Ok. Thanks for the hint.
But, what exactly is a "System() dialplan application"? Is it a kind of command that i can call in dial plan?
I will look for System() related to dial plans.
Thanks.

Assunto: Re: [asterisk-users] How to invoke a binary file from the dial plan?
| Quote: | Hi everyone.
I'm new with Asterisk and I have to create a dial plan that will
invoke a binary code. That is, asterisk will execute a program in
the same machine. How to do it?
Let me explain what I have to do:
In the project that I am currently working, there is smartphones,
SIP servers and doors/gates to be unlocked remotely. When the user
executes an application on his/her phone, it will presents a button
to unlock a remote gate or door.
By pressing such button, the application will send a SIP INVITE to
the SIP server (Asterisk). In this moment, a existing dial plan
should call an executable hosted in the current machine. In this
case I need to know how to program my extensions.conf to let
Asterisk invoke another software to me.
The another software is the one responsible for unlocking a gate or door.
So, how to codify my extensions.conf in order to make Asterisk
invoke another software?
Is another better way (idea) to implement my project using Asterisk
and SIP? If so, comment, please!
Any hint will be very helpful!

Look into the System() dialplan application. It will execute a command on the system for you. Be aware that it will execute it as the user your Asterisk instance is running as, so permissions can sometimes be a bit finicky to get correct. I do something similar to pop my gate open. It is using nc to make a connection to the device, but same general idea as what you are doing.

From the Asterisk CLI type:
core show application System
It will print out the syntax for the command. One of the easier dialplan applications.
exten => 1234,1,System(echo "This is a test" >> /var/log/asterisk/test.txt)
That line would use the Linux echo command to place the text "This is a test" into a file named test.txt located in the /var/log/asterisk directory. |
