The ever-changing business landscape has driven voice technology to evolve from the good ol’ analog landlines to powerful digital telephony.
Pre-VoIP, analog systems have supported businesses for decades. They’ve been reliable tools for inbound and outbound calls, and can also be used to transfer calls across extension lines. It has well-known functionalities like hold, mute, redial and speed dial, but not much else. It’s simple and easy to use, but has limited potential for expansion.
Meanwhile, modern telephony allows companies to add more-advanced features and capabilities, such as music on hold, VoIP integration, and alarm systems, which can be supported with modular add-on boards. Newer IP interface allows unified messaging features like voicemail delivery to email, fax delivery to email, voicemail transcription to SMS, click to dial, and a desktop client.
