Help with Asterisk RT integration
by Jon Morby 28 Feb '13

28 Feb '13

Hi I'm trying to integrate a (K) front end cluster with an Asterisk back end cluster and Asterisk RT (legacy system) I've followed the recipe at http://kb.asipto.com/asterisk:realtime:kamailio-3.3.x-asterisk-10.7.0-astdb (with one minor exception …) if (from_uri!=myself && uri!=myself) became if (uri!=myself) as with the original line in place we were able to spoof traffic from 3rd party sites and route out onto the PSTN (which I thought was bad) … anyway … The problem I'm seeing currently is that when a call is passed down a SIP trunk to an end user on the (K) platform we're losing the DNID Asterisk delivers the call to SIP/account/DNID (K) however just tries to deliver the call to DNID@domain which comes back as not found. I've had limited success hand coding aliases into the alias_db however we're still missing the DNID info and having to scrape it from the SIP To field (with a) limited success and b) fears of a support nightmare if we try and move existing customers onto the new platform). If we were to do this for real I'd either have to modify usrloc or try some perl_exec magic I'm guessing … (although it might be possible with a view on the existing sql database … but I'd rather not have to do that if there is a simpler way) I confess I'm struggling to get my head around the config and docs and hoped someone could point me in the right direction? For legacy reasons Asterisk needs to be in the critical path on this particular build … what I'm looking for is a simple recipe and some helpful pointers on how to implement it that will allow enable me to swing (K) into the path between our end user SIP devices and the existing asterisk back ends without losing the ability to deliver hundreds of numbers down a single SIP trunk to a subscriber, and that doesn't require them to make any changes on their end as they will still see the equivalent of SIP:${DNID}@example.com arriving on their PBX This should be simple, but I'm obviously missing something :) Help and pointers gratefully received -- Jon Morby FidoNet - the internet made simple! 10 - 16 Tiller Road, London, E14 8PX tel: 0845 004 3050 / fax: 0845 004 3051

Re: [SR-Users] SBC
by Keith 28 Feb '13

28 Feb '13

Hi All, So following a guide I have successfully setup Kamailio and FreeSwitch together working as an SBC. SIP registration with Kamailio and using FreeSwitch as the media server which in turn authenticates with users in Kamailio. I have managed to pass calls between users etc. So the next challenge is bolting 2 Asterisks servers behind this SBC and load balancing the media. As the SBC will be public facing I also have to consider NAT which I believe will be configured in FreeSwitch. I have had some fantastic advice in the past so just interested to get peoples views again. Thanks. -- Keith

Hello, the GIT master branch is again open for new development. Common testing period of releasing v4.0.0 has ended, if you have pending commits or personal branches to merge, you can go ahead. v4.0.0 will be released out of newly created branch 4.0.

How to remove custom header after adding one
by Mino Haluz 27 Feb '13

27 Feb '13

Hi, if I use append_hf() for adding my custom header to initial request, how I can remove this header later ? What I'm doing: 1) initial request: remove RPID header with remove_hf 2) initial request: add custom RPID header append_hf 3) after rerouting: in failure_route remove RPID header remove_hf 4) after rerouting: in failure_route add custom RPID header with append_hf The result of this, are 2 RPID headers, because remove_hf did not catch RPID header added in step 2, but I think the original one that was removed already in step 1. Thanks, Mino

GIT branch 4.0
by Daniel-Constantin Mierla 27 Feb '13

27 Feb '13

Hello, the GIT branch 4.0 has been created to host the release series for v4.0.x. It must take only bug fixes and documentation improvements related to the features existing at this moment in the branch. To get the branch locally, use: git clone --depth 1 git://git.sip-router.org/sip-router kamailio cd kamailio git checkout -b 4.0 origin/4.0 To push the local commits on remote repository: git push origin 4.0:4.0 Any fixes that have to get in the branch 4.0 should be committed first in master branch and then cherry-picked in this branch, in order to be able to track forgotten backports easier. Testing for 4.0 went very good so far, in few days we will probably sketch the path to the release day.

siremis CDR gneration procedure
by Klaus Darilion 27 Feb '13

27 Feb '13

Hi! IMO the siremis CDR generation procedure is buggy: CREATE PROCEDURE `kamailio_cdrs`() DECLARE inv_cursor CURSOR FOR SELECT src_user, src_domain, dst_user, dst_domain, dst_ouser, time, callid,from_tag, to_tag, src_ip FROM acc where method='INVITE' and cdr_id='0'; ... REPEAT FETCH inv_cursor INTO v_src_user, v_src_domain, v_dst_user, v_dst_domain, v_dst_ouser, v_inv_time, v_callid, v_from_tag, v_to_tag, v_src_ip; IF NOT done THEN SET bye_record = 0; SELECT 1, time INTO bye_record, v_bye_time FROM acc WHERE method='BYE' AND callid=v_callid AND ((from_tag=v_from_tag AND to_tag=v_to_tag) OR (from_tag=v_to_tag AND to_tag=v_from_tag)) ORDER BY time ASC LIMIT 1; IF bye_record = 1 THEN INSERT INTO cdrs (src_username,src_domain,dst_username, dst_domain,dst_ousername,call_start_time, duration,sip_call_id, sip_from_tag,sip_to_tag,src_ip,created) VALUES (v_src_user, v_src_domain,v_dst_user, v_dst_domain,v_dst_ouser,v_inv_time, UNIX_TIMESTAMP(v_bye_time)-UNIX_TIMESTAMP(v_inv_time), v_callid,v_from_tag,v_to_tag,v_src_ip,NOW()); UPDATE acc SET cdr_id=last_insert_id() WHERE callid=v_callid AND from_tag=v_from_tag AND to_tag=v_to_tag; END IF; SET done = 0; END IF; UNTIL done END REPEAT; ... 1. The UPDATE query will not UPDATE BYE records which were sent from CALLEE to CALLER. This can be easily fixed with: UPDATE acc SET cdr_id=last_insert_id() WHERE callid=v_callid AND ( (from_tag=v_from_tag AND to_tag=v_to_tag) OR (to_tag=v_from_tag AND from_tag=v_to_tag) ); 2. (minor) It does not consider reINVITEs. I know the default Kamailio config does not account reINVITEs, but I think when reINVITEs are accounted too, this can mess up the CDR generation. regards Klaus

Kamailio and Geoip
by Ian French 26 Feb '13

26 Feb '13

Hi list, I've been trying to get Kamailio using the geoip module to deny traffic from countries not matching certain sources, but I'm unsure of how to achieve this I've tried the below which failed. I'm trying to drop requests outside say 2 countries "AA" or "BB" geoip_match("$si", "src"); if($gip(src=>cc)!="AA" || $gip(src=>cc)!="BB") { xlog("L_INFO","SIP message from prohibited source $gip(src=>cc) (ip: $si)\n"); send_reply("403", "Forbidden"); exit; } else { xlog("L_INFO","SIP message from unprohibited source $gip(src=>cc) (ip: $si)\n"); } Can you tell me where I am wrong or how I can achieve this Thanks in advance Ian
