Installing MiRTA PBX is not a piece of cake and the automatic installer has been proven only on CentOS 6 64bit. Even with the automatic installer, a series of manual steps are required.

Installation steps

  • Copy the installer script from pbx/protected/installMirtaPBX.sh to /usr/local/src in your new server. If you need you can recover this file from

http://demo.mirtapbx.com/mirtapbx_support/installMirtaPBX.sh

  • Move to /usr/local/src
  • Edit it and check the version, set to 6
  • Check your hostname, change to something more useful if you have set to localhost
  • Upgrade the Kernel by running
./installMirtaPBX.sh Kernel
  • Reboot the server to be sure to have the latest kernel running
  • Move again to /usr/local/src
  • Install the system by running
./installMirtaPBX.sh

If there will be no errors, you'll have asterisk and voipmonitor compiled and installed.

Proceed in checking if SELinux is active and disable it 

# getenforce
Enforcing
# setenforce 0
# getenforce
Permissive

Move in /var/www/html/pbx and start by configuring include/db.inc.php copying from include/db.inc.php.sample 

# cd /var/www/html/pbx
# cp include/db.inc.php.sample include/db.inc.php

Edit the include/db.inc.php and fill in with the mtpbxname and mtpbxkey values provided

Upgrade the database to the basic version: 

# php dodbupgrade.php

There will be some errors and notice, just ignore them. Now convert the database to UTF8. 

# cd protected
# php convert_to_utf8.php

Now it is time to setup the timezone on php. Try running the checkupgrade.php utility 

# cd /var/www/html/pbx
# php checkupgrade.php

If you see an error like: 

PHP Warning:  strtotime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /var/www/html/pbx/checkupgrade.php on line 19

It means you need to carefully select the timezone in php.ini, like 

[Date]
; Defines the default timezone used by the date functions                                                                                                                                                        
; http://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone                                                                                                                                      
date.timezone = Australia/Sydney

Now move to /etc/asterisk and edit sip.conf and manager.conf setting up the entry for the server itself, replacing srv01 with your server short name 

[IC-PBX01]
context=fromotherpbx
type=friend
defaultuser=IC-PBX01
secret=j47fgh3d56g238rk20s
host=192.168.80.50
qualify=yes
insecure=port,invite

If the server is on private IP, then you need to identify the public IP and add in the [general] section: 

externip=103.161.91.22
localnet=192.168.80.0/24

Once set sip.conf, proceed in reloading and verify if the server itself is reachable 

# asterisk -rx 'sip reload'
# asterisk -rx 'sip show peers'
Name/username             Host                                    Dyn Forcerport Comedia    ACL Port     Status      Description                      Realtime
IC-PBX01/IC-PBX01         192.168.80.50                               Auto (No)  No             5060     OK (1 ms)

Add the local IP address to manager.conf 

[manager]
secret=jkfu57fh3d7nms2
deny=0.0.0.0/0.0.0.0
permit=127.0.0.1/255.255.255.255
permit=192.168.80.50/255.255.255.255
read=system,call,log,verbose,agent,user,config,dtmf,reporting,cdr,dialplan
write=system,call,agent,user,config,command,reporting,originate

Reload the manager interface 

# asterisk -rx 'manager reload'

Now move to /var/lib/asterisk/agi-bin and apply the same configuration change about include/db.inc.php

Edit devstate.conf.php (copying from devstate.conf.php.sample) and list the IP address for the servers belonging to the cluster 

$server=array('192.168.80.50');

Proceed on the web interface and login using admin/nabucco347 credentials.

Fill the Admin/Settings page with the International Prefix, Trunk Prefix, License Key, Voipmedia retention and Call History days. I suggest also to select the Show Status of Extensions, Admins see all tenants and choose at least a format for DID selection.

Save the configuration.

Press on the Upgrade button to upgrade top latest version.

Log out from the web interface and log in again to apply the database upgrade.

Move to Admin/PBX Nodes and Add a new node. The most important one is the Peer Name. It needs to match the "uname -n" from the OS.

Change Admin password and reboot the server.

Start configuring your system.

Clustering systems

If you want to create a cluster with 2 or more MiRTA PBX Asterisk servers, there are just few additional steps:

  • In sip.conf and manager.conf, you need to enter the configuration for all nodes. Sip.conf and manager.conf are exactly the same for each server (except if you use externip, in this case, you have to place the right IP in each sip.conf)
  • Double check the sipregs view that has been created when adding nodes in Admin/Nodes. If you server peername is "pbx01", then you should have a sipregs_pbx01. In extconfig.conf enable the sipregs entry and enter the view name of the server you are configuring. You need to enter the same sipres_<peername> on both rows.
  • Enable sipregs usage in /var/www/html/pbx/include/db.inc.php and in /var/lib/asterisk/agi-bin/include/db.inc.php by setting 
    $usesipregs="yes";
    Please note your directories can be slightly different based on the OS you are using.
  • Enter all your server's IP in /var/lib/asterisk/agi-bin/devstate.conf.php
  • Please note all nodes need to share a common database. This can be accomplished using a central MySQL database server (discouraged) or a series of MySQL databases doing multi master replication (advised)

Additional Daemons

Normal install will configure the auto start of three daemons:

  • devstatesender
  • devstatereceiver
  • panelserver

You may want to run additional daemons for specific purpose:

Multimanager

It allows users to connect to asterisk using a restricted AMI. You can create users in Configuration/Settings/Manager Users. This restricted AMI process is listening to port 5039 

nohup /usr/local/bin/restartmultimanager.sh &

Realtime Portal

A websocket application showing a panel with all extensions, parking lots, queues and more to allow management of the calls.

For now it is in its early stage of development, but you can check it running (PHP 5.5 required) 

cd /var/www/html/pbx/rtportal
php server/bin/server.php

Don't forget to configure Apache for websocket SSL if you want to use it Configuring_apache_for_Web_Socket_SSL_Realtime_Portal
