As the IP PBX market has evolved in the past ten years, it has grown to include more ‘virtual’, ‘internet-based’, and ‘in the cloud’ solutions. IP PBX support infrastructure has become increasingly reliable and hosted options have become a real option. Today, more than ever before, end users are able to choose the exact features and services they want at an afforded price.
A PBX (private branch exchange) is a telephone system within an enterprise that switches calls between enterprise users on local lines while allowing all users to share a certain number of external phone lines. The main purpose of a PBX is to save the cost of requiring a line for each user to the telephone company's central office.
