Hosted IP Telephony - Cisco is a service that provides IP Line and IP Trunk services to businesses and Government over a combination of suitable IP based WANs and LANs. It should be noted that the WAN/LAN infrastructure does not form part of the Hosted IPT - Cisco service offering and must be purchased separately, see other sections of the BT Price List for information.

Customers can opt to deploy Hosted IPT - Cisco services in conjunction with either existing or new Featurenet services (See Section 21:Part 1:for details) to realise a single dual technology (TDM/IP) voice network.
