The price of international mobile phone calls could fall following BT Ignite's decision to open up its network to other operators.
Last year BT launched Mobile To Mobile (MTM) routing, and mobile firms are now able to use the service via any of the gateways in The Netherlands, Belgium, Ireland, Spain, Germany and the UK.
It will also be deployed in eastern Europe from 2003, starting in Hungary and the Czech Republic.
Peter Morley, vice president of voice services for carriers at BT Ignite, said: "Previously, mobile operators have mainly been judged on the quality of service [QoS] of calls routed through to pan-European destinations.
"In the current economic climate, operational efficiency is the key to accelerated revenue growth, especially in international mobile voice services."
The MTM service includes stringent QoS and Service Level Agreements. It also includes high answer seizure ratios, short post dial delays and, for the first time, guaranteed Calling Line Identification presentation.
