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 the system owner to check if the number belongs to another network and, if so, route it through different providers or bill it with a different price.
The current implementation allows saving numbers in a MySQL database on any server (not necessarily the local server).
Before each call, MOR MNP Addon checks the dialed number and, if it is found in the database, adds a prefix to it.
By prefixing MOR, you 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: MOR - LCR/Tariff change based on call prefix
Kolmisoft cannot create a unique database for all MNP services across all countries worldwide. MOR admin has to
manually enter numbers in the MNP database (process described below) in order for this solution to work. 'mor_mnp' database has
to contain only the necessary data (telephone numbers).
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. Depending on MOR version:
MOR X16 (or older)
Run the script, which will update Asterisk extlines to work with the MNP database:
/usr/src/mor/test/scripts/asterisk/mnp_cfgs.sh
MOR X17 (or later)
Starting from MOR X17, enable MNP in /etc/asterisk/mor.conf
mnp_enabled = 1 asterisk -rx "mor reload."
How to see if MNP works
Open Asterisk CLI. During the call, check the very first lines shown in the CLI. In about the 10th line, you should be able to see lines like that:
MOR X16 (or older)
-- Launched AGI Script /var/lib/asterisk/agi-bin/mor_mnp mor_mnp: mor_mnp: MOR MNP AGI script started. mor_mnp: Successfully connected to the database. mor_mnp: Extension: 37012312345 mor_mnp: New extension: 37012312345 mor_mnp: MOR MNP AGI script stopped. mor_mnp:
MOR X17 (or later)
In the call log, the following line should be visible:
[2023-01-17 15:32:03] NOTICE[10659][C-00000007]: app_mor_various.c:4088 _mor_log: Checking number 37012312345 in MNP database
Also, check the output of asterisk -rx "mor show status", you should see MNP status:
MNP enabled: 1, MNP active: 1
MNP enabled - shows if MOR core is aware of MNP existence.
MNP active - shows if MOR core successfully connected to MNP database.
If you cannot see it. Something is wrong with the 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 a 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 the correct MySQL permissions for the mor_mnp database, and that local or remote Asterisk has the 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 of 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 a number and a prefix.
To manage the mor_mnp database, you can use PhpMyAdmin:
http://<your server IP>/mordbadmin
PhpMyAdmin login details can be found in the file /root/phpMyAdminPassword
If after logging in to PhpMyAdmin, the MySQL login page will appear, use these details to log in 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 the "numbers" menu item to manage the number table.
Now, click on the "Insert" tab at the top of the page.
The field number and prefix will appear.
Enter desired values and click "Go" to insert these values.
Done!
Number localization
In situations when a number can be dialed in multiple ways, you can set mnp_prefixes variable in /usr/local/mor/mor_mnp.conf.
For example, if number 123456789 can be dialed with the following prefixes 00370123456789, 370123456789, 8123456789, then you can set mnp_prefixes variable with the following prefixes:
mnp_prefixes = 00370,370,8
Then you will be able to upload only a single number 123456789 into the MNP database, and this number will be matched when the client dials 00370123456789, 370123456789 or 8123456789.
MNP tags in SIP INVITE
MNP tags (npdi and rn) can be enabled by setting Enable MNP tags to yes in Provider configuration.
If MNP tags are enabled and MNP lookup was successful, then npdi and rn tags will be added to SIP INVITE:
INVITE sip:DST_NUMBER;npdi;rn=MNP_NUMBER@IP SIP/2.0
here:
- DST_NUMBER - localized destination number, for example, +370123456789
- MNP_NUMBER - localized destination number with MNP prefix, for example +370999123456789
If the number is not found in the MNP database, then only the npdi tag will be added to SIP INVITE:
INVITE sip:DST_NUMBER;npdi@IP SIP/2.0
here:
- DST_NUMBER - localized destination number, for example, +370123456
Note that only SIP INVITE requests will be modified. Other SIP headers (such as TO, FROM) are not affected by Enable MNP tags setting.
How to import numbers from CSV
There is no such option to import numbers from CSV in the MOR GUI, but numbers can be imported directly to the MNP database.
This procedure is described here:
1. You need to have a CSV file on your server, and the file should look like this:
... 37012312345;9991 37012312344;9991 37112312343;9992 37112354321;9992 ...
2. Open MySQL CLI:
mysql mor_mnp
3. Create a temporary table and import a CSV file into 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 the temporary table to 'numbers' table:
INSERT INTO numbers (number,prefix) SELECT TRIM(REPLACE(col_1, '\r', '')), TRIM(REPLACE(col_2, '\r', '')) FROM temp WHERE ( TRIM(REPLACE(col_1, '\r', '')) REGEXP '^[0-9]+$' = 1) and (TRIM(REPLACE(col_2, '\r', '')) REGEXP '^[0-9]+$' = 1) ;
NOTE: This query skips values that contain non-numeric characters.
For example row
... +370123123456;9997 ...
will not be imported to 'numbers' table.
5. Delete temporary table:
DROP TABLE temp;
Done. Numbers are imported to 'numbers' table.
Automatic import script
Script downloads compressed (ZIP) CSV with a list of numbers from the SFTP server and imports in with default prefix to the MNP database. Current ZIP file required. Only SFTP is supported. The script does not import prefixes from CSV. CSV should contain an only list of numbers.
The script is located in /usr/src/mor/sh_scripts/mnp_numbers_import.sh
Script uses the same configuration file /usr/local/mor/mor_mnp.conf. Options which are specific to this script:
download_url = sftp.server.com:/path/to/file.zip #some remote location of a number file (for sftp) username = ftpuser #user name to connect to a remote server password = ftppassword #password for a user to connect to a remote server default_prefix = 0009 #default prefix for numbers (current version does not support prefix import)
Note:
If you are using the MOR X18+ version on Rocky Linux 9 and an FTP server on an older operating system, then these errors can occur using the script:
Unable to negotiate with xxx.xxx.xxx.xxx port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss
ssh_dispatch_run_fatal: Connection to xxx.xxx.xxx.xxx port 22: error in libcrypto
The best way is to upgrade the FTP server to a new operating system. If you do not want to upgrade your FTP server, then you can use another option to run this command on the MOR Rocky Linux 9 server:
update-crypto-policies --set DEFAULT:SHA1
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 mnp_prefixes = 00370,370,8
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
How can I add a specific prefix on a call to the ported number?
It's possible to add a specific prefix to the call in this way:
- Create a duplicated provider (for example, you have "Provider A (no MNP) and "Provider A (with MNP)")
- Create Provider Rules for that provider by adding a prefix 060
- MOR will route numbers in the MNP database through that provider according to the Provider Rules.
