You wont see it unless you run into problems or use noop in your dial
plan to show you what is being done.

But by design setgroup just sets a variable for the current channel,
it's the same as using SetVar(GROUP=whatever), as soon as issue
setgroup again the first group is gone, consider the following:
exten _.,1,SetGroup(test)
exten _.,2,SetGroup(test2)
exten _.,3,GetGroupCount(test)
exten _.,4,Noop(${GROUPCOUNT})
exten _.,5,GetGroupCount(test2)
exten _.,6,Noop(${GROUPCOUNT})

line 4 above will return 0, and line 6 will return 1. The reason is
because you have overwritten the variable ${GROUP} at line 2.

To Ronald, I think your problem has to do with the fact that you are
using local channels, which are then mapped to sip channels, but I
don't think you should have any operational problems, correct me if
I'm wrong.
