business telephone systems

A business telephone system is a multi-line phone system used in a professional environment. For enterprises and small businesses alike, this has grown to include more advanced features for managing phone calls and modern communications solutions. More specifically, IP (internet protocol) technology has expanded the possibilities of phone systems. This includes integration with other business software.

In its early forms, business telephone systems used technology such as the key telephone system. More recently, this has evolved to cloud-based private branch exchanges
However, business telephone systems have evolved. One of the first advances allowed users to connect to other desk phones without depending on an operator or switchboard. PBX systems now connect modern SIP (session initiation protocol) and IP phones. These are also known as VoIP systems. Users can also access their office phone extension over the internet or via a mobile app.
