Description of VoIP - Voice over Internet Protocol is a technology that enables telephone calls to be made over computer networks like the Internet. VoIP converts analogue voice signals into digital data packets and supports real-time, two-way transmission of conversations using Internet Protocol (IP).
Phone calls can be made over the Internet - Instead of traditional phone lines, which typically cost more money. The cable companies are a prime example of using the Internet for carrying call traffic. Keep in mind all premise-based phone systems, without any additional hardware will accommodate the VoIP connections from the cable service. It is the responsibility of the cable company to provide the hardware.
Accommodating for multiple offices spread out over a geographical area - Can connect all their on premise phone systems via a private VoIP network to act as one large virtual phone system. The main benefit allows for intercom and transferring calls between sites as if all employees are in the same building.
Work from home employees - Can connect remote IP phones to their Internet connection and become an extension off their company’s main phone system via the company’s VoIP network.
Hosted or cloud-based VoIP service options - Runs on a computer server housed at the provider’s location anywhere in the world. Users remote IP phones are connected via the Internet to the provider’s facility and all calls are transported over the Internet, otherwise known as the cloud.
SIP Trunks - A Session Initiation Protocol (SIP) Trunk is a Voice over Internet Protocol (VoIP) service that connects a company's on premise telephone system to the public switched telephone network (PSTN) via the Internet. Using a SIP trunk can simplify administration and reduce costs for the organization as the SIP connection typically uses the same Internet access that is used for data. This often removes the need to install fixed line circuits such as Basic Rate Interface (BRI) or Primary Rate Interface (PRI) telephone circuits.
