[asterisk-users] prevent invalid queue members

[hwilmer]

Hi,

when using AddQueueMember() to add to a queue, it is possible to add
unreachable (non-existing) peers to a queue.  Such members show up
marked as '... (dynamic) (Invalid) ...' when using the queue show
command.

Is there a way to disallow adding unreachable peers to a queue?
"Unreachable", in this case, means peers that can not be called
like because they aren't registered or because they do not
exist.

If not, is there a good way to automatically remove invalid queue
members?
