VoIP (Voice over Internet Protocol), a technology that allows businesses to cut down on their communications costs, can prove to be a great option for both small and large companies. 

Voice over IP (VoIP), phone systems function in the same manner as for regular public switched telephone networks (PSTN), except that the internet is used to transmit signal information.

Hosted VoIP PBX systems offer many of the same services as regular phones, such as voicemail, caller ID, and conferencing at much lower costs. Voice over Internet Protocol phone systems combines voice and data transmissions within one system.

This means that telephone communication and digital data transfer can be done virtually simultaneously using the same medium with minimal cost.

These IP telephony systems allow companies to connect all of their global offices and save significant amounts on long-distance calls to remote offices.

Voice over IP (VoIP), phone systems for companies can be set up with existing computers using headsets and telephone dialer software. The headset can act as a handset for your office phone, and the dialer software emulates the functions of an IP Phone system. 

This arrangement is great for business travelers as it allows them to convert their laptops into an Internet protocol phone system that can be used to communicate with clients no matter where they are located. Only one requirement is that you have an internet connection to allow communication to occur.
