It's funny because that's what everyone points out lol. Yes! My dads hobby is VOIP phones and he runs a PBX all of us kids have a Voip phone and we do a lot of calls over them. It's also where my voicemails from my cellphone go lol
I've got 2 lines coming in and he has probably around 70 extensions for all his locations. When you call into the main line it asks you to type the first 3 letters of who your looking for then transfers to our extension he's also got a lot of ham radio stuff running through his PBX and even local radio station EXT
hahaaa thats awesome. i used to be a cisco phone guy myself (tho never one of the super smart guys) so ive known a few guys who get real into the home network thing
