What is Session Initiation Protocol?Despite more and more reliance being placed on Email and other forms of communication, we all still rely on telephones to perform our day-to-day business. Historically companies have only had one option – a PBX phone system connected to either normal telephone lines (PSTN) or via an ISDN line. This has meant large capital expenditure and high monthly running costs. Voice over Internet Protocol (VoIP) is increasingly becoming the preferred telephone system for all sizes of business. It has many clear benefits over traditional telephone systems, not least of which is cost.
SIP Trunking, (Session Initiation Protoco)l is a Voice Over Internet Protocol that internet telephony service providers use to deliver unified communications and telephone services to customers. In traditional telephony, bundles of physical wires are delivered from the service provider to a business, but with a SIP trunk you will be able to replace your fixed PSTN or ISDN lines with connectivity via your existing Internet connection.
