An IP (Internet Protocol) PBX (Private branch exchange) is a business telephone system designed to deliver voice over a data network and interoperate with the normal Public Switched Telephone Network (PSTN).
IP-PBX has become a real breakthrough in the modern technologies as it allows transferring various types of data. IP-PBX is especially useful for business enterprises that need to maintain constant contact with customer and affiliates nationally and internationally.
IP-PBX is the way to monitor your business throughout the world.
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, enjoy the benefits of a single network for voice and data and advanced CTI (Computer Telephony Integration) features or be used on a pure IP system which in most cases give greater cost savings, greater mobility, and increased redundancy.
Open-Alt provides IP-PBX solutions based on world’s famous open source telephony engine and tool-kit “Asterisk”. Offering flexibility unheard of in the world of proprietary communications, Asterisk empowers developers and integrators to create advanced communication solutions.
Why Use IP-PBX?
Traditional PBX are limited to the number of trunk lines and extensions connected with them physically where separate wiring is required for analog telephony.
