Maybe because i'm a noob on telephony dev. but what's a "soft phone"...does that mean that the humans who receive the calls don't actually use traditional phones (like landlines or mobile phones), but rather via their web browsers?

Silly question: but if i didn't want my folks to use web browsers, and simply wanted to route a call to whomever is on call (and that person works remote, let's say), I wonder if possible to simply route the calls to that person's mobile phone?
