Call Forwarding Use Cases

  • Remote work: With the rise in remote work, call forwarding allows employees to receive work-related calls on their personal devices, ensuring they stay connected and productive while working from home or a different location.
  • Business continuity: If a business owner or employee is away from the office, call forwarding ensures that important calls are not missed by redirecting them to an alternative phone number, such as a mobile phone or another office location.
  • Load balancing: Call centers often use call forwarding to distribute incoming calls among multiple agents or locations, ensuring that no one agent is overwhelmed and that callers receive prompt assistance.
  • Device malfunction: In the event of a phone malfunction or service outage, call forwarding can be used to redirect incoming calls to a different device or phone line, maintaining communication while the issue is resolved.
  • Virtual office: For small businesses and freelancers without a physical office, call forwarding can route calls from a professional business phone number to a personal or mobile phone, creating a virtual office presence.
  • Privacy protection: By forwarding calls from a public or professional phone number to a private line, individuals can maintain their privacy and avoid sharing their personal contact information.
  • Department routing: In small to medium organizations, call forwarding can be used to route incoming calls to specific departments, ensuring that the caller reaches the appropriate person or team.
  • Time-based forwarding: Some call forwarding systems allow users to schedule call forwarding for specific times or days, ensuring that calls are directed to the appropriate destination during business hours, after hours, or on weekends.
  • Vacation coverage: During vacation or time off, individuals can forward their calls to a colleague, friend, or family member to handle urgent matters in their absence.
  • Backup plan: Call forwarding can serve as a backup plan in case of unexpected events, such as power outages or network issues, allowing calls to be redirected to an alternative location or device to maintain communication.

The history behind call forwarding

Call forwarding, also known as call diversion enables incoming calls to be redirected from the intended recipient to another destination. This service has been a crucial part of telecommunication networks for many years, with its history dating back to the mid-20th century. It's been a core FlyNumber feature from it's founding back in 2010.

  • Early beginnings (1950s-1960s): The concept of call forwarding first emerged in the 1950s and 1960s as a feature of private branch exchange (PBX) systems. PBXs were used by businesses to manage their internal telephone networks and route incoming calls to the appropriate extensions. Call forwarding was initially a manual process, where operators would physically transfer calls to the desired extension.
  • Development of electronic switching systems (1960s-1970s): The development and implementation of electronic switching systems in the 1960s and 1970s made it possible for call forwarding to become an automatic feature. The first electronic PBX, known as the Electronic Private Automatic Branch Exchange (EPABX), allowed users to program their call forwarding settings and route calls to different numbers or extensions without the need for an operator.
  • Introduction to the public telephone network (1970s-1980s): Call forwarding was eventually introduced to the public telephone network in the 1970s and 1980s. In the United States, AT&T introduced call forwarding as a service for their customers in 1974. This made it possible for residential and business customers to forward their incoming calls to another number, such as a mobile phone or a different office location.
  • Expansion of call forwarding features (1980s-1990s): Over the years, call forwarding evolved to include more advanced features, such as selective call forwarding, which allowed users to forward calls from specific numbers, and remote access call forwarding, which allowed users to activate or deactivate the service from a remote location.
  • Mobile telephony and the internet (1990s-2000s): With the rise of mobile phones and the internet, call forwarding became even more sophisticated. Mobile carriers began offering call forwarding services for their subscribers, making it easier to manage incoming calls on the go. VoIP (Voice over Internet Protocol) technology, which emerged in the late 1990s, also enabled call forwarding over the internet, allowing users to forward calls to any device with an internet connection.
  • Call forwarding and the modern era: Here at FlyNumber call forwarding has evolved to give the user multiple options. Forwarding a FlyNumber directly to a regular phone number is probably the simplest method and works well for many. For those needing something more robust using our cloud phone system is the way to go. You can forward the FlyNumber calls to multiple phone numbers, internal SIP accounts, external SIP URI's and based on different routing as well (For ex: based on the time or day or on the prefix calling the FlyNumber etc.)
