Adding a SIP client to FreePBX

To add a SIP client to FreePBX, open the menu “Applications” – “Extensions“, choose for example “Generic CHAN SIP Device” and we indicate the main parameters:

User Extension: 6000 (SIP number)
Display Name: Operator (any name to display)
Secret: PASSWORD
and click “Submit“.

Done, SIP is added, it can already be registered at the specified number and password.

How to add SIP in the configuration file I described in this article – Adding SIP clients to Asterisk

Solving the error “insserv: warning: script ‘script’ missing LSB tags and overrides”

I noticed once the following error:

insserv: warning: script ‘MyScript.sh’ missing LSB tags and overrides

It appears because someone wrote the /etc/init.d/MyScript.sh script before writing the LSB tags first.

To fix this, I opened the script code in a text editor (in the editor nano Ctrl+X to exit, y/n to save or cancel changes):

sudo nano /etc/init.d/MyScript.sh

And added in the beginning:

### BEGIN INIT INFO
# Provides:          MyScript
# Required-Start:
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      1 0 6
# Short-Description: ...
# Description: ...
### END INIT INFO

Installing the Digium Asterisk GUI

Digium Asterisk GUI – web-management interface Asterisk.

Today I’ll sculpt it to Asterisk 11 on Ubuntu Server 14.04 LTS.
Switch directly to the root user:

sudo -i

Download it:

apt-get install subversion
mkdir -p ~/asterisk-gui
cd ~/asterisk-gui
svn checkout http://svn.digium.com/svn/asterisk-gui/branches/2.0/

We compile and install:

cd 2.0
./configure
make
make install

Just in case, we’ll make a copy of the Asterisk configuration files:

cp -r /etc/asterisk /etc/asterisk.original

Open the configuration file manager.conf for example in the editor nano (Ctrl+X to exit the editor, y/n to save or cancel changes):

nano /etc/asterisk/manager.conf

The main parameters that must be configured in the manager.conf configuration file are:

[general]
enabled = yes
webenabled = yes
bindaddr = 0.0.0.0
[USERNAME]
secret = PASSWORD
read = system,call,log,verbose,command,agent,user,config
write = system,call,log,verbose,command,agent,user,config

At the very end of the file, replace the symbol # with; otherwise you can not enter under the login and password specified above.

Now edit http.conf:

nano /etc/asterisk/http.conf

In it we will specify the following parameters of the web server:

enabled=yes
enablestatic=yes
bindaddr=0.0.0.0
prefix=asterisk

Let’s check the settings:

make checkconfig

Delete the empty folder and specify a link to the real one with the files of the web server:

rmdir /usr/share/asterisk/static-http/
ln -s /var/lib/asterisk/static-http/ /usr/share/asterisk/

Restarting Asterisk:

/etc/init.d/asterisk restart

Now Digium Asterisk GUI should open by link http://192.168.56.102:8088/asterisk/static/config/index.html, where 192.168.56.102 this is the IP or Server domain with Asterisk.

To log in, we’ll specify the username and password you wrote earlier in the manager.conf file

Done.

Asterisk Error Solution “Context ‘local’ tries to include nonexistent context ‘parkedcalls'”

I screwed the DAHDI board somehow and noticed the following error when I dialed the call from the analog line:

WARNING[7238]: pbx.c:12314 ast_context_verify_includes: Context ‘local’ tries to include nonexistent context ‘parkedcalls’

The error occurred because the res_parking module was not loaded to load it, open the asterisk console and execute the command:

sudo asterisk -vvr
module load res_parking

To automatically load it when starting Asterisk, in the file /etc/asterisk/modules.conf, in the [modules] block, add the line:

load => res_parking.so
