[App_rpt-users] Console Operation

I have been having the very same thoughts for quite a while.  I am an old
dispatcher from way back and tend to still think this way.  There are a
number of IP Dispatch Consoles on the commercial market today.  This enables
1-n people to access a 1-n radio channels across an IP bearer.  There are
many added functions that would enable cross patching of channels and other
neat features.  Having this functionality as part of our solution would
enable many very interesting use cases.   Here is what I would do in my
community with this functionality:

1.  I have an Emergency Operations Center (EOC) in a valley with several
multi-channel Remote Bases 2500 feet above on a tall mountain.  They are
currently controlled via link radios and DTMF.  If I add these to Asterisk
then I can have full control via IP from the EOC or the mobile EOC.  I need
simultaneous access to these channels.

2.  in the same area we have a very large Search and Rescue Community that
has in-town resources that coordinate resourcing for the field across
several different radio channels.  If i add these to Asterisk then those
in-town resources can monitor the field operations and communicate across
several different radio channels.

3.  I would like to take the new developments for voting receivers and place
these through out the area to listen for 121.5 ELT, EPIRB and PLB signals in
areas that we have routine turnoffs like small airports and fishing boat
terminals.  A dispatch console application gives me immediate access to many
receivers so that I can instantly know which channel.  I would also use this
to monitor the various channels in a voting system to determine location....

4.  An EOC  is typically in the basement with the radios on the roof.  A
cheap dispatch console cleans ups the EOC from an appearance and operational
perspective and allows the radios to be in another room, on the roof or on a
mountain top.

5.  We create a mutli-channel network that runs all the way around Mount
Rainer each July for a ugly bike event (10,000 of elevation gain).  This is
on a 4 channel network with two net control operators.  This means I need 8
radios in base camp to support the event.  I can reduce this to 4 with a
proper dispatch application and app-rpt.

The current application handles 1 channel.  In my use cases I typically need
2-5 channels.  You can buy this type of solution all day long for tens of
thousands of dollars from commercial vendors.  These are all low budget
volunteer run operations so funding is paramount.  Most of this is
Commercial so All-Star is not an option for linking.
