These numbers are often used to route calls to the user's preferred phone number(s) and can be assigned to both landline and mobile devices. 

• Flexibility in Call Routing: Virtual phone numbers can be set up to forward incoming calls to one or more pre-set telephone numbers, which can include landlines, mobile phones, or VoIP systems.

• Not Tied to a Specific Location: Unlike traditional phone numbers that are typically associated with a specific geographic area or city, virtual numbers can be used regardless of the user's location. This makes them ideal for businesses aiming to establish a presence in various regions without needing physical offices there.

• Use in Business: They are commonly used by businesses for customer service lines, as they allow for handling incoming customer calls more efficiently. Businesses can use them to create local customer service numbers in different cities or countries while managing all calls centrally.

• Privacy and Security: Individuals might use virtual numbers to keep their personal numbers private or for added security.

• Integration with Business Systems: Virtual numbers can integrate with business VoIP systems and Unified Communications as a Service (UCaaS), providing advanced features like call recording, voicemail, conference calling, and detailed analytics.

Virtual phone numbers offer versatility and practicality, especially for businesses looking to establish a local presence in multiple locations or for individuals seeking more control over their calling options and privacy.
