How do virtual phone numbers operate?

[liza89]

Virtual phone numbers are telephone numbers that are not directly tied to a specific phone line or physical location. Instead, they operate using internet-based communication systems, most commonly through Voice over IP (VoIP) technology. These numbers can forward calls to any device—landline, mobile, or computer—making them highly flexible for both personal and business use.

1. What Are Virtual Phone Numbers?
A virtual phone number looks like a regular phone number, with a country code and area code, but it functions through a cloud-based telephony system rather than traditional copper or mobile lines. When someone dials a virtual number, the call is routed through the internet to a designated device or service, depending on the settings configured by the user or organization.

Virtual numbers can be:

Local numbers (tied to a specific city or area code)

International numbers (for use in cross-border communications)

Call Initiation: The caller dials the number as usual.

Cloud Routing: The number is registered with a virtual phone service provider (like Twilio, Google Voice, RingCentral, or Grasshopper).

Call Forwarding: The provider uses VoIP to forward the call to the desired endpoint—this could be a mobile phone, desk phone, or even a computer or app.

User Interaction: The recipient answers armenia mobile phone number list the call, which appears to come from the virtual number.
