Hosted call server
We offer two main IPT options:

Access to a centrally hosted network call server maintained by BT, eliminating the need to buy your own IP PBX
If you have already invested in a traditional PBX, you can connect to our IPT platform for full WAN convergence

On-net calling (VoIP terminal to VoIP terminal)
On-net calls to other BT VoIP users are free, dramatically reducing your voice call bill. Forced on-net is part of the Multimedia VoIP service.

Off-net calling (VoIP terminal to PSTN phone)
PSTN access is provided within BT’s core network, with no need for additional gateways or PSTN lines. Calls to the global PSTN are priced at competitive rates.

BT hosted IPT application domain
This central infrastructure is maintained by BT and provides:

Fire walling and NAT of customer IP address space
Dialling plan address translation (private and public routing tables)
Managed public Call Servers for VoIP call routing and feature provision
Management networks for monitoring and performance measurement
Distributed gateways to the PSTN for high availability
Billing infrastructure for one off, recurring and off-net (public call) usage charging
Miscellaneous service resources for ad hoc conferencing, music and announcements

Outstanding security:
BT’s IPT services are protected with the same security measures we use on our own core network. There is no fear of hacking or eavesdropping.
Fully managed round the clock service:
All network hardware and software is constantly monitored and maintained and our expert support team is always on hand to offer advice.
