TNG connects to Asterisk via the network to the Asterisk Manager Interface (AMI). The AMI normally runs on TCP port 5038 on the Asterisk machine.
Step 1: Enable the Asterisk Manager Interface
Step 2: Add a user for TNG
Step 3: Enable CDR on Asterisk
Step 4: Enable CDR via the AMI
Step 5: Force Asterisk to reload the configuration
Step 6: Configure TNG
Step 7: Check that TNG has connected successfully
Explanation of log entries
- Step 1: Enable the Asterisk Manager Interface
We first ensure that the AMI is enabled.
enabled = yes port = 5038 bindaddr = 0.0.0.0
You should not enable the AMI on a public IP address.
If you do, people on the Internet will be able to connect to
the AMI and may cause problems.
Block this TCP port with iptables (or other firewall software).
- Step 2: Add a user for TNG
The default Asterisk has a
manager_custom.conf file, which
is included from
/etc/asterisk/manager.conf. Usually, additional
users are configured in this file.
For example, if we want to use login “
tng”, password “
and TNG will connect from IP 192.168.0.4, this would be the
[tng] secret=tng deny=0.0.0.0/0.0.0.0 permit=192.168.0.4/255.255.255.255 read=system,command write=system,command
Historically we used these settings, but it caused High CPU Usage.
You can make the login and password anything you want,
as long as TNG is configured to use the same login and password.
- Step 3: Enable CDR on Asterisk
- Step 4: Enable CDR via the AMI
We do not recommend using this anymore. Rather use the CSV file import facility.
- Step 5: Force Asterisk to reload the configuration
Check whether the cdr_manager module is loaded…
root@asterisk:/etc/asterisk# asterisk -rx "show modules like cdr_manager" Module Description Use Count cdr_manager.so Asterisk Call Manager CDR Backend 01 modules loaded root@asterisk:/etc/asterisk#`
Please see the Asterisk documentation if you have a problem with this part.
If the module is there, configure your TNG with the login and password
you set in Step 2.
Force Asterisk to reload the configuration:
asterisk -rx "reload"
if changes were made to the Config files you can reload the services.
asterisk -rx "reload manager" asterisk -rx "reload cdr" asterisk -rx "reload cdr_manager"
TNG should now be able to connect to Asterisk.
- Step 6: Configure TNG
Make sure that TNG is installed.
Login on TNG using a web browser, and click on the
“General Settings” icon (a gear and spanner) on the
TNG will prompt for a “technical” password. Enter the
technical password and search on the screen for the
Asterisk Interface configuration.
Here you enter the IP address of the Asterisk server,
AMI port (default 5038), Login and password that you
configured in Step 2.
Click any of the “Apply Changes” buttons to save.
- Step 7: Check that TNG has connected successfully
Back on Asterisk, at the command-line, check that TNG has connected:
asterisk -rx "show manager connected" Username IP Address tng 192.168.0.5
If you don’t see this, check the TNG log file for
