Spitfire’s SIP Trunking has been designed as an ISDN30 and ISDN2 replacement offering business quality secure telephony at typically a third less than the monthly rental cost of an equivalent ISDN service.
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 the UK’s widest range of reduced price SDSL circuits, ADSL or WES circuits.
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.
Commenting on the Panasonic accreditation for Spitfire SIP Trunking, Tom Fellowes, Sales Director said, “We have now completed interoperability testing with both Panasonic and Avaya phone systems as well as having tested and approved our SIP service on Asterisk and a number of other SIP systems. We been determined to carry out rigorous testing 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 services. Spitfire SIP Trunking is now a mature technology that customers can adopt as a cost effective alternative to ISDN30e with full confidence.”
