### What Does It Mean for a Phone Number to Support VoIP?
A phone number that supports VoIP can be used to make and receive calls over the internet. This means that instead of using the traditional Public Switched Telephone Network (PSTN), calls are transmitted digitally as data packets through IP networks. The phone number itself acts as an identifier to route calls to and from VoIP devices or software.

### How Are VoIP-Enabled Numbers Provisioned?
1. **Direct VoIP Numbers:** Some phone numbers are specifically issued by VoIP service providers (like Twilio, RingCentral, Vonage, or Google Voice). These numbers are designed to work primarily with internet-based calling services.
2. **Ported Numbers:** Existing traditional phone guatemala mobile phone number list numbers (from landlines or mobile carriers) can often be **ported** to a VoIP service. After porting, the number fully supports VoIP calls.
3. **SIP Trunking:** Businesses can connect their existing PBX phone systems to the internet through SIP trunking, which uses VoIP technology. The associated phone numbers in this setup support VoIP calling.
