Do you need a virtual telephone line?

A virtual telephone line is a complete replacement for traditional office telephone exchanges. It works via the Internet, and the servers of the providers providing this service are responsible for the functionality. All you need to do in the office is to set up the equipment in the workplace. Virtual PBXs are becoming more widespread. But many still do not know what it is. It is for these people that our article is designed.

A classic virtual telephone line is a digital device that connects multiple internal and multiple external lines. She switches internal subscribers, knows how to receive and redirect calls from outside. Each such block is designed for a strictly defined number of jobs. To increase this number, expansion units or new PBX units are purchased, which leads to high costs. And the functionality of the office stations is not the most impressive.

There are also software virtual telephone lines that run on office computers. Asterisk is a typical example of this. This is a powerful software package that requires certain knowledge for administration. A beginner will not be able to cope with this PBX, and stability, in the absence of work experience, will be low. If something happens to the station, the entire office will be left without communication, including external.

What is a virtual telephone line

The virtual telephone line operates on the servers of SIP providers. It is the providers who are responsible for its work. To connect to the station, you only need a reliable office Internet channel. Through it, the equipment installed at workplaces is connected to the station - these are IP phones, VoIP adapters and computers with installed softphones. All this equipment communicates with the equipment of SIP providers.

Cloud virtual telephone line works through an Internet channel laid in each office. Calls coming from outside arrive at the provider's equipment, after which they are directed to certain workplaces. If the function of distribution of voice calls is enabled in the PBX, then they are automatically distributed between a certain segment of internal numbers.

Intra-office calls are also processed on the provider's equipment - it is a kind of switch. The IP-phone installed at the workplace contacts the server, after which the server finds the called subscriber's phone in the network and directs the call to it - after picking up the handset, the connection is established.
