Migrating OpenSIPS location table to Kamailio format

This applies to OpenSIPS 1.4.4 and Kamailio 3.3.2, although it may work with other versions as well.

OpenSIPS->Kamailio:

Integrics does the following on sip0 and sip1: cpan Math::BigInt::FastCalc enswitch install kamailio-ha vi /etc/kamailio/kamailio.cfg # and set the database URL

Update haresources on sip0 and sip1: change "opensips" to "kamailio" in /etc/ha.d/haresources

Stop OpenSIPS on sip0: sudo /etc/ha.d/resource.d/opensips stop

Remove OpenSIPS init script on sip0 and sip1: sudo rm /etc/ha.d/resource.d/opensips

Update version for location table on enswitchbd0: update version set table_version='5' where table_name='location';

Convert OpenSIPS version of location table to work with Kamailio on enswitchdb0:

RENAME TABLE location TO location_old_opensips;

CREATE TABLE `location` (

 `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 `ruid` varchar(64) NOT NULL DEFAULT ,
 `username` varchar(64) NOT NULL DEFAULT ,
 `domain` varchar(64) DEFAULT NULL,
 `contact` varchar(255) NOT NULL DEFAULT ,
 `received` varchar(128) DEFAULT NULL,
 `path` varchar(128) DEFAULT NULL,
 `expires` datetime NOT NULL DEFAULT '2020-05-28 21:32:15',
 `q` float(10,2) NOT NULL DEFAULT '1.00',
 `callid` varchar(255) NOT NULL DEFAULT 'Default-Call-ID',
 `cseq` int(11) NOT NULL DEFAULT '1',
 `last_modified` datetime NOT NULL DEFAULT '1900-01-01 00:00:01',
 `flags` int(11) NOT NULL DEFAULT '0',
 `cflags` int(11) NOT NULL DEFAULT '0',
 `user_agent` varchar(255) NOT NULL DEFAULT ,
 `socket` varchar(64) DEFAULT NULL,

 `replicate` int(10) unsigned NOT NULL DEFAULT '0',
 `state` tinyint(1) unsigned NOT NULL DEFAULT '0',
 PRIMARY KEY (`id`),
 KEY `account_contact_idx` (`username`,`domain`,`contact`)

) ENGINE=InnoDB DEFAULT CHARSET=latin1 SELECT * FROM location_old;

Add link for Kamailio init script on sip0 and sip1: sudo ln -sf /opt/enswitch/current/etc/init.d/debian/kamailio /etc/ha.d/resource.d/kamailio

Start Kamailio on sip0: sudo /etc/ha.d/resource.d/kamailio start

Test calls on sip0:

Run hb_takeover on sip1 and test: /usr/share/heartbeat/hb_takeover

Run hb_takeover on sip0 and test again: /usr/share/heartbeat/hb_takeover

Kamailio->OpenSIPS:

Update haresources change "kamailio" to “opensips” in /etc/ha.d/haresources

Stop Kamailio: sudo /etc/ha.d/resource.d/kamailio stop

Remove Kamailio init script: sudo rm /etc/ha.d/resource.d/kamailio

Update version for location table update version set table_version='1004' where table_name='location';

Convert Kamailio version of location table to work with OpenSIPS: RENAME TABLE location TO location_old_kamailio;

CREATE TABLE `location` (

 `username` varchar(64) NOT NULL DEFAULT ,
