SIP – What is SIP?
SIP trunking is a direct connection between your organization and an ISP. It enables you to extend VoIP telephony beyond your organization’s firewall without the need for an IP-PSTN gateway. Additionally, SIP trunks can carry instant messages, multimedia conferences, user presence information, and other SIP-based, real-time communications services. Because it is easier to configure and less expensive to design, operate, maintain, and upgrade, and because ISP’s deliver services at substantial savings, your investment in SIP trunking can give a quick and substantial return on investment. SIP is the most resilient service available for modern day telephony, allowing you many benefits that include just some of the following:
•The ability to add more channels as and when needed without the massive installation cost, as opposed to ISDN.
•As SIP channels allow your business to port your existing number(s) (even if you move premises) the end customer experience is the same.
•The lower cost of placing calls using Voice over Internet Protocol is far cheaper than over an ISDN circuit.
•Should the worst happen in the event of a disaster there will be no need for your customers to be unable to get through as SIP lines are easily diverted to any number you wish either manually or automatically.
