  Why Random callerid setting required             In call centers sometimes they need to show random callerids for each call, which are generated by autodiallers or predictive diallers ,so customers wont see that call is from same center. in this blog i will show two methods to set random callerid  in asterisk or vicidial or goautodial based diallers, pbx. Option 1 :   using  RAND function in asterisk         RAND Function can be used in a scenario , if you have a range of DID's  like  40004001 to 40004999 pick any one number randomly within this range and set it has callerid. Before entering the dialplan , let me explain little bit about RAND function Asterisk Function RAND Synopsis: Choose a random number within a range Description: RAND(min,max) choose a random number between min and max , min default to 0 if not specified,  while max may be upto 2...

  There are three ways to restore corrupted InnoDB databases (you should decide which one to choose, sometimes You will need to use not only one): manually importing files to newly created database using Percona InnoDB recovery tools using innodb_force_recovery For above methods You will need to have files from Your datadir (for example: /var/lib/mysql), so copy it somwhere. Manually importing files For this method You need to have ibd files from MySQL’s datadir and You need to know how was the table created (whole create command). First step is to create new database, so login to MySQL and create it: create database corrupted; Now create table: use corrupted; CREATE TABLE ` maintenances ` ( ` maintenanceid ` bigint unsigned NOT NULL, ` name ` varchar ( 128 ) DEFAULT '' NOT NULL, ` maintenance_type ` integer DEFAULT '0' NOT NULL, ` descriptio...
