Is there something like "silence detect hangup"
by Stoyan Mihaylov 13 Feb '12

13 Feb '12

Problem - if connection drop, call can persist. In Asterisk there is silencedetecthangup - which should cause hangup, if there is full silence for desired period of time. Unfortunately it does not hangup. I mean: SIP client 1 ->Kamailio -> Asterisk ->Kamailio -> SIP client 2 If I drop connection for one of SIP clients, I expect call should be automatically hangup after a time I set (20 sec). But call persists. In worst case - if connection drops for both clients, call will persist until Asterisk is restarted. I will continue to look how to solve problem with Asterisk, but I am curious if this can be done from Kamailio also. If I can cancel call from both places - it will be great. I need to ensure that if something wrong happens, call will be dropped within 30 sec maximum. Stoyan

Is exec module ignoring time_to_kill parameter?
by Miguel Baptista 13 Feb '12

13 Feb '12

Hello, I am running kamailio 3.1.3 and I am making some tests with the exec module. I am running a "dummy" script and it worked like a charm. Now, I am testing what happens when the script takes "too much time" to return a result. According to exec module documentation the/ time_to_kill /parameter should take care of it. *time_to_kill* (INTEGER) /Specifies the longest time a program is allowed to execute. If the time is exceeded, the program is killed. / BTW ... I am assuming /time /is in milliseconds. I think the documentation should refer the time units. Apparently kamailio ignores this parameter (or it doesn't work as I am expecting). No matter which value I assign to /time_to_kill/, kamailio doesn't kill the script and waits for the script to finish. In the meanwhile some SIP timers are triggered ... resulting into a failed call. The test I am doing is quite simple. For incoming INVITEs, use a external script to check the status of a specific test user, if it returns the keyword "busy" sends it to voicemail otherwise route the INVITE to the local user. The test script returns a result after about 8 seconds. Shouldn't the /time_to_kill/ be triggered and stop the script? Here goes some relevant parts of my configuration. In attachment I am sending the kamailio log with a debug value of 4. /# ----- exec params -----/ /modparam("exec", "time_to_kill", 10)/ /# --- exec params end -----/ /#route just to check the exec module route[TESTEXEC] { xlog("L_INFO", "TESTEXEC: Entered ($rU)\n"); if ($rU == "miguel") { $var(calendarTMP)="/root/" + $rU + "_test.pl"; exec_avp("$var(calendarTMP)", "$avp(s:test)"); xlog("L_INFO", "TESTEXEC: Returned value is $avp(s:test)\n"); if ($avp(s:test) == "busy") { $ru = "sip:userbusy@" + ASTSERVIPPORT; # Voicemail route(RELAY); } } xlog("L_INFO", "TESTEXEC: Exiting ($rU)\n"); return; } / Regards, Miguel Baptista

TCP keepalive on server and client
by Yufei Tao 13 Feb '12

13 Feb '12

Hi I want to use TCP keepalive to detect dead connections between Kamailio and my SIP clients. I've got some questions about this: 1. If I enable it on Kamailio by setting for example: tcp_crlf_ping = yes tcp_keepalive = yes tcp_keepidle = 60 tcp_keepintvl = 10 tcp_keepcnt = 3 >From what I read by gooling, that means Kamailio only responds to the crlfcrlf sent by the client, but can't be configured to send the crlfcrlf. Is this right? 2. On my client, if I use setsockopt to set the corresponding values: SO_KEEPALIVE TCP_KEEPCNT TCP_KEEPIDLE TCP_KEEPINTVL would it make the client send crlfcrlf? The reason I'm confused is, with these settings, if Kamailio can only respond to crlfcrlf, but not send, then would the client only respond too, as in 1. and 2., they seem to configure the same set of parameters? Please help me clarify this. Thanks very much! Yufei -- Yufei Tao Red Embedded This E-mail and any attachments hereto are strictly confidential and intended solely for the addressee.

Howto configure to use SQLITE
by Perazim 13 Feb '12

13 Feb '12

I am a new user and am trying to configure kamailio to use SQLITE instead of MYSQL. I see that SQLITE option is rather new and maybe not as documented as MYSQL. I am running on fedora 14 and have installed MYSQL3 from rpms. Kamailio I built from sources because I need the SQLITE support. What kamailio.cfg and kamctlrc parameters do I need to change to do this? I have already set these in kamctlrc: ... ## database type: MYSQL, PGSQL, ORACLE, DB_BERKELEY, DBTEXT, or SQLITE # by default none is loaded # # If you want to setup a database with kamdbctl, you must at least specify # this parameter DBENGINE=SQLITE ## database host DBHOST=localhost ## database name (for ORACLE this is TNS name) # DBNAME=openser ... and ran: kamdbctl create openser and kamctl add user1 password1 successfully. Now, it appears that I need to change kamailio.cfg for SQLITE. Can I simply edit this file substituting SQLITE for MYSQL and loading the SQLITE module? How about this part: ... ####### Defined Values ######### # *** Value defines - IDs used later in config #!ifdef WITH_MYSQL # - database URL - used to connect to database server by modules such # as: auth_db, acc, usrloc, a.s.o. #!define DBURL "mysql://openser:openserrw@localhost/openser" #!endif ... Will this URL work with SQLITE? Thanks in advance, Perazim

Detection of broken TCP connections to clients
by Yufei Tao 10 Feb '12

10 Feb '12

Hi When clients register to Kamailio over TCP/TLS, if I set tcp_connection_lifetime to be quite small, like 30 seconds, and let clients send refreshes every 20 seconds, for example. When client crashes or have network problems, the TCP connection with Kamailio will be closed by the server after 30 seconds of being idle. My question is, is there a way of letting Kamailio tell which user the broken TCP connection belongs to, and then remove the user from the location table and update presence information etc? The reason I want this is, if a user publishes its status of being online with expiring time of 1 hour, but then crashed, then the location table entry and presence information of this user would be wrong for the rest of the hour. How do I get around this? I assume server can send periodic OPTION messages but that would be a bit expensive. Thank you very much!

Re: [SR-Users] dialog vars issue
by Daniel-Constantin Mierla 09 Feb '12

09 Feb '12

Hello, back on mailing list ... I think I got it -- the acc record is written when 200 ok for invite is sent out, dialog is processing it before. Therefore dialog structure is updated with to-tag from the reply, but the building of acc record is executed using the INVITE request taken from transaction, where is no to-tag (acc internal design). This results in failing getting the dialog, because of to-tag mismatch. I will send a patch soon.
