Hi Kevin.

Thank you very much for the hint! It worked very well!

Your example ' exten => 1234,1,System(echo "This is a test" >> /var/log/asterisk/test.txt) ' executes when the SIP client (my softphone Jitsi) sends a SIP INVITE to asterisk. So, the softphone tries to establish a session with target 1234.

Now, lets suppose my softphone rings and I answer a call. During the call, the caller asks me to execute a command (ex: to open a door or gate). In this case, what have I to program in dial plan to Asterisk execute System() again? Is it possible to execute a dial plan even during an ongoing call?

Finally, lets suppose I want to use my softphone to execute a dial plan, even without establishing a call (no session with target 1234). For example, If I decide to open a dor or gate using my softphone, without existing an ongoing call, what have I to program in dial plan to Asterisk executes System(). Is this idea possible?

Any hint will be very hepful!

Best regards.

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.

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.

I love this question, simply because it allows me to talk about one of the neatest features I programmed into my system that barely anyone knows exists. Plus it lines up pretty much exactly with what you are trying to do.

We have our gate control system tied into our Asterisk phone system so it is possible to dial a code on the phone and open the entrance gate to let someone in after hours. Only problem is this happens so rarely that no one (myself included) ever remembered the code. Thus a search for a better way.

Now, when someone uses the gate phone to request entry, I change the caller ID on the display of the person who answers to read "Press 9 to open gate". During the call, they can hit 9 at any time and the gate will open for them. Up until they answer, the caller ID reads Gate Phone, but when they answer, it changes to that text.

The part about opening the gate is the magic piece you want to look into. Read up on applicationmap in features.conf. It's pretty simple and very effective. Here is what mine looks like. I am going to replace my actual command with <insert command here>.

gate => 9,self/callee,System,<insert command here> ; Custom application to open the gate.

This says that this feature is active in the 'gate' context of my dialplan. The dialing pattern it is looking for is a 9. 'self' tells it to activate on the channel that dialed it and callee says that the person receiving the call is the only one that can activate it (otherwise the person at the gate phone could hit 9 to open it). I am running the System dialplan application and passing it the <insert command here> value. Everything after the ';' is a comment as normal. The <insert command here> is equivalent to what you would put inside the '()' if it were in the dialplan (i.e. 'System(<insert command here>)').

Pretty straightforward to get it working once you know what to look for. Let me know if you want to know how I manipulate the Caller ID upon answering the call to give the instructions to the callee on how to open the gate/door.

I just realized I said one piece wrong in this. 'gate' is not the context, it is the dynamic feature designator. I can illustrate this better by posting my front gate context.

[front_gate]
exten => <number gate dials goes here>,1,Set(__DYNAMIC_FEATURES=gate)
same => n,Goto(frontgate_queue,${EXTEN},1)
