Answer 1

Command: core show channel YOUR_CHANNEL

Answer 2

If you expect do events, correct way is use event. I.e collect NewChannel events and build map(for example, in memcached).

Running too many commands sometimes result problem with ami connection.

As an example of such code you can check FOP opensource or FOP2 project(no source now). https://www.fop2.com/about.php
