Need example of Kamailio.cfg for a port mirror setup
by Nelson Pereira 17 Feb '12

17 Feb '12

I would like to know if someone can show me an example of there setup configuration in kamailio.cfg for capturing packets comming in from a mirror port. The reason I ask is that if I do a TCPDUMP on the server, I see all traffic to and from different sources on my Voice network. But when I use Homer SIPCAPTURE which uses Kamailio in the background, I only see traffic sent FROM my PBX but not seing the traffic comming back to it. I mean I only see one side of the call, yet TCPDUMP confirmed I see everything.... What am I missing ? Thanks NP

Re: [SR-Users] how to match exact string value in mtree (Uri Shacked)
by Javier Gallart 17 Feb '12

17 Feb '12

Hello Uri I had similar needs and I found the ndb_redis module more suited for that type of task. Instead of a tree you have a hash like this: tname tprefix tvalue. If you do a hget nts $avp(DID) and you get a not null value you have found your exact match. It works very well for me and the time it takes for that "query" is barely noticeable. Of course redis does not address items like persistence, etc the same way a rdbms does. Hope it helps.

ndb_redis module fails after a while
by Javier Gallart 17 Feb '12

17 Feb '12

Hi all I have started making some tests with the ndb_redis module. So far we have not stressed the module (no more than 5 HGET commands/second at maximum). It works well, but with at some point it starts failing. The failures are easily found because the logs always show this: INFO: <core> [main.c:811]: INFO: signal 13 received After that the redis value is always null. If I restart kamailio it starts working again. I've run kamailio with debug=4 but I haven't seen more useful information. On the redis side, I could find nothing in the logs either, the number of clientes connected is alway much less than the configured maximum, Any idea? On the other hand, if I restart redis we need to restart kamailio to restore the connections. Is the reconnection to redis on the roadmap? Thanks in advance Regards Javi

Loading huge amount of records from mysql takes time indeed. Maybe prefix matching will be added in redis in the future, or scripted server side in lua, as I understood it has such feature. Another option would be to add a custom command in kamailio like redis_cmd_pmatch() to do internally these prefix-based commands until a match, could simplify the config if it becomes something very popular. Also, I forgot about the other solution in kamailio - pdb module written by 1&1 for number portability: * http://kamailio.org/docs/modules/stable/modules/pdb.html Just mentioning it here for let it be known, if redis is working fine for you, makes no sense to look for other solutions.

CAcert root in Lumicall
by Daniel Pocock 17 Feb '12

17 Feb '12

I've been contemplating Daniel's earlier question about using the CAcert certificates with Lumicall sip5060.net should already accept mutual authentication from other Kamailio instances running with a CAcert certificate However, the Lumicall dialer itself will only connect to servers that are using a cert signed by a root CA trusted within Android. This applies to both the SIP and STUN over TLS support. It may be possible for me to embed the CACert root in the Lumicall package and create a custom trust manager - allowing Lumicall to work with any server using CAcert TLS certificates. Does anyone have any strong feelings about not doing something like that?

how to match exact string value in mtree
by Uri Shacked 17 Feb '12

17 Feb '12

Hi, I am using Mtree to match prefix numbers, some of them starts with 0 or characters like D for example. so, the mtree param is like this: modparam("mtree", "db_url", CFGDB) modparam("mtree", "mtree", "name=nts;dbtable=service_numbers_view;type=0;") modpmodparam("mtree", "char_list", "0123456789*+#YMDabcdefgh") modparam("mtree", "pv_value", "$avp(mtval)") modparam("mtree", "pv_values", "$avp(mtvals)") The thing is, that i tried all: if(!mt_match("nts", "$avp(DID)","1")) if(!mt_match("nts", "$avp(DID)","2")) if(!mt_match("nts", "$avp(DID)","0")) and lets say i have the both prefix in the nts mtree: 09555 09555333 And the prefix i search for is $avp(DID)=09555444 I allwasy get the 09555 because it is the longest match. I need exact match..... how do i do that?
