Hi list I don't understand prepaid logic calculation, because when my credit is 0 or lees than cost per second, the call is established equal $var(i_pulse) and $var(f_pulse) how this works????

Configuring TLS and WSS with Kamailio
by Kamrul Khan 25 Nov '14

25 Nov '14

Hi, Im trying to connect my WebRTC clietn to kamailio via WSS. I successfully connected it via WS but having trouble connecting it via WSS. My first issue is I get error messages while i try to compile TLS module(console log in the end of the document). But, still it creates tls.so file. So i copied the tls.so to my kamailio modules directory and then updated my kamailio configuration as below: #!define WITH_TLS . .listen=tcp:127.0.0.1:5061 listen=tcp:192.168.146.133:5061 . . #!ifdef WITH_TLS enable_tls=yes #!endif . . #!ifdef WITH_TLS # ----- tls params ----- modparam("tls", "config", "/usr/local/kamailio-devel/etc/kamailio/tls.cfg") #!endif Now, according to this mailing list,http://lists.sip-router.org/pipermail/sr-users/2013-March/077182.html : “when tls module is installed, a self signed pair of certificate-private key is generated in /usr/local/etc/kamailio” In my case, I dont even have the /usr/local/etc/kamailio directory. So, I followed http://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates to create my certificate and key. And updated my tsl.cfg, this is how my tsl.cfg looks like: [server:192.168.146.133:5061] method = TLSv1 verify_certificate = no require_certificate = no private_key = /etc/certs/sip.192.168.146.133/key.pem certificate = /etc/certs/sip.192.168.146.133/cert.pem ca_list = /etc/certs/demoCA/cert.pem [client:192.168.146.133:5061] verify_certificate = yes require_certificate = yes Then I restarted my kamailio server. And i get the following errors in my kamailio log: Im not sure what wrong im doing. Please help me: Oct 17 15:44:50 ubuntu kamailio: INFO: tls [tls_init.c:385]: init_tls_compression(): tls: init_tls: disabling compression...

Setting up a IMS Server Platform using Kamailio 4.2.x code
by Austin Einter 10 Nov '14

10 Nov '14

Hi All Last few days we have tried to setup Kamailio for IMS server setup. We have not been successful. Now we are planning to use Kamailio 4.2.0 code base (Latest) to setup Kamailio IMS setup. I am looking for a link/document, that gives proper step by step instructions how to setup Kamailio as IMS servers (P-CSCF, I-CSCF and S-CSCF). Can somebody kindly provide the official link or any other working link, that I can follow to setup P-CSCF, I-CSCF ,S-CSCF and HSS. Many thanks Austin

Re: [SR-Users] RPC uac.reg_info hangs second time
by Dan Christian Bogos 06 Nov '14

06 Nov '14

Hey Daniel, Thanks for your fast reply! I am using the 4.2.0 out of debian packages (not nightly). Will shift on nightly and retest. Not a big deal regarding 150 seconds, maybe it should be a good reason for async reloads (reply with the delay number of seconds when reload will happen). Reloads can be always implemented outside of kamailio but since everybody would need it I assume a more centralized approach would be useful. Anyway, thanks again!

using time stamp
by bob sacamano 03 Nov '14

03 Nov '14

hi, I am trying to see how long kamailio takes to process messages I saw the commands: set_time_stamp diff_time_stamp in older versions of kamailio but they dont seem to be available. I have been searching for info but have been unable to find anything. Is the command no longer available or is there some other way to use? thanks

Trouble with LCR removing $ru after upgrading to 4.1.6
by Will Ferrer 01 Nov '14

01 Nov '14

Hi We are having an odd issue with our LCR. This started after we upgraded from kamailio 4.1.0 to 4.1.6. Here is the situation: We populate our gw_uri_avp (stored in: $avp(i:709)) as follows: 16|1||||[gateway ip address]||5060||1|1. The $ru before running next gateway shows: sip:[destination number]@[our domain that the call came into]. This is how it should look before lcr occurs. Then we run next_gw(). We get these message in the logs during the running of next_gw DEBUG: lcr [lcr_mod.c:2156]: generate_uris(): r_uri <*1*[destination number]@[gateway ip address]:5060*1*>, dst_uri <> DEBUG: lcr [lcr_mod.c:2437]: next_gw(): added ruri_user_avp <[destination number]> DEBUG: lcr [lcr_mod.c:2473]: next_gw(): added flags_avp <1> DEBUG: lcr [lcr_mod.c:2480]: next_gw(): added tag_avp <> DEBUG: lcr [lcr_mod.c:2488]: next_gw(): added defunct_gw_avp <1253613379> The main thing to notice there is that there is now a 1 at the start and end of the r_uri shown in generate_uris. I am fairly certain those are new, and maybe related to what happens next. Immediately following the next_gw function running the $ru becomes: <null>, so of course the call doesn't go through. I have looked at the code for the lcr module and it looks like it wasn't changed in version 4.1.6. I found alot of other notes in the change log that had to do with the way uris are handled so it is possible one of those changes caused the problem. I am stumped currently. Any help any one can offer me would be very appreciated. All the best. Will Ferrer Swithsoft Inc

pipelimit rate question
by Alex Balashov 31 Oct '14

31 Oct '14

Hi, There does not seem to be a way to update the limits of pipes dynamically. If I don't use DB backing, there is no MI/RPC command to flush existing pipes and cause them to be recreated with reconstituted limits. If I use DB backing and add pipes to the pl_pipes table, an SQL update to the limit column does not influence existing pipes that have been loaded from the DB on startup. Am I missing something, or does the existing feature set of the module simply not allow this? Thanks, -- Alex Balashov - Principal Evariste Systems LLC Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ Please be kind to the English language: http://www.entrepreneur.com/article/232906

async workers causing unexplained high load average
by Alex Balashov 31 Oct '14

31 Oct '14

Another thing I have found is that having a certain amount of async workers running, even if they are not doing anything, appears to cause unexplained CPU load, even if the Kamailio instance is completely idle and not processing any calls. Here is the baseline load with no async workers: [root@centosity6 ~]# uptime 14:06:28 up 2 min, 2 users, load average: 0.01, 0.00, 0.00 If I start Kamailio with 1 async worker... modparam("async", "workers", 1) async_workers=1 14:07:59 up 3 min, 2 users, load average: 0.00, 0.00, 0.00 Still nothing. Now I try 2: 14:08:54 up 4 min, 2 users, load average: 0.45, 0.11, 0.04 14:08:59 up 4 min, 2 users, load average: 0.49, 0.12, 0.04 14:09:04 up 4 min, 2 users, load average: 0.53, 0.14, 0.04 14:09:09 up 4 min, 2 users, load average: 0.57, 0.15, 0.05 14:09:14 up 5 min, 2 users, load average: 0.60, 0.17, 0.05 14:09:19 up 5 min, 2 users, load average: 0.63, 0.18, 0.06 14:09:31 up 5 min, 2 users, load average: 0.69, 0.21, 0.07 14:09:37 up 5 min, 2 users, load average: 0.71, 0.22, 0.07 14:10:35 up 6 min, 2 users, load average: 0.89, 0.36, 0.13 14:11:07 up 6 min, 2 users, load average: 0.93, 0.42, 0.16 ... I don't have time right now to see if it will rise to infinity, but it just keeps going up. There are no SIP messages being received at all, and there is absolutely nothing going on. The ascent of the load average is much higher with >= 4 threads. I have 8 "CPUs" available from /proc/cpuinfo (quad-core processor with HyperThreading). When I attach strace to the PID of the Async Worker, there's nothing going on except the normal recvfrom() blocking wait: [root@centosity6 kamailio]# kamctl ps | grep Async which: no greadlink in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/) Process:: ID=11 PID=1559 Type=Async Task Worker Process:: ID=12 PID=1560 Type=Async Task Worker [root@centosity6 kamailio]# strace -p 1559 Process 1559 attached - interrupt to quit recvfrom(9, [root@centosity6 ~]# strace -p 1560 Process 1560 attached - interrupt to quit recvfrom(9, Nor do the other Kamailio threads seem to be doing anything unusual. 'ps aux' and 'top' show 0.0% CPU load on the Kamailio processes themselves, and 'iowait' shows the system as 98-99% idle. I suppose it's possible that this is a peculiarity of the testing environment: I am running this on CentOS 6.5 inside VirtualBox, which I think is KVM-based. I have not had a chance to duplicate this experiment in a different kind of execution environment yet. It's possible that the load average is simply being improperly indicated because of the VM environment. -- Alex Balashov - Principal Evariste Systems LLC Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ Please be kind to the English language: http://www.entrepreneur.com/article/232906
