Virtual Private Number
A virtual number, also known as direct inward dialing (DID) or access numbers, is a telephone number without a directly associated telephone line. Usually, these numbers are programmed to forward incoming calls to one of the pre-set telephone numbers, chosen by the client: fixed, mobile or VoIP. A virtual number can work like a gateway between traditional calls (PSTN) and VoIP. Subscribers to virtual numbers may use their existing phones, without the need to purchase additional hardware, i.e. use the numerous available software. A virtual private number is a telephone number that forwards incoming calls to any of a number of pre-set telephone numbers. These are also called a follow-me number, a virtual telephone number or (in the UK) Personal Number. Usually a virtual telephone number can be set to forward calls to different telephone numbers depending on the time of day and the day of the week using time of day routing; for example, between 9 and 5 on working days incoming ca ...

Telephone Number
A telephone number is a sequence of digits assigned to a landline telephone subscriber station connected to a telephone line or to a wireless electronic telephony device, such as a radio telephone or a mobile telephone, or to other devices for data transmission via the public switched telephone network (PSTN) or other public and private networks. A telephone number serves as an address for switching telephone calls using a system of destination code routing. Telephone numbers are entered or dialed by a calling party on the originating telephone set, which transmits the sequence of digits in the process of signaling to a telephone exchange. The exchange completes the call either to another locally connected subscriber or via the PSTN to the called party. Telephone numbers are assigned within the framework of a national or regional telephone numbering plan to subscribers by telephone service operators, which may be commercial entities, state-controlled administrations, or ...

Virtual Office
A virtual office is part of the flexible workspace industry that provides businesses with any combination of services, space and/or technology, without those businesses bearing the capital expenses of owning or leasing a traditional office. Virtual office services started in the 1960s as serviced offices and have evolved with technology to include a wide variety of personnel, physical space, digital storage and communication services. Customers pay a contract fee for these services which may be offered à la carte, as packages or membership subscription. The concept is popular with companies of all sizes, including self-employed entrepreneurs. One of the primary allures of the virtual office is the flexibility it offers for employees and freelancers to work from a satellite office, home office, remote location or even on-the-go via a mobile device. At the same time, a company can offer its clients and employees a stable home office with access to amenities such as receptionist, co ...

Unified Messaging
Unified messaging (or UM) is a business term for the integration of different electronic messaging and communications media ( e-mail, SMS, fax, voicemail, video messaging, etc.) technologies into a single interface, accessible from a variety of different devices. While traditional communications systems delivered messages into several different types of stores such as voicemail systems, e-mail servers, and stand-alone fax machines, with Unified Messaging all types of messages are stored in one system. Voicemail messages, for example, can be delivered directly into the user's inbox and played either through a headset or the computer's speaker. This simplifies the user's experience (only one place to check for messages) and can offer new options for workflow such as appending notes or documents to forwarded voicemails. Unified messaging is increasingly accepted in the corporate environment, where it's generally seen as an improvement to business productivity. Unified messaging ...

Private Branch Exchange
A business telephone system is a multiline telephone system typically used in business environments, encompassing systems ranging in technology from the key telephone system (KTS) to the private branch exchange (PBX). A business telephone system differs from an installation of several telephones with multiple central office (CO) lines in that the CO lines used are directly controllable in key telephone systems from multiple telephone stations, and that such a system often provides additional features related to call handling. Business telephone systems are often broadly classified into key telephone systems, and private branch exchanges, but many hybrid systems exist. A key telephone system was originally distinguished from a private branch exchange in that it did not require an operator or attendant at the switchboard to establish connections between the central office trunks and stations, or between stations. Technologically, private branch exchanges share lineage with centra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Personal Communications Service (NANP)
In telecommunication, a personal communications service is defined by the Alliance for Telecommunications Industry Solutions (ATIS) as "a set of capabilities that allows some combination of personal mobility, terminal mobility, and service profile management". Personal communications services use a special non-geographic area code of the format ''5XX'' for assigning telephone numbers for service instances. The designation of the 5XX area code format was authorized by the United States Federal Communications Commission, and introduced into the North American Numbering Plan in 1995. United States In 1995, AT&T introduced a "follow-me" service under the brand name of ''AT&T True Connections'' using area code 500. It was designed to replace the '' AT&T EasyReach 700'' service. Other local exchange carriers and interexchange carriers introduced similar competitive services. AT&T True Connections service was not well received.

North American Numbering Plan
The North American Numbering Plan (NANP) is a telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1 and has the international calling code ''1''. Some North American countries, most notably Mexico, do not participate in the NANP. The NANP was originally devised in the 1940s by the AT&T Corporation, American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone operators in North America. The goal was to unify the diverse local numbering plans that had been established in the preceding decades and prepare the continent for direct-dialing of calls by customers without the involvement of telephone operators. AT&T continued to administer the numbering plan until the breakup of the Bell System, when administration was delegated to the North American Numbering Plan Administrator (NANPA), a service that has been procured from the private sect ...

Toll-free Number
A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls. For the calling party, a call to a toll-free number from a landline is free of charge. A toll-free number is identified by a dialing prefix similar to an area code. The specific service access varies by country. History The features of toll-free services have evolved as telephone networks have evolved from electro-mechanical call switching to computerized stored program controlled networks. Originally, a call billed to the called party had to be placed through a telephone company operator as a collect call, often long-distance. The operator had to secure acceptance of the charges at the remote number, or even transfer that decision to a long-distance operator, before manually completing the call. Some large businesses and government offices received large numbers of collect calls, which proved time-consuming for operators and the callers. Manual toll-free systems Pri ...

Direct Inward Dial
Direct inward dialing (DID), also called direct dial-in (DDI) in Europe and Oceania, is a telecommunication service offered by telephone companies to subscribers who operate a private branch exchange (PBX) system. The feature provides service for multiple telephone numbers over one or more analog or digital physical circuits to the PBX, and transmits the dialed telephone number to the PBX so that a PBX extension is directly accessible for an outside caller, possibly by-passing an auto-attendant. Plain old telephone service For direct inward dialing service, the telephone company provides one or more trunk lines to the customer for connection to the customer's PBX, and allocates a range of telephone numbers to the customer. Calls to such numbers are forwarded to the customer's PBX via the trunks. As calls are presented to the PBX, the dialed telephone number is signaled to the PBX with Dialed Number Identification Service (DNIS) using a prearranged, usually partial format, e.g., ...
