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

[Rodrigo Pimenta Carvalho]

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.

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.
