What is IP telephony?

IP telephony is a technology for transmitting a voice signal over wireless Internet channels. Unlike analog and mobile communications, communication through the World Wide Web does not require telephone lines. You can make calls from almost any communication device (SIP phone, device with VoIP gateway, PC, laptop, smartphone).



The main advantage of IP-PBX over alternative communication methods is the cost of calls. Signal transmission over the Internet is on average 70% cheaper than over wires.
In addition, virtual PBXs based on IP-telephony support a number of useful functions that are not available with a regular telephone.


Data exchange protocols using this technology are based on the formation of info packets without organizing a direct connections between subscribers.
The interlocutors voice is encrypted into a digital signal, transmitted via the Internet and again converted into an analog form for the receiving party.


You save up to 90% of expenses on communication services due to the use of inexpensive Internet channels. Moreover, virtual numbers are not tied to a physical address and remain with the owner when moving to another city. An unlimited number of new numbers are added as the staff grows.
