how to combine alias_db_lookup() with lookup()
by x-kamailio＠sidell.org 02 Mar '11

02 Mar '11

I'm trying to use the db_alias module as a way to define "generic" addresses that map to a set of actual phones. For example, I'd like the alias "home(a)foo.bar" to map to "kitchen(a)foo.bar" and "office(a)foo.bar", so that both phones ring when a call comes in to "home". I have set the append_branches param to 1: modparam("alias_db", "append_branches", 1) I also modified the dbaliases database table so that key "alias_idx" isn't unique, thereby allow me to add multiple rows for the same alias. The relevant script section is taken verbatim from 3.1 kamailio.cfg: # USER location service route[LOCATION] { #!ifdef WITH_ALIASDB # search in DB-based aliases alias_db_lookup("dbaliases"); #!endif if (!lookup("location")) { switch ($rc) { case -1: case -3: xlog( "L_WARN", "XXX $ru $fu\n"); t_newtran(); t_reply("404", "Not Found"); exit; case -2: sl_send_reply("405", "Method Not Allowed"); exit; } } # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } } When I place a call to an alias, the kamailio debug log shows that alias_db_lookup() is correctly setting the ruri to the first entry found in the table, and using append_branch() to add the others. But only the first matching phone gets an INVITE, not the others. I suspect that the lookup() call is blowing away the branches set up by alias_db_lookup() and replacing them with the single phone that matches the ruri for the first alias entry. Is there a way to get alias_db_lookup() and lookup() to play together, so that the first function can set up a list of branches, and the second function can resolve all of the branches to the actual device locations? -- Mark Sidell Partner Forte, Inc. 919-942-7068 fax 919-969-2844 www.forteinc.com

Radius authentication
by Pablo Ros 02 Mar '11

02 Mar '11

I am trying to authenticate through radius (info in LDAP database). I am using kamailio 3.1 First of all I would like to clear up an issue: As shown the way to do the authentication is done with: *Code:* if (! radius_www_authorize("uu.net")) { www_challenge("uu.net", "0"); return; } Ok, when I installed openser I did it with kamailio "flavour" so it was using the auth_radius module belonging to it. Does anyone know which would be the correct way to do the challenge to the user cause is was not working at all. The radius client does not even send it. I got stuck some time till I just decided to load the module from ser modules folder and then freeradius server started to get correctly my requests. Actually I can even see it authenticates them correctly. However Openser/Kamailio doesn't seem to see the same and it doesn't saves location. *Code:* route[AUTH] { #!ifdef WITH_AUTH # Primeramente comprobamos si pertenece a nuestro dominio; si no ya no hace falta comprobar credenciales. if (uri==myself) { if (is_method("REGISTER")) { xlog("L_NOTICE","KAM-INFO: r[AUTH] - REGISTER - User info: ($fu):($si)>\n"); if (!radius_www_authorize("i2cat.net")){ route(RADIUS); #www_challenge("i2cat.net","0"); exit; } } if ($au!=$tU) { sl_send_reply("403","Forbidden auth ID"); exit; } } else { #!ifdef WITH_IPAUTH if(allow_source_address()) { # source IP allowed return; } #!endif # authenticate if from local subscriber if (from_uri==myself) { if (!proxy_authorize("$fd", "subscriber")) { proxy_challenge("$fd", "0"); exit; } if (is_method("PUBLISH")) { if ($au!=$tU) { sl_send_reply("403","Forbidden auth ID"); exit; } } else { if ($au!=$fU) { sl_send_reply("403","Forbidden auth ID"); exit; } } consume_credentials(); # caller authenticated } else { # caller is not local subscriber, then check if it calls # a local destination, otherwise deny, not an open relay here if (!uri==myself) { sl_send_reply("403","Not relaying"); exit; } } } #!endif return; } Before doing the challenge then it just goes throught: *Code:* route[RADIUS] { sl_send_reply("100", "Trying"); append_to_reply("Expires: 600\r\n"); append_to_reply("Min-Expires: 240\r\n"); xlog("L_NOTICE","KAM-INFO: RADIUS AUTHENTICATION - AUTHORIZING USER $fU - <$fu>:<$si>\n"); xlog("L_NOTICE","KAM-INFO: CHALLENGING. - RETCODE-> $rc \n"); www_challenge("i2cat.net", "0"); switch($rc){ case -5: xlog("L_INFO", "-> 500: internal server error"); sl_send_reply("500", "Internal Server Error"); case -4: xlog("L_INFO", "-> 404: credentials not found"); sl_send_reply("404", "Credentials Not Found"); case -3: xlog("L_INFO", "-> 400: bad request - stale nonce"); sl_send_reply("400", "Bad Request"); case -2: xlog("L_INFO", "-> 401: invalid password"); sl_send_reply("401", "Invalid Password"); case -1: xlog("L_INFO", "-> 401: invalid user"); sl_send_reply("401", "Invalid User"); default: xlog("L_INFO", "-> 401: unauthorized"); sl_send_reply("401", "Unauthorized"); } } Buuuuuuuuuuuuut... I got that in the debug of Kamailio: *Code:* 4(31099) DEBUG: auth [api.c:95]: auth: digest-algo: MD5 parsed value: 1 4(31099) DEBUG: auth_radius [sterman.c:271]: radius_authorize_sterman(): Success 4(31099) WARNING: auth_radius [authorize.c:89]: RADIUS server did not send SER-UID attribute in digest authentication reply 4(31099) DEBUG: auth [challenge.c:102]: build_challenge_hf: realm=' i2cat.net' 4(31099) DEBUG: auth [challenge.c:113]: build_challenge_hf: qop='auth' 4(31099) DEBUG: auth [challenge.c:236]: auth: 'WWW-Authenticate: Digest realm="i2cat.net", nonce="TWZJLk1mSAKFVzL0b+dVPzkuyyAnZHQs", qop="auth" I guess it has something to do with this SER-UID attribute and thus something about the dictonary? It is weird seeing that the radius server says 'ok' but then openser is not authenticating it. I need some clues! Thank you!. -- Pablo Ros

rtpproxy and connection information field
by Dominguez Jover, Ricardo 01 Mar '11

01 Mar '11

Hi all, I'm using rtpproxy 1.2.1 and kamailio. RTPproxy is working fine in almost every case. However I have a problem with some call. When softphone A using sip2sip.info account calls softphone B using my Kamailio server account, the Kamilio receives SIP packets from IP1 (81.23.228.129). The invite packet has IP2 (81.23.228.150) in the conecction information field (c=IN IP4 81.23.228.150): INVITE sip:12345@xxxxxxxx.xxx;transport=udp SIP/2.0 Record-Route: <sip:81.23.228.129;lr;ftag=d9e99adf;did=e81.3538c317> Via: SIP/2.0/UDP 81.23.228.129;branch=z9hG4bKd14b.12802794.0 Via: SIP/2.0/UDP 192.168.xx.xx:7964;received=88.xx.xx.xx;branch=z9hG4bK-d8754z-8ba1b4b47e37bb89-1---d8754z-;rport=7964 Max-Forwards: 69 Contact: <sip:54321@88.xxx.xxx.xxx:7964;transport=udp> To: "2205"<sip:12345@xxxxxxxx.xxx> From: "R sip2sip"<sip:54321@sip2sip.info>;tag=d9e99adf Call-ID: OGE5MTFiMzljZjE0NTYxN2M0N2VkZjgzNDRhMzE2ZTA. CSeq: 2 INVITE Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, NOTIFY, MESSAGE, SUBSCRIBE, INFO Content-Type: application/sdp Supported: replaces User-Agent:xxxxxxxxxxxxxxxxxxxxxxxxx Content-Length: 279 v=0 o=- 12943454020854250 1 IN IP4 192.168.xxx.xx s=xxxxxxxxxxxxxxxxxxxx c=IN IP4 81.23.228.150 t=0 0 m=audio 52854 RTP/AVP 107 0 8 18 101 a=rtpmap:107 BV32/16000 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=yes a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=sendrecv Then Kamilio translates "c=" IP address to my RTPproxy IPaddress and sends the INVITE to softphone B. After the OK softphone B sends RTP packets to the RTPproxy as specified in the "c=" field, however the RTPproxy sends RTP packets to IP1 instead of send packets to IP2. How can I tell the RTPproxy to send packets to IP2 (the one in the c= field?) Thanks, Ricardo Dominguez

Hi! Using kamailio 3.1.1, I failed to use '%' as described in the core cookbook. Using 'mod' instead seems to work. regards Klaus

Kamailio Installation
by Suresh Bhandari 01 Mar '11

01 Mar '11

Hello Community, I am new to Kamailio, and this list as well. I am trying to install Kamailio 3.1.2, but I am getting too many errors. I have fixed some but still not getting the way. I am using Red Hat Enterprise Linux (RHEL) 5, and /usr/local directory. When I ran the following command: make group_include="standard standard-dep mysql" include_modules="carrierroute peering" install it prompted not found error for the file docbookx.dtd, I found it (modules/auth/auth.xml, and modules_s/acc_syslog/acc_syslog.xml) and fixed it as it was errorenous URL location. For reference earlier it was http://www.oasis-open.org/docbookid/id/g/4.5/docbookx.dtd, which I changed to http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd. Now when I run the previous command again, I am getting the follwing errors: *nsgmls:<URL>http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd:116:17:E: "X20AC" is not a function name* If I ignore this, and continue, I am not able to find the "sip-router" service in /etc/init.d. The entire errors is attached here. Please help me solve the issue. TIA Suresh

no private memory left after mi mt_reload command
by Javier Gallart 28 Feb '11

28 Feb '11

Hi all we are running kamailio 3.1.1. Basically for every call it has to query a mtree that is reloaded every 15 minutes. The mtree table is about 4M records and is stored in a Pgostgres database. For the reload we use the command mi mt_reload embedded in a xmlrpc request. The code for this is: route[XMLRPC]{ if (method == "POST" || method == "GET") { if (search("^User-Agent:")) { xlog("xmlrpc request\n"); set_reply_close(); set_reply_no_connect(); # optional dispatch_rpc(); } exit; } } This server has been running with no issued for some weeks now, but at some point during the weekend the mi command started to fail. This is what the logs show: ERROR: <core> [db_res.c:181]: no private memory left ERROR: db_postgres [km_res.c:225]: could not allocate rows ERROR: db_postgres [km_dbase.c:280]: failed to convert rows ERROR: mtree [mtree_mod.c:627]: Error while fetching result ERROR: db_postgres [km_dbase.c:318]: invalid parameter value ERROR: mtree [mtree_mod.c:738]: cannot re-load info from database I've restarted kamailio and now it's working fine. Should we increase the private memory? On the other hand, we'd like to detect this failure condition on the script and act accordingly (for instance sending an email with an alarm message), is there anyway to do this? Thanks in advance Regards Javier
