    • Resilient connections into 14 BT exchanges for inbound voice, 2 wholesale distributors.
    • Multi carrier access for outbound traffic
    • Failover routing, supported by our layer 2 IP network
    • Enterprise class IDS monitoring (intrusion detection)


We offer low cost-per-minute prices for all destinations because we are directly connected to all the significant UK carriers.
