What is the current development of the VoIP in the office?

With VoIP, telephony signals are digitized and transmitted as packets to their destination, just as with an email, streaming video or any other kind of IP transaction. Today, VoIP comes in many forms, and some closely resemble traditional phone service from the point of view of the end user. Among numerous other benefits, the service allows five-digit dialing between offices in different locations around the country, thereby eliminating long-distance calls between branches. VoIP providers are introducing new price points and innovations such as area code mobility, real-time billing and service provisioning, and easy conference calling.
