VoIP, or Voice over Internet Protocol, is a type of IP technology that takes analog audio signals and turns them into digital data that can be transmitted over the Internet. In other words, it uses standard Internet connection to provide communication services for a fraction of the cost of traditional telephone systems.By using a VoIP device (also known as softphone), you can make calls to other devices using the same technology, including mobile phones or landlines in general.

The most common features include: Call Transfers; Call Waiting, Call Identificator, Schedule access, Multiple accounts or lines, Call Park, Video and Audio Transmission.

Nowadays, more and more businesses are migrating from traditional copper-wire telephone systems to VoIP systems – in fact, 80% of all new Private Branch Exchange (PBX) lines installed internationally since 2008 have been VoIP. Here are some of the reasons why companies switch to this technology for corporate communications:

• Low infrastructure costs: because VoIP makes it possible that both data and voice communications run over a single network, infrastructure costs are significantly reduced in comparison with traditional systems.
• Bandwidth efficiency: the performance of this technology depends on the bandwidth of your Internet connection, meaning that a fast connection can support numerous lines. For example, a bandwidth of 30 Mbps can support more than 70 lines.
• Unified communication: many businesses use VoIP Telephony because it allows them to unify various communication services, including phone calls, faxes, voice mail, e-mail, and even video conferences.
• Low extension prices: the prices for integrating extensions on VoIP devices are significantly lower than PBX and key systems – in fact, they rely on standard interfaces instead on closed architectures.
• Easy to use – this technology can usually be accessed through a simple and intuitive interface that allows users to make simple system configuration changes easily. In fact, dual-mode phones remove the need to carry both a desktop and a cell phone, making it easy for users to continue their calls as they move between an outside service and an internal Wi-Fi network. This functionality also reduces maintenance costs.
• Call recording: VoIP technology makes the recording of calls and other types of office interactions easier and more efficient because it allows companies to integrate different communication services into one single device or software.

New technology telephony systems benefit businesses by providing better internal communications, general notifications and emergency alerts. Both analog and IP paging solutions are available. The versatility of devices like door phones, entry phones and intercoms makes them ideal for any kind of communications and security strategy.

In retail spaces, paging speakers serve as dual-purpose solutions for both announcements and background music. Offices and warehouses can pair entry phones and door controllers with locking mechanisms to create keyless entry and intercom systems. Purpose-built devices like emergency phones are also available.

Multiple communication networks exist as entirely separate entities, each serving a specific application. The traditional public switched telephone network (PSTN) time-division multiplexing (TDM) network serves the voice application; the Internet and intranets serve data communications.
