Frequently Asked Questions
Celebrating its tenth anniversary this year, Stripe 21 is a Tier 2 ISP with its own infrastructure and Autonomous System Number (AS8838) allocated by RIPE NCC, the international Internet Registry. Unifying and converging both voice and data skill sets with its dynamic, dedicated and innovative team, Stripe 21 bridged the gap between “Net-heads” and “Bell-heads” in the late 1990’s. Its team were the first to bring Quality of Service over Broadband to the UK market in 2002. This enabled the delivery of leased-line Internet performance over broadband and the replacement of expensive MPLS data networks with better, faster, cheaper VPN services. However, arguably the biggest step forward enabled us to guarantee the call quality, security and reliability of digital ISDN lines over a VoIP service – and therefore meet the attractive VoIP price point for call charges and line rentals on our own fully IEEE and ETSI compliant ISDN service.
Our SIP trunks and ISDN lines can be delivered anywhere in the UK at the attractive VoIP price point. Delivered from our mirrored network across two London data centres, our Service Level Agreement guarantees the highest levels of quality, security, reliability and availability from any Service Provider in the UK.
Our VoIP services are delivered as a Cisco managed service on a guaranteed private GigE network covering more than 95% of the UK population. We manage the contention ratio at 1:1 for voice services. Zero contention combined with other technical innovations guarantees the quality, security and reliability of each call will meet or exceed that of the ISDN service it replaces, at the much cheaper VoIP price point.
Stripe 21 has many high-profile media Internet clients where IP traffic volumes surge whilst TV shows are broadcast. Consequently our Internet backbone has to be massively overpowered and run with zero contention to cope with these high burst levels without any pressure. Combined with our low (5:1) or zero (1:1) contention access networks and Cisco technologies , we offer the highest performance lowest cost managed Internet connectivity in the UK.
