asterisk users - Jun 2015 - RES: How to invoke a binary file from the dial plan?

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!

Best regards.

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.

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.
