IP Telephony
IP telephony is becoming the most popular type of service for both large companies and individuals. The advantages of negotiations over the Internet are obvious: high quality of communication, ease of use and, most importantly, low cost of both incoming and outgoing calls (the difference can be tens of times compared to analog telephony). IP telephony services combine voice and data on one network and offer cheap international and long distance calls, as well as a range of value-added communications services.
