Voice over IP is a digital telecommunications format - the analogue voice signal is digitalised into data packets, sent, and then reconverted back into a voice signal at its destination. VoIP uses TCP/IP to travel across either a private network (Intranet) or across the Internet to its destination. The TCP/IP networks are made of IP packets containing a header (to control communication) and a payload to transport data.
With VoIP it is possible to talk to one or more persons at once, and at the same time, you can exchange data with the people you are talking with - sending images, documents, graphs and videos, and all at a fraction of the cost of a conventional telephone call.
Telrad Connegy offer a range of solutions and the system supports the SIP (Session Initiation Protocol). SIP is emerging as the protocol of choice for setting up conferencing, telephony, multimedia and other types of communication sessions on the Internet. SIP may also be used for new types of communications, such as instant messaging and application level mobility across various networks, including wireless, and across user devices.
