A Modern Evolution of Phone Numbers

Traditionally, phone numbers were tied to fixed physical lines in a specific location. With the rise of mobile networks, numbers began representing SIM cards and verified subscriber identities.

Today, phone numbers can also be fully virtual.
A virtual number is assigned to a SIP or VoIP account instead of a physical line. Calls can be forwarded to:

• A softphone app

• A VoIP device

• Any fixed or mobile number worldwide

• Contact centers and cloud PBX systems

This gives complete freedom — your number travels with you, not with your hardware.

Global Availability, Local Presence

Virtual numbers can be acquired from 150+ countries, allowing businesses and individuals to operate globally while maintaining a local identity.

Example:
A business owner in Brazil doing business in Japan can activate a Tokyo virtual number that rings directly in Rio de Janeiro.

This unlocks:

• Local customer trust

• Higher answer rates

• Global expansion without physical offices

• Lower operational costs

Tellimon makes this process instant, seamless, and scalable.

Understanding Regulations

Virtual numbers are subject to local telecom rules, which vary by country. These regulations ensure legal, secure, and compliant use.

Common regulatory scenarios:

🇮🇳 India

Local numbers cannot be used for person-to-person communication inside India. Strict limitations apply.

🇩🇪 Germany

City-based numbers often require a verified local address within the same city as the number. This mirrors traditional PSTN rules.

🌍 Other Countries

Some require identity verification; others allow open access. Requirements can include:

• Proof of address

• Business registration

• End-user identity checks (KYC)

Tellimon handles compliance automatically, ensuring you and your customers meet local rules before activation.
