When they say voice is networking...

They’re lying, coping and/or insane.
Unless you like playing telephone... and want to learn knowledge that Cthulhu might smile at, then walk away.

if you are mr network rain man go for it, but realize the responsibilities and knowledge load you are throwing on yourself. I think there‘s a reason why the route and switch fellows don’t touch it. Be like them.... until you’re ready.

maybe being half serious...
