New member here. Sorry if these questions has already been asked, but did a little searching the forums and nothing stood out.
I am trying to get a better understanding of what Asterisk can actually do. Can Asterisk do the same thing as Ringcentral.com or Grasshopper.com, where it assigns a phone number and I can setup extensions and users and an automated receptionist where it states press 1 for… press 2 for… press 3 for… and have voice mail boxes for each seperate extension, a main greeting message, transfer message, and voice mail message?
Also how is a phone number establish or assigned to Asterisk, how do you get the incoming calls to come to Asterisk?
