IP Trunking
Cable&Wireless Worldwide IP Trunk routes your IP voice traffic via the PSTN (Public Switching Telephony Network), providing a cost-effective, flexible and safe route to full voice and data convergence.
Converged IP networks offer greater flexibility, powerful collaboration tools, more interfaces with customers and lower overheads. However, not all businesses are ready to make the leap to a fully converged network.
IP Trunk bridges that gap. It lets you connect your IP-enabled PBXs via our central PSTN using IP, so there’s no need for a separate voice line. You also benefit from free ‘on-net’ calls, support for your current dialling plan, and easier management. As IP Trunk integrates fully with TDM (Time Divisional Multiplexing), you maximise the return on your legacy investment and can migrate when it suits you.
How It Works
Cable&Wireless Worldwide IP Trunk routes calls from IP-enabled PBXs to other IP PBXs through the PSTN, via a soft switch.
By routing voice and data through a single network, IP Trunk eliminates the need for costly separate voice and data circuits between your sites.
The soft switch can connect traditional PBXs, IP PBXs and traditional or IP Centrex systems, to provide IP, digital or analogue telephony. This flexibility lets you upgrade to full IP voice lines and data convergence, making the most of your legacy investment and at a pace that suits you.
Benefits
Save money. Your 'on-net' calls are free, and there are no Moves, Adds and Changes cost. You also ensure a longer life and better return from your legacy investment.
Simplify complexity. With a central PSTN breakout, there are no separate PSTN lines at each site; just a single network to manage. You can manage your IP and TDM estate centrally, including your dial plan. IP Trunk also integrates easily with your existing VPNs.
Achieve more. IP Trunk moves you towards true convergence, combining voice onto existing data links. It encourages 'on-net' short dial calls and supports the features you find most useful, such as call hold, transfer and forwarding, and conferencing.
C&W Worldwide IP Trunk lets you mitigate risk, control costs and enjoy the benefits of IP voice – all at your own speed.
