Kamailio Registration load Issue
by Jade SZ 28 Mar '17

28 Mar '17

Hi Guys, I am running a simple REGISTER load test on: 1) Kamailio sever with 2 cores - mem 5G 2) Kamailio server with 4 cores - mem 16G Both are EC2 instances. At -r = 500 i.e. 500 reg/sec sipP test works fine with very few re-trans. But when i increase it to 800 reg/sec it starts retransmissions in bulk. I don't see server's CPU, load-avg or memory shooting. Running everything by default, even using kamctl to start the instance. So I have not tuned any params yet. My main concern is how can I make server choke and get its actual capacity, and avoid these retransmissions as apparently kamailio is not even utilizing 2 cores and CPU usage is under 10 always. Results of both server is same i.e. 500 reg/sec max so I am sure there is some problem that needs a fix, but need some hints here. Also used multiple SIPp's to rule out if it is SIPp issue, but after 500 I see same problem. Regards, JSZ

new keepalive module ?
by Guillaume Bour 28 Mar '17

28 Mar '17

Hi all, I would like to implement destinations keepalive in drouting module (as it is done in dispatcher). But instead of duplicating what's implemented in dispatcher, I think it would be more clever to create a new module dedicated to pinging destinations, and to plug drouting, dispatcher and other modules to this new one What's you opinion about that ? Cheers, Guillaume

Presence + RLS + XCAP
by Paul Smith 27 Mar '17

27 Mar '17

Hi I am struggling to figure out how to build and test an integrated presence server with Resource-List (rls.so) and XCAP (xcap_server.so). I am confused about what is meant to happen and how to debug it. Not sure if I am suffering from incompatibilities, configuration errors, or bugs… I have not found an up to date guide on configuring an integrated presence, rls, xcap server so I have used old tutorials, module documentation and some course code review … but I’m pretty confused now! I am using Snom phones and Jitsi (on Mac) to test. I have a kamailio Registrar which proxies all presence messages to the separate kamailio 4.2 Presence server. REQUIREMENT : Contact Presence ============================= I would like to get a SUBSCRIBE from the Snom phone to subscribe to a contact-list resource list, and to receive a NOTIFY with all of the presence states for those contacts. Relevant snom settings? Contact List URI: this generates a SUBSCRIBE with event:presence I believe that: ========== presence module should be managing the individual user presence and dialog states xcap module should allow me to use HTTP / curl to edit the resource lists rls module should be managing the mapping from a resource list subscription to the individual presence states and generating the aggregated NOTIFY messages. each device should then be able to SUBSCRIBE to a resource list uri and then receive an aggregated NOTIFY for all of the watched entities. Current status: =========== SUBSCRIBE sip:org1a-contacts@*****.co.uk SIP/2.0 v: SIP/2.0/UDP 192.168.1.15:59594;branch=z9hG4bK-qllzlgs3xf43;rport f: <sip:org1a@*****.co.uk>;tag=wwasqc6lmb t: <sip:org1a-contacts@****.co.uk> i: 313439303236383530323234313530-x3hlb3j6b5ef CSeq: 1 SUBSCRIBE Max-Forwards: 70 User-Agent: snomD375/8.9.3.46 m: <sip:org1a@192.168.1.15:59594>;reg-id=1 Event: presence Accept: application/pidf+xml, application/rlmi+xml, multipart/related Supported: eventlist Expires: 3600 l: 0 … auth handshake SIP/2.0 202 OK Record-Route: <sip:10.210.160.13;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes> Record-Route: <sip:**pubip**;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes> v: SIP/2.0/UDP 192.168.1.15:59594;received=**recvip**;branch=z9hG4bK-8wufiv1ua3ne;rport=60554 f: <sip:org1a@****.co.uk>;tag=wwasqc6lmb t: <sip:org1a-contacts@*****.co.uk>;tag=a6a1c5f60faecf035a1ae5b6e96e979a-d30e i: 313439303236383530323234313530-x3hlb3j6b5ef CSeq: 2 SUBSCRIBE Expires: 3600 Contact: <sip:10.210.160.16:5060;transport=udp> Server: kamailio (4.2.0 (x86_64/linux)) Content-Length: 0 … and then the snom receives an empty NOTIFY.

Or does rls.so infer the relationship using the URI? When I use jitsi to manipulate its contact list it only inserts 2 rows into the xcap table and I cannot get a SIP Subscribe to connect to that resource list either. Question : What should the curl PUT commands and XML docs look like to build a valid RLS service (is there a good example anywhere)? Question : Is there an example config or doc anywhere showing how to build integrated presence, rls, xcap? Question : Has anyone got this working with Snom and or other handsets… the standards and implementations seem vague / inconsistent? Note: There is another Snom setting (Extension Monitoring Call Pickup List URI:) which produces a SUBSCRIBE with Event:dialog but which should allow a button/lamp/callpickup/BLF for the buddy contact. I’d like to get that working too, but recognise that rls.so does not handle dialog messages by default, so I’m starting with Presence... Paul

Important problem with this test : if ($var(i:maxRangeInx)==$null)
by Ginhoux, Patrick 27 Mar '17

27 Mar '17

Hi, I'm continue my job to 'migrate' my 3.3.1 kamailio.cfg script on a RHEL 6.2 server to the 5.0.x kamailio version on a RHEL 7.1 server, and I encounter a major problem with the '== $null' test in the script. My original script (3.3.1) contains this sequence : $var(i:rangeInx)=0; $var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange"); xlog(" imbxRangeInx value before test : '$var(i:maxRangeInx)' "); if ($var(i:maxRangeInx)==$null) { $var(i:maxRangeInx)=99; } xlog(" imbxRangeInx after test : '$var(i:maxRangeInx)' "); ==> The results are : imbxRangeInx value before test : '0' imbxRangeInx value after test : '99' I run the same script on my new server and I get '0' before and after the test. I attempted another kind of test to try to figure out where the problem is. So I write the simple test (with kamailio 5.0.x) : $var(i:rangeInx)=0; $var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange"); $var(toto) = $null; if ($var(toto) == $null) xlog ("toto true"); else xlog ("toto false"); The result I got is always 'toto false'. So it appears to me that the test '== $null' doens' that gives a good result with kamailio 3.3.1, doesn't return the same with kamailio 5.0.x. That is a major issue for me and it let me confused about the possibility to move to kamailio 5.0.x. Have people an idea / explanation, why this issue ? Cordialement Patrick GINHOUX

Cannot yum download from download.opensuse.org, no mirrors
by Shadowy Man 27 Mar '17

27 Mar '17

This is only happening for one particular block of IP's. I can download from other blocks. I suspect it is being done on the download.opensuse.org end for some reason. It appears to be the entire xx.xx block of which I only use a few addresses from. I will probably have to try contact them about it. What I would like to ask is why Kamailio does not have any mirrors? If there were then this would not be a problem. It would just failover.

Regex module having trouble with large regex expressions in kamailio 4.4.5
by Tim Balmer 24 Mar '17

24 Mar '17

Hi, I discovered some strange behavior from the regex module yesterday (kamailio version 4.4.5). For example we have the phone number 0033755500381 that we try to match with the following kamailio code: #!define REGEX_FF_NEG_INTERNATIONAL "6" ... if (pcre_match_group("$rU", REGEX_FF_NEG_INTERNATIONAL)) { # Do something } When the content of our regex groups file is like this: [6] ^(\+|00)3(0690|0693|0694|0695|0697|0698|0699|36|37|4160|46|47|51160|511691|511693|511696|511891|511893|511896|513|516091|5160921|516093|516096|516391|516392|516393|516396|516591|516592|516593|516596|516691|5166921|516693|516696|5191|5192|5193|5196|538|54388|543 89|546|5475|5477|548|567117|5672|5677|5679|5692|5694|5696|5698|5699|5795|5796|5797|5799|58299|584|5850|5948|5987|5988|5989|59988|59989|620|630|631|670|706|712|725|728|774|776|8591|8592|8595|8597|8598|8599|8620|8621|8630|8631|8640|8641|8643|8649|8650|8651|8660| 8661|8664|8670|8671|869814|906698|93) The above if statment is not matching, although it should match according to any regex validator (for example https://regex101.com/ ) But when I split the above regex in smaller parts, like this: [6] ^(\+|00)306(90|93|94|95|97|98|99) ^(\+|00)336 ^(\+|00)337 ^(\+|00)34160 ^(\+|00)346 ^(\+|00)347 ^(\+|00)351(160|1691|1693|1696|1891|1893|1896|3|6091|60921|6093|6096|6391|6392|6393|6396|6591|6592|6593|6596|6691|66921|6693|6696|91|92|93|96) ^(\+|00)3538 ^(\+|00)354(388|389|6|75|77|8) ^(\+|00)356(7117|72|77|79|92|94|96|98|99) ^(\+|00)357(95|96|97|99) ^(\+|00)358(299|4|50) ^(\+|00)359(48|87|88|89|988|989) ^(\+|00)3620 ^(\+|00)363(0|1) ^(\+|00)3670 ^(\+|00)3706 ^(\+|00)3712 ^(\+|00)372(5|8) ^(\+|00)377(4|6) ^(\+|00)385(91|92|95|97|98|99) ^(\+|00)386(20|21|30|31|40|41|43|49|50|51|60|61|64|70|71|9814) ^(\+|00)3906698 ^(\+|00)393 Then the exact same regex module call as before does result in a match as expected. So to me it looks like the regex module is having trouble with large regex expressions, I did check the logs but there is nothing strange there, that means also the large expression is correctly loaded according to the logs while in fact it is not working. Checked the regex module documentation but there I cannot find any limits regarding to the size of invididual expressions. Is it me missing something or did I discover a bug in de regex module? Best Regards, Tim Balmer Edutel BV

No, you don't. The debugger module, among other things, allows to set the debug level per module.
