At its simplest, SIP Trunking provides ISDN replacement into existing PABX’s to provide cheaper access charges for the customer.

SIP Trunking is about more than cost saving on access. We see it as a critical aspect in unifying all elements of the customer’s telecom infrastructure. This provides a homogenous communications strategy across all the customer’s platforms and sites and retains existing investment. SIP Trunking extends cost reduction by overlaying next generation Intelligent Network services. This includes sophisticated queuing, inbound call statistics, centralised reception, remote working, distributed call centers and desk-to-desk dialing.
