISK to WS.
