Mobile Number Portability Addon
Mobile number portability (MNP) enables mobile telephone users to retain their mobile telephone numbers when changing from one mobile network operator to another.
MNP Addon for MOR allows system owner to check number if it belongs to other network and if so - route it through different providers or bill it with different price.
Current implementation allows to save numbers in MySQL database on any server (possible not on local server).
Before each call MOR MNP Addon checks dialed number and if number is found in database - some prefix is added in front of it.
By prefix MOR can set different routing(LCR) or billing(Tariff) for this number. Localization rules should be used to perform these actions.
Detailed technique is described here: LCR/Tariff change based on call prefix
As Kolmisoft cannot make one unique database for all MNP services in all countries all over the world. MOR admin has to
manually enter numbers in MNP database (process described below) in order for this solution to work. mor_mnp database has
to contain only the necessary data (telephone numbers).
NOTE: It is important to take care of various number formats user can use to dial a number. As a solution to it is to insert MNP number into DB in several possible formats.
Installation
Do such steps:
1. Update MOR scripts:
rm -fr /usr/src/mor svn co http://svn.kolmisoft.com/mor/install_script/trunk/ /usr/src/mor
2. Run MNP installation script:
/usr/src/mor/sh_scripts/install_mnp.sh
3. Run script which will update Asterisk extlines to work with MNP database:
/usr/src/mor/test/scripts/asterisk/mnp_cfgs.sh
How to see if MNP works
Open Asterisk CLI. During the call check very first lines shown in CLI. In about 10th line you should be able to see lines like that:
-- Launched AGI Script /var/lib/asterisk/agi-bin/mor_mnp mor_mnp: mor_mnp: MOR MNP AGI script started. mor_mnp: Successfully connected to database. mor_mnp: Extension: 37012312345 mor_mnp: New extension: 37012312345 mor_mnp: MOR MNP AGI script stopped. mor_mnp:
If you cannot see it. Something is wrong with configuration.
Upgrade/Update
After MOR Upgrade or Update run /usr/src/mor/test/scripts/asterisk/mnp_cfgs.sh
Database
Config to DB in: /usr/local/mor/mor_mnp.conf
It should be MySQL database mor_mnp:
DROP TABLE IF EXISTS `numbers`; CREATE TABLE `numbers` ( `number` varchar(50) NOT NULL, `prefix` varchar(20) NOT NULL, PRIMARY KEY (`number`), UNIQUE KEY `number` (`number`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Make sure you have set correct MySQL permissions for mor_mnp database and also local or remote asterisk must have correct settings in /usr/local/mor/mor_mnp.conf . If your number is still not recognized, double check if you have it in your mor_mnp database!
An example how to set MySQL permissions:
GRANT REPLICATION SLAVE , REPLICATION CLIENT ON * . * TO 'mor'@'localhost' IDENTIFIED BY 'mor' WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;
GRANT ALL PRIVILEGES ON `mor_mnp` . * TO 'mor'@'localhost' WITH GRANT OPTION ;
How to use MNP
You need to insert two values in mor_mnp database. These values are number and prefix.
To manage mor_mnp database you can use PhpMyAdmin:
http://<your server IP>/moradmin
PhpMyAdmin login details can be found in file /root/phpMyAdminPassword
If after loging in to PhpMyAdmin, MySQL login page will appear, use these details to login to MySQL:
username: mor
password: mor
Now click "_mnp (1)" menu item on the left to select mor_mnp database.
"numbers" menu item will appear after that.
Click on "numbers" menu item to manage number table.
Now click on "Insert" tab at the top of page.
Fields number and prefix will appear.
Enter desired values and click "Go" to insert these values.
Done!
How to import numbers from CSV
There is no such option to import numbers from CSV in MOR GUI, but numbers can be imported directly to MNP database.
This procedure is described here:
1. You need to have CSV file on your server and file should look like:
... 37012312345;9991 37012312344;9991 37112312343;9992 37112354321;9992 ...
2. Open MySQL CLI:
mysql mor_mnp
3. Create temporary table and import CSV file to it:
CREATE TABLE temp (col_1 VARCHAR(50) default NULL , col_2 VARCHAR(20) default NULL);
LOAD DATA LOCAL INFILE '/home/mnpnumbers.csv' IGNORE INTO TABLE temp FIELDS TERMINATED BY ';' ;
4. Copy data from temporary table to 'numbers' table:
INSERT INTO numbers (number,prefix) SELECT REPLACE(col_1, '\r', ), REPLACE(col_2, '\r', ) FROM temp WHERE (REPLACE(col_1, '\r', ) REGEXP '^[0-9]+$' = 1) and (REPLACE(col_2, '\r', ) REGEXP '^[0-9]+$' = 1) ;
NOTE: this query skips values which contains non-numerical characters.
For example: row
... +370123123456;9997 ...
will not be imported to 'numbers' table.
5. Detele temporary table:
DROP TABLE temp;
Done. Numbers are imported to 'numbers' table.
How to configure external MNP database
Skip this step if your MOR billing installation is on one server.
Locate mor_mnp.conf file
cd /usr/local/mor
Edit the file with your favorite text editor, for example:
mcedit mor_mnp.conf
You should see similar values, mind the gaps in the file, they should be exactly the same as in the example below:
host = localhost db = mor_mnp user = mor secret = mor port = 3306 server_id = 1 show_sql = 0 debug = 1
Change the values to the ones you need:
host - your database IP address
server_id - your Asterisk server id, same as in /etc/asterisk/mor.conf
