This guide will explain how to replace Flash Operator Panel v1
, which is included in FreePBX, with Flash Operator Panel v2
 on a RedHat Enterprise Linux server running Asterisk+FreePBX.  It is important to note that FOP1 is completely free whereas FOP2 is free only up to 15 buttons.  Every element is considered a button.  So all extensions + trunks + queues + parking lots + etc. must add up to 15 or less.  After that no more buttons will appear until you buy a license.

A key advantage of FOP2 is that it requires an extension and password to view.  With FOP1 there is no built in way to prevent everyone from viewing the PBX status.

Command line text is in .

For this procedure we assume you are using:

Redhat Enterprise Linux v5+ (or one of the free generic versions)

FreePBX v2.9+

Flash Operator Panel 2.20+

First install Linux+Asterisk+FreePBX


 

From a console on your FreePBX server (assuming i386 for the rest of this procedure):

cd /usr/src

tar zxvf fop2-2.20-centos5-i386.tgz

cd fop2

make install

This will copy the files to /usr/local/fop2 and the web pages to /var/www/html/fop2

cd /usr/local/fop2

cat extensions_override_freepbx.conf >>/etc/asterisk/extensions_override_freepbx.conf

This appends the contents of the fop2 version to the existing contents in the asterisk version of this file.  In many cases the asterisk version will be empty but we do it this way just in case it’s not.

For Deny use: 0.0.0.0/0.0.0.0

For Permit use: 127.0.0.1/255.255.255.0

With /etc/asterisk/manager_additional.conf

This is the new manager api we created above via the Asterisk API
FreePBX module.  In this case we gave it a manager name of fop2
and a manager secret of fop2secret.

secret = fop2secret

REPLACING FOP1 LINKS WITH FOP2

Copy the FOP2 index.html file to index_amp.php which FreePBX expects to find.

cp /var/www/html/fop2/index.html /var/www/html/fop2/index_amp.php

Change ownership

chown -R asterisk.asterisk /var/www/html/fop2

Now reload apache in order for the changes to take effect.

service httpd restart

 After installing the module go to the Asterisk SIP settings menu (Tools>Asterisk SIP Settings).

At the bottom set Call Events = Yes




Alternatively if you don’t want to install the Asterisk SIP settings module you can add callevents=yes
to /etc/asterisk/sip_general_custom.conf.

You will have to choose a queue number and name at the very top as well.   123
for example.

TEST MANAGER CONNECTION

You should see «Connection to manager OK!»  If you did not set queue as above you will get an error regarding that which is ok as long as you don’t plan to use queues.

CHANGE FOP1 PORT #

FOP v1 is included with FreePBX.  Before starting FOP2 we need to change the port # of FOP1 to something other than port 4445.  This is because FOP2 also uses 4445 by default.

Alternatively you can prevent FOP1 from starting.  This would normally be preferrable however it causes a constant «WARNING» indicator on the FreePBX dashboard.  Therefore it is not the recommended approach.  If however you prefer to do it this way, in FreePBX v2.9 we do this using the new Advanced Settings Menu (Tools>Advanced Settings).

Find the Flash Operator Panel Section and set S tart FOP with amportal
 to  FALSE
.

Make sure you restart amportal or reboot to ensure FOP1 is running on the new port. 

ENABLE FOP2 on BOOT and START

chkconfig fop2 on

service fop2 start

SERVER STATUS PATCH

On the FreePBX dashboard (FreePBX System Status) there is a server status on the bottom right that will show Op Panel > in yellow if you stopped FOP1.  If you did not stop it then it is showing the status of FOP1 not FOP2.  In order to correct this we need to patch FreePBX.  NOTE1: future updates to FreePBX may reverse this patch which would require this procedure to be repeated. N OTE2: This fix only works with FOP1 configured to start with FreePBX.  This is because FreePBX first checks if FOP1 is configured to start before checking the listen port.

This patch assumes we have FOP2 set to the default listen port 4445.

First create the patch file:

— class.procinfo.php  2011-01-06 12:54:05.000000000 -0500

+++ class.procinfo.php.new      2011-01-06 12:47:55.000000000 -0500

       $listen_port = 4445;

+     $listen_port = 4445;

Apply the patch:

patch < /usr/src/fop2patch.diff

Once again, this patch only works if FOP1 is configured to start with FreePBX as explained further up in this document.  If FOP1 is configured to not start, FreePBX automatically assumes FOP1 is not running, will not run our patch to listen to FOP2 on port 4445, and will always show a warning on the dashboard.

Обновление модулей FreePBX13 через CLI (консоль)

Работает с Asterisk через консоль

1 минута чтения

Привычный и удобный интерфейс FreePBX удобен для обновления модулей Asterisk – к нему мы уже привыкли. Но не многие знают, как обновить модули через командную строку (консоль, CLI). Разберемся сначала, как обновить конкретный модуль, а затем, как обновить все модули сразу.

Разберем обновление модуля framework. Для этого, через любой SSH клиент подключитесь к вашему Asterisk через CLI и зайдите под правами root

Далее, вводим следующую команду:

После успешной установки, нам необходимо применить настройки. Как помните, в FreePBX есть красная кнопка «Apply Config». Ее аналог через CLI это следующая команда:

На этом модуль Framework обновлен. Давайте теперь рассмотрим процесс массового обновления всех модулей
сразу. Для этого, введем следующую команду:

После ввода данной команды, Asterisk начнет обновление всех модулей, для которых доступен апгрейд. По окончанию обновления, аналогично применим конфигурацию командой:

Пожалуйста, расскажите почему?

Нам жаль, что статья не была полезна для вас 🙁 Пожалуйста, если не затруднит, укажите по какой причине? Мы будем очень благодарны за подробный ответ. Спасибо, что помогаете нам стать лучше!

Then click Apply Config

the fact is that I opened the logs with superuser rights, correcting this matter:

After I press Retry
but the problem does not disappear, so I do this:

That’s how the problem was solved.
