Asterisk Tip:
Not in the mood to compile and install Asterisk 13 from source-code ?
Use YUM(DNF) then :

The latest changes in Fedora/Centos has changed YUM to DNF :
Simply run this command from command line with a working internet connection :

dnf -y install asterisk asterisk-devel asterisk-voicemail asterisk-fax asterisk-voicemail asterisk-sounds-core-en asterisk-odbc asterisk-sqlite asterisk-oss asterisk-iax2 asterisk-sip

chmod's :
===========================================================

To get astdb to work run :
chmod 666 /var/spool/asterisk/astdb.sqlite3

Sounds:
===========================================================
Stored in /usr/share/asterisk/sounds/

An example of what you get in our Electronics course.  Each student
gets their own box of components.

We want to give a huge thanks to the students that attended our first Electronics course. We thank you for your support and comments about the course.
We think it was a success and we look forward to the next course on the
10th of October.
This photo shows how easy it was to connect up the components using the solderless breadboard.

Gate access using Atmega328, MT8870 DTMF chip and GSM to analogue phone line.
The device calls the programmed number when one of the buttons are pressed. The unit then acts as a speaker phone to talk to the owner of a townhouse. The owner press a key on his/her mobile phone to open the gate. I need to finish the amplifier still - going to be LM386 based with 600ohm 1:1 transformer.

Please let me know if you've come across one of these in your country or have any ideas to improve it
