Most new phone systems use IP as a converged technology, reducing complexity, cost and increasing the number of features. VoIP.co.uk offer a SIP Trunking service directly compatible with most new systems and when combined with our Network Access products produce a more flexible cheaper alternative to ISDN and extends the reach of wideband technology beyond the installation site.
Traditional ISDN services are expensive and inflexible. VoIP.co.uk ISDN replacement services allow you to experience the advantages of a VoIP.co.uk SIP Trunk, without having to replace the entire phone system. Advantages such as reduced channel cost line rental, flexible capacity, low cost worldwide call rates, configurable caller ID and per-seat billing are enabled while exceeding the reliability and stability of ISDN when used with VoIP.co.uk Network Access products.
Our SIP gateway solutions are available for H323/SIP, ISDN PRI, ISDN-BRI and POTS based Key Systems, with an option to keep the existing connection into the current operator. This allows for the timely number porting of inbound DDI’s. Please contact our pre-sales team for advice.
