Spitfire SIP Trunking completes interoperability testing

Spitfire, the Internet Telephony Service Provider, has completed interoperability testing and accreditation for its SIP Trunk service with the Epygi IP PBX range, marketed in the UK by Electronic Frontier Ltd.

Designed as an ISDN30e and ISDN2e replacement, Spitfire say their 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 only 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.

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.

In addition to Epypi, Spitfire SIP Trunking successfully completed interoperability tests with comms equipment from Asterisk, Avaya, Panasonic, PBXnSIP, Solutions 11, Vegastream, Snom, Polycom, IP Cortex, Linksys and Counterpath.

Commenting on the Epygi accreditation for Spitfire SIP Trunking, Tom Fellowes, Sales Director said, “Spitfire SIP Trunking is now a mature technology that customers can adopt 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.”

For Electronic Frontier, Conor McCann, General Manager said, “The Epygi brand is developing rapidly as a respected business class IP PBX. In the demanding environments in which they are used, Epygi devices rely on good quality, reliable SIP Trunking services. Having worked closely with Spitfire to ensure interoperability on their network we are delighted, therefore, to be working with them as an approved good quality provider of business class SIP Trunking services for the Epygi range.”
