How do Virtual Numbers work?
Depending on the region, a DEF number can have different formats (+1, +44), be mobile or city, intercity and international, etc. It differs from ordinary numbers only in the connection method. The chain is the following:
- calls are received by the provider;
- the provider addresses them to the server;
- and from there, they are redirected to the specified devices.
This service is based on the transmission of data over the Internet. SIP (Session Initiation Protocol) is the most common and universal protocol for data transfer. This protocol processes and distributes calls according to the “client-server” algorithm, allowing data to be exchanged over the Internet. The SIP protocol converts analog voice signals into digital ones, compresses them, and transmits them over the IP network to the recipient. At the output, they are decoded and converted back to analog.
This data transfer scheme allows users to significantly reduce communication costs. Moreover, only used voice traffic is paid, pauses and waiting time in the process of telephone communication are not counted. Thus, virtual numbers today are the most cost-effective option for building intra-corporate communication networks.
Call forwarding can be configured to a mobile or landline number. This service is paid, but very affordable. This makes toll-free numbers the most convenient for businesses and individuals who travel a lot or work remotely but want to always stay in touch without overpaying for long-distance calls and roaming.
When purchasing a multichannel number, all branches of the company, regardless of the city or country in which they are located, will be able to use it. This feature allows businesses to create the effect of presence in different countries and regions, increasing customer loyalty, and also simplifying the conduct of international business.
To use all the benefits of this service, just select the number according to the required geography and install a softphone or a special application (SIP client) on your mobile, tablet, or PC.
