Voice over IP (VoIP)

VoIP is the transmission of voice traffic over a wide area network or the internet using the IP signalling standard. It provides least cost routing between two sites. An IP Gateway is installed for an existing telephone system, which converts normal circuit-switched telephony signal into IP for transmission over the data network, such as a private data network between two sites.This means that businesses can continue to use a reliable, fully featured circuit-switched telephone system, with an IP routing option for voice and data over the company's private network

Inter-branch phone calls     The main business benefit of VoIP is that it allows a multi-site organisation to transmit voice over the company's existing wide area data network, saving the cost of using the PSTN (public switch telephone network) to make inter-branch phone calls. This is usually set up as a least cost routing option, giving seamless access to the IP network.

Separate sites are treated as one VoIP Gateways also allow separate sites to be treated as one, with integrated voice and data, application sharing and a single point of access for system management.
