Request-URI in fail route
by Jan Klepal 20 Mar '12

20 Mar '12

Hello, I am trying to set simple no-answer forward scenario: Alice calls Bob and after timeout 5s forward to Carol (and additionally Carol timeout forward to Dave). I am using Kamailio 3.2.2 default config. There is part of routing logic for no-answer forwarding: route[RELAY] { if(is_method("INVITE")) { t_set_fr(5000); t_on_branch("BRANCH_ONE"); t_on_reply("REPLY_ONE"); t_on_failure("FAIL_ONE"); } if(!t_relay()) { sl_reply_error(); } } branch_route[BRANCH_ONE] { $avp(divert) = $null; if($rU == "bob") { $avp(divert) = "carol"; } # second problem if($rU == "carol") { $avp(divert) = "dave"; } } failure_route[FAIL_ONE] { if($avp(divert) != $null) { add_diversion("no-answer"); $rU = $avp(divert); route(LOOKUP); route(RELAY); } } First problem I encountered is that I can't check $rU in failure_route (it is always set to original Request-URI - bob). Is this normal behavior or am I missing something? Because of that I have to set divert destination in branch route. Second problem is when Carol's no-answer forward to Dave happens. Then add_diversion adds invalid diversion header because it uses Request-URI which is still set to bob. Kind Regards, Jan

Hi, does kamailio mitigate server overload???If yes how is that?? Is there a setting for high water mark or something?? Regards, Vineet Menon

FW: Unsuccessful call using DRouting - Request Timeout
by Fatima Chahrour~Vanrise Support 20 Mar '12

20 Mar '12

Dears, I started my lab on VMware (debian lenny) where I installed Kamailio 3.2 and started drouting configuration. I'm using 2 PCs each having an x-lite softphone and the Kamailio on the vmware all connected locally. My primary test is to make a call from x-lite on PC (192.168.111.11) to x-lite on PC (192.168.111.226) through Kamailio\ drouting modules (192.168.111.139). What is happening is that when I call 9611558800, for example, am getting 'Calling' message on PC x-lite followed by 'Call Failed: Request Timeout' after a certain time. Attached is my routing logic script, and ngrep for the call that is failing. And my dr_tables data is : dr_rules: 4, '0', '9611', '', 0, '', '#3', 'Lebanon Fix' dr_gw_lists: 3, '5', 'Test Call' dr_groups: 3, '.*', '.*', 0, 'Everyone' dr_gateways: 5, 1, '192.168.111.226', 0, '', '', 2, 'PC1' I tried adding port number to the gateways, remove '#' and add 5 in the dr_rules, remove the "0" from do_routing in the script, but with no success. Reading some related documents and books, I found that all scenarios using drouting have gateways as media servers (Asterisks) . So my question: is this a must, to have a media proxy even using my above primary enviroment? If not, can you please help me finding my mistake that prohibit the call's success(ringing)? Thanks in advance. F.Chahrour

Dispatcher and round-robin ignoring priorities?
by Øyvind Kolbu 20 Mar '12

20 Mar '12

Our PSTN provider has three servers. Two of them are located in our town, and we prefer them, and the last one much further away. We can use them interchangeably. >From our dispatcher file: # 10: PSTN 10 sip:preferred1.example.com:7476 0 5 10 sip:preferred2.example.com:7476 0 5 10 sip:third.example.com:7476 0 4 In our dispatch router we use 'ds_select_dst("10","4")'. Then the round-robin algorithm evenly distributes the load on all three of them, instead of round robin on the ones with priority 5 and fallbacking to priority 4. Is the unconditional round robin as excepted? When changing the selection algorithm to "8", «use first destination», the dispatcher module correctly uses first "preferred2", then "preferred1" and then lastly "third". Why «first destination» is not the first one listed in the dispatcher file has always puzzled me.. # kamailio -V version: kamailio 3.2.1 (i386/linux) 31c991 flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 31c991 compiled on 08:08:06 Dec 6 2011 with gcc 4.1.2 -- Øyvind Kolbu

Presence question
by David 19 Mar '12

19 Mar '12

Hello, I am running a presence server. I am searching for a problem with my presence, and I have traced it down to this query : delete from active_watchers where presentity_uri='sip:test109@domain.tld' AND event='dialog' AND to_tag='f0253efb8005057b3cc0ab8fa35ff1d9-c961' This query is being sent to the database a few seconds after the initial subscribe is received. So the subscription only lasts in the database for a few seconds. I tried running level 3 error reporting ( hundreds of DEBUG ). I did not see any justification for query. Where is this query coming from ( source code/ config file )? Why is this subscription being deleted almost immediatly after it is setup ? Thanks, David Here is a sample request ( not the same as the one above, I did not capture the SIP at the same time as the SQL ) : U PROXYIP:5060 -> PRESENCEIP:5060 SUBSCRIBE sip:test109@domain.tld SIP/2.0.

Re: [SR-Users] XMPP module not passing subscribes coming from xmpp side

Hi Pavel, Many thanks for your reaction. Good to know about the issues, saved me some important time with troubleshooting. Will try to find alternatives in this case since I already found some other limitations which stop me in having an enterprise solution. Have a good one!

message offline store questions...
by Krishna Kurapati 19 Mar '12

19 Mar '12

Hi, I am using msilo module to store offline message. I am sending back "202 pending" when the message is stored (m_store) However, when I message delivered (m_dump), how do I inform the sender that the message is successfully delivered? Also, how do I handle if the sender if offline when I try to inform about the delivery of the message. I think I need offline notify store to handle this condition. Instead of removing the message from the silo table upon receipt of 200 OK from the receiver, I am thinking keep the message there until the NOTIFY is successfully delivered to the sender. In effect, the silo table in the database function as offline message and notify store. I reviewed module_k/msilo source code, and the functionality that I need seems missing. I am thinking of two approaches. 1) Extend the msilo module to implement the feature, if more people need it, then I can submit the changes. 2) Write sqlops + lua script to address the missing function. In either case, I am thinking of storing the callid of the original message (possibly in silo table?) in the database and sending the NOTIFY with the callid to the sender. I would like to extend the silo table with two columns: 1. the callid of the message 2. flags to indicate status of the delivery of the message. Appreciate your comments, suggestions and alternatives. Thanks Krish Kura

Dear Daniel, Thanks for your reply.. I'd like to ask you too if my script in my first post that am using in the routing area is correct? I found file named core in the '/' location as you mentioned. When I open it using #cat core, the opened file go crazy and writes strange characters and it ending with the below: /usr/local/sbin/kamailio-P/var/run/kamailio.pid-f/usr/local/etc/kamailio//ka mailio.cfgSSH_AGENT_PID=3234GPG_AGENT_INFO=/tmp/seahorse-jKaZEU/S.gpg-agent: 3246:1TERM=xtermDESKTOP_STARTUP_ID=SHELL=/bin/bashGTK_RC_FILES=/etc/gtk/gtkr c:/home/vanrise/.gtkrc-1.2-gnome2WINDOWID=33580848USER=rootGNOME_KEYRING_SOC KET=/tmp/keyring-ZKxFck/socketSSH_AUTH_SOCK=/tmp/keyring-ZKxFck/sshUSERNAME= vanriseSESSION_MANAGER=local/debian:/tmp/.ICE-unix/3188MAIL=/var/mail/rootPA TH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/DESKTOP_SES SION=defaultGDM_XSERVER_LOCATION=localPWD=/usr/local/etc/kamailioLANG=en_US.

It is a strange location unless you started with -w /var/log. The core file is named usually 'core' or core.pid (replace pid with same number, like, 'core.1234'). The default location in in '/' unless there is a different location set via -w or enforced by operating system (e.g., mac os x puts it in '/corefiles'). Hope it helps to locate the core file and send the backtrace.
