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

Re: [SR-Users] Question on the debug change level command with 5.0.x

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

Presence + RLS + XCAP
by Paul Smith 23 Mar '17

23 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: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 <sip:org1a@*****.co.uk>>;tag=wwasqc6lmb t: <sip:org1a-contacts@****.co.uk <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 <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 <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 <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 <sip:org1a@****.co.uk>>;tag=wwasqc6lmb t: <sip:org1a-contacts@*****.co.uk <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 <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...

Status of db_cassandra
by Markus Bönke 23 Mar '17

23 Mar '17

Hello, We are thinking about to use kamailio as a sip registrar with cassandra as db backend. As I can see in the documentation for kamailio 5.0 it is only tested with Casandra 1.1.6 and 1.0.1, current version is 3.10 in the meantime. Is anyone using this module with newer versions of Cassandra? Is it stable? Thanks and regards Markus

when match_exp of dp 100 is ^#test and repl_exp is sip:$rU@$rd this code: xlog("L_INFO", "****** ru = $ru\n"); dp_translate(100, "$rU/$var(res)"); xlog("L_INFO", "****** res = $var(res)\n"); produces: Mar 22 08:21:17 lohi /usr/bin/sip-proxy[7543]: INFO: ****** ru = sip:#test@test.tutpro.com Mar 22 08:21:17 lohi /usr/bin/sip-proxy[7543]: INFO: ****** res = sip:$rU@$rd -- juha

getting source IP from Contact header
by Ali Taher 22 Mar '17

Hello everyone, I'm trying to get the host part from the contact header in the sip invite packet. Following is the contact header format: Contact: <sip:user_name@192.168.1.1:5060> What I want as result is 192.168.1.1 I searched among the pseudovairables and found $ct variable which reference to the body of contact header. (<sip:user_name@192.168.1.1:5060>) Is there a way to get directly the host (192.168.1.1) without applying transformation at the level of $ct. If not what transformation can achieve it. Thanks in advance. Regards, Ali
