I think I've come up with a pretty simple solution.

Recording is simple. Just add "archivedir=/home/somefolder" to rpt.conf .

The problem was how to start and stop recording. Once you have set an archive directory in rpt.conf it just keeps recording their forever which is not what I needed.

My solution was to set the immutable attribute for the archive directory (chattr +i /home/allstarudio/*). This prevents any files from being modified or created in the archive directory. App.rpt is still trying to put files in the folder but it cannot.

So I made a simple script that removes the immutable attribute from the archive directory, sleeps for 15seconds and then adds the immutable attribute back. This allows any transmission made within that 15 seconds to be saved in the archive directory.

I then defined a custom DTMF function in the function stanza of rpt.conf. When this DTMF tone is dialed the mailbox.sh script will run and any transmission the user starts within the next 15 seconds will be recorded.

Script is copied below.

Anyone is welcome to dial my node and leave a message. Node # 49245






mailbox.sh

#!/bin/bash

# How to use this script

# You must Uncommnet or add the line "archivedir = /home/allstaraudio" in /etc/asterisk/rpt.conf
# You must also create the "allstaraudio" directory in your home folder
# create a custom DTMF macro in functions stanza of rpt.conf that calls this script.
# example dtmf macro "85=cmd,/home/yourusername/mailbox.sh"


#this sets the app.rpt audio archive directory to immutable
chattr -i /home/allstaraudio/*

# this pauses the script for 15 seconds. Any transmission that begins within this 15 seconds will be recorded even if it is longer than 15 seconds.
sleep 15s

#this adds the immutable attribute from the app.rpt audio archive directory preventing any further audio files from being stored.
chattr +i /home/allstaraudio/*

None. It's a hardware problem.

My goal is to create a simple 'answering machine' for my allstar node.

I would like for a user to be able to connect to my node and enter a DTMF command that would then cause the node to record the very next transmission and store it to a folder on a mounted volume on the PI.

I have looked into using the built-in recording feature via 'archivedir' . Howver I am not sure how to control it so that it will start and stop recording.

So my question is this. Is there a simple way to tell the node to record the next transmission, save it, and then stop recording? 

I am hoping this could be done via a script which could be called by app rpt via a dtmf command.

Any info or suggestions would be greatly appreciated.
