With TMG's IP Voice, you can create the voice solution you need, knowing that it will adapt to meet the changing needs of your organisation. The service will support an integrated mix of:

Legacy & IP PBX's
Site-based (PBX) and network-hosted (Centrex) systems.
Analogue, digital and IP telephony equipment. Call routing via PSTN and VPN, with guaranteed voice quality.

You can connect your current voice equipment seamlessly into TMG's IP Voice solution while maintaining a single dial plan (short-code desk-to-desk dialling) and without sacrificing any functionality, features or voice quality.

You'll notice immediate savings in call spend because:
You don't pay for usage, if calls stay on your VPN (on net calls) - all inter-organisational calls are covered by a flat monthly charge.
Our rates for calls that break out of the PSTN (off-net calls) are very competitively positioned against BT's tariffs

How it works
TMG's IP Voice, shares a common infrastructure with Cable & Wireless's IP-VPN quality of service, a dedicated IP virtual private network service based on cutting-edge multi-protocol label switching (MPLS) technology. This enables voice and data to be carried on the same network via a single access circuit.

The voice VPN is enabled by software-implemented voice switches (soft switches) in the MPLS network.

The soft switches
Provide carrier class reliability and scalability.

Make it possible to do away with site-based call routing, by enabling network-level call routing.

Support all network and business telephony features that you currently rely on in your day-to-day activities

The soft-switches can also integrate a network of traditional PBX's, IP PBX's and traditional IP Centrex systems to deliver IP, digital or analogue telephony where most appropriate.
