DialPlan For DVSwitch Tune

This is a example asterisk/app_rpt dialplan for tuning the DVSwitch MMDVM system. Please note that there is no perfect way to tune dvs in all modes with dtmf... YET ! This is a workaround.

We make use of a modified autopatch entry. Please read this page before you start. / How To Pass DTMF To Shell Scripts

Assuming you have created the special autopatch context dialer command as described in that page and given it a unique context to dial into, that we will use here as

[dvs-set] ; this context needs to be unique in the system & match your dialing context.

Use Format:

(AP command prefix) + (dvs mode 1-5) + (dvs tg)

Requires that you set dvs mode each time with the leading digit 1-5.

So, a command here of *97 1 3100 would set dmr 3100

And *97 2*2xxx would tune dstar dcsxxx

2xxxx tunes dstar adhoc number only

2*1xxx tunes dstar REFxxx

2*2xxx tunes dstar DCSxxx

2*3xxx tunes dstar XLSxxx

2*4xxx tunes dstar XRFxxx

2*5x tunes dstar mem # or ## from file

3xxxxx tunes YSF xxxxx

4xxxxx tunes P25 xxxxx

5xxxxx tunes NXDN xxxxx

** disconnects from any mode

DStar Memory File

The intention here was just a method to connect systems that can not be entered into a 15 usable dtmf digit string reasonably. But you could just store your favorite 10 for ease of dialing.

To use dstar memory calls, you need to create a file in /opt/MMDVM_Bridge/dstar.mem

and populate it one dstar connection of any valid call that can be made through DVS per line

Do not put anything else in the file as it begins reading from line 1 (no comments or blank lines)

A extra command in the dialplan of " 2*5 xx " will call the line# of the memory file.

EXAMPLE

dcs006f

DCSSAT

DCSUS1

DCSUS2

DCSUS4

Requires one additional batch file in the /opt/mmdvm_bridge/ directory called dstarmem.sh with these contents

1. !/bin/bash

/opt/MMDVM_Bridge/dvswitch.sh tune $(sed "$1q;d" /opt/MMDVM_Bridge/dstar.mem)

(for some reason I could not execute this inside the dialplan and suspect it's our older version of asterisk or some bad syntax... so, using alt method)

Don't forget to set ownership and permissions of the dstarmem.sh file

Summary

While this is not a perfect model of operation, it is a functional example for which allows you to develop your own methods beyond it using methods and principles you see.

The intention here was the old KISS rule and to keep it all in one place as much as possible for easy understanding. Obviously, this will challenge your memory if you do not use it often.

For those of you who require such functionality, make a cheat sheet to carry with you mobile/portable etc.

Perhaps you will devise something better we can post here ?

Since we are dialing by context, and to keep my extensions.conf file a bit cleaner (it's big),

I set this in a file in /etc/asterisk/custom named dvs.conf and call it at the end of extensions.conf

'#includeifexists custom/dvs.conf' .
