Businesses that have recently installed or upgraded their phone system will be aware of it's VoIP capability and will want to make some or full use of the VoIP capability and not only communicate over IP within the enterprise, but also outside the enterprise. A SIP trunk provided by an Internet Telephony Service Provider to connect to the traditional PSTN network is the solution. Unlike in traditional telephony, where bundles of physical wires were once delivered from the service provider to a business, a SIP trunk allows a company to replace these traditional fixed PSTN lines with PSTN connectivity via a SIP trunking service provider on the Internet.
SIP trunks can offer significant cost-savings for enterprises, eliminating the need for local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces). .
Our SIP Trunk service provides a simple, cost effective solution for business customers that want a VoIP Telephone Service for use with ther SIP enabled VoIP Phone System, or for use with legacy PSTN and ISDN systems with the use of a SIP VoIP Gateway. SIP Trunks provide a competitive solution for extra telephone lines or for adding extra DDI Capability or back-up of traditional telephone line solutions.

VxDSL - Voice Only DSL Service
VxDSL Voice Only DSL
VxDSL is our own xDSL voice-only service which guarantees network quality for SIP trunks. VxDSL utilises BT ATM coupled with Voice Flex's own MPLS network to provide unparalled levels of service and quality. This has been done before but on expensive private MPLS circuits which isn't feasible for mass market penetration. Voice Flex's VxDSL removes the uncertainty that the internet brings to voice; we don't use the internet, just internet technology. No traffic over the internet.
