Before hosted phone systems (the bad old days)
Not so long ago, if a business wanted to operate multiple phone lines in their office, they
needed a special piece of equipment called a PBX (short for private branch exchange). A PBX
phone system provides the technical ‘smarts’ to deliver multiple calls at the same time. It
also allows those calls to be handled through manual features (like call transfer) or
automated features (such as a mobile diversion or hunt group).
But, traditionally, this powerful technology has come with significant challenges.
