ECTION
Voice over IP (VoIP) is a technology that converts speech into data
packets and transmits these packets over TCP/IP networks. The
technology also facilitates compression and silence suppression to reduce
network bandwidth demands.
As most organizations already have existing data networks in place,
considerable cost savings can be achieved by utilizing spare bandwidth on
these networks for voice traffic.
NEC SL1100 supports the use of IP Phones. These telephones provide
the same functionality as a multiline telephone but use the data network
rather then the traditional telecoms infrastructure. This can reduce costs
and allow the use of NEC SL1100 telephones in locations that would not
normally be supported by multiline telephones.
