PBX connects telephone extensions of any company to external public telephone network and mobile networks. An IP (Internet Protocol) PBX (Private branch exchange) is a PBX that provides audio, video, and instant messaging communication through the TCP/IP protocol stack for its internal network, and which interconnects its internal network with the Public Switched Telephone Network (PSTN) for telephony communication.

Companies can enjoy immediate savings using IP-PBX versus traditional method of calling.

Global Voice Solution

A comprehensive and cost effective business communications solution for multiple locations/ nations.

VoIP (Voice over Internet Protocol) gateways can be combined with traditional PBX functionality enabling businesses to use their managed intranet to help reduce long distance expenses, to enjoy the benefits of a single network for voice, data, and advanced CTI features or to be used on a pure IP system which in most cases provides greater cost savings, greater mobility, and decreased redundancy.

SEVAK Global Voice Solution allows companies to easily integrate their existing voice infrastructure by building a virtual voice network over SEVAK’s Global IP (Internet Protocol) infrastructure (Voiznet) without immense investment costs.

IP Phone

IP Phone uses Voice over IP (Voice over Internet Protocol - VoIP) technologies for placing and transmitting telephone calls over an IP network, such as the Internet, instead of the traditional public switched telephone network (PSTN).
