[arm-allstar] scripting - last dtmf digit received in client display

[David McGough]

Hi Doug,

I agree that moving various operations out of the app_rpt code entirely
and to the dialplan (perhaps including AGI scripts) is the ideal approach,
since Asterisk already has sophisticated DTMF matching and scripting
capability, etc...While I'll not privy to the history of why it was
originally coded this way, I'll speculate that probably it was partly due
to functionality limitations found in early versions of Asterisk, years
ago.

A question I've got with the method of using the autopatch functions to
reach the dialplan is whether there are any hidden side effects--I haven't
looked thru app_rpt.c carefully in that regard--YET.  While I'm not
wanting to add even more code to app_rpt.c, this is one area where we
might need to add some code to improve integration with dialplan
functionality?? (thoughts?)

As you know, I'm a proponent of lean, focused, highly modularized code.
Going along with that premise, IMO, the remote-base support code should be
completely stripped from the app_rpt.so module and migrated to another 
format--probably not even being a 'C' program, but, rather a higher-level 
scripting language. And, for the actual radio-control operations, use 
hamlib, which is what I'm already doing on my custom version.

Anyhow, lots to ponder! I'm not going to get bogged down on this just now.

but basically the way this is setup if you enter at the radio  *611xxxxx  
the last 5 digits will be passed as the EXTEN variable in Asterisk. At 
that point you could do whatever you wanted with it - like pass to a 
script that sent it to hamlib for execution. Of course the number of 
digits could be changed and other functions could be added.
