Epygi's Quadro IP PBX appliances have been designed to serve the SMB and SOHO markets along with enterprise teleworkers and companies with many small branch offices.

Epygi markets a line of feature-rich IP PBX units along with gateways that bridge IP and traditional public network telephony. Using its own IP PBX call manager software based on standard Session Initiation Protocol (SIP) technology and Digital Signal Processing (DSP) software, Epygi combines telecommunications network knowledge with emerging computer telephony protocols to deliver robust voice over Internet Protocol (VoIP) utility.


Spitfire’s SIP trunking service has been tested to operate with the Epygi range of Quadro IP PBXs enabling customers and partners to deploy a pure VoIP solution without the need for TDM gateways or ISDN lines.

Our SIP network is designed to reduce the problems of PBX’s behind NAT devices saving you time and money when deploying Epygi systems. There is no need for expensive SIP aware firewall devices or SIP Application Layer Gateways.

Our SIP trunking service offers:

  • PSTN termination and origination
  • DDI numbers from all UK exchanges
  • Porting of existing numbers from BT
  • A choice of IP bearer circuits -100Mbps Ethernet, SDSL, ADSL and ADSL2+

Why Spitfire?

We own and operate our own SIP network - we are not a reseller of someone else’s SIP trunking product.

We have been an ISP since 2000 and are full member of LINX.

Spitfire has been an interconnected CPS operator since 2001. Calls to PSTN destinations are passed over our own TDM switch with multiple interconnects to the UK PSTN network.

We are a real telephone company that have been in business for 20 years.
