Designed as an ISDN30e and ISDN2e replacement, Spitfire’s SIP Trunk typically offers business quality secure telephony at up to 50 percent less than the monthly rental cost of an equivalent ISDN service. As one of the few ISPs and fixed line Operators to offer a SIP Trunk service, Spitfire offers a complete end-to-end SIP service via its 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 SDSL, ADSL or Ethernet circuits, including Bonded xDSL connections.
As an Interconnected Fixed Line Operator and one of only 29 CPS Operators in the UK, Spitfire has number ranges for 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.
In addition to Sark UCS, Spitfire SIP Trunks successfully completed interoperability tests with comms equipment from 3CX, Asterisk, Avaya, Counterpath, Epygi, IP Cortex, Linksys, Panasonic, Patton, PBXnSIP, Polycom, Solutions 11, Snom, Trixbox and Vegastream.
Commenting on the Sark UCS accreditation for Spitfire SIP Trunks, Tom Fellowes, Sales Director said, “As a mature technology our customers can adopt Spitfire SIP Trunks as a cost effective alternative to ISDN30e with full confidence. 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 to ensure that Spitfire SIP Trunking offers business class voice telephony for our customers. We are extremely pleased to add Sark to our range of approved PBXs and have been very pleased with the performance of the system and the support provided to our partners.”
