One of the first ISPs and fixed line operators to launch a SIP service, Spitfire offers a complete end to end SIP service via their own IP and TDM infrastructure. Spitfire can provide a direct connection between the customers’ premises and Spitfire’s core network over an ADSL, SDSL or WES circuit.
As an Interconnected Fixed Line Operator and one of only 29 CPS Operators in the UK, Spitfire also has number ranges on all UK dialling codes, together with non-geographic number ranges, allowing them to provide one of the only fully integrated SIP services available today, delivering a genuine ISDN30e replacement. Spitfire is also involved with OFCOM and at industry level in the development of future interconnect and number porting arrangements between BT and the industry.
The service has been used by Spitfire staff at their own offices for the past year and has been in field trials for six months. Commenting on the full launch of Spitfire’s SIP Service, Tom Fellowes, Sales Director said, “We have been determined to carry out rigorous testing before launch to ensure we are able to deliver a genuinely business class service to our clients. Providing the IP circuit ourselves allows us to control the quality of service delivery to the customer. We have also developed a range of back up options by combining a SDSL circuit with an ADSL circuit, all at significantly reduced costs compared with ISDN30e.”
Full interoperability testing and accreditation has been completed with the Avaya IP500 / IP Office product range. Spitfire and Panasonic are also in the later stages of interoperability testing in Japan and at Spitfire’s labs. A range of SIP equipment has also been fully tested, including Vegastream, PBXnSIP, Snom, Counterpath and Cisco IP phones. There is a planned schedule of interoperability testing for other vendors over the next 12 months.
