Searching for an app to Send & Recieve recording audio in emergency situtations I tried to complete this task, using tasker and automate but didn't sucess.

I didn't found a way to send the audio message, to the second android in realtime (like whatsapp, or pushbullet).  

I want to make a task that record 5 seconds, and send it to another android.
I want it, for my wife, so he can send me emergency alert, if something happen, and she needs me.

The another android (my android), will play the file.
I want it to always work. If the receiver is in a middle of a call, it will hangup and play the sound fil
.
The question: 


How to record 5 seconds? 
How to send it? 
How to play it on the receiver?


You dont need to give me full answer, any help, and ways to solve it will be appreciate.

Thank's.
I tried many many things.

In the end... I success using sending simple MMS message.

Then I create a task, that on receive MMS, it will emulate touch events, for play the file (I run the messageing app, and click on the last message to play it)
