BT has won a contract with the European Commission (EC) to provide voice services across 21 of its institutions.
The seven-year contract, worth €15 million, will provide services to bodies such as the EC, European Council and European Defence Agency.
The fixed line services, using the BT One Voice SIP portfolio, will be used at sites in Belgium, Luxembourg and Strasbourg.
This is the second contract BT has won this year with the EC; the first, signed in March, is worth around €55.7 million over 5 years. This will provide internet access to all major European institutions, agencies and bodies in the 28 member states.
The UK telecoms provider has provided communications to the European Union (EU) for over a decade. In 2004, BT won a contract worth €162m to supply external network services to 15 EU institutions.
Corrado Sciolla, President Europe and Global Telecom Markets, BT Global Services, said: "We are very proud of our relationship with the EU institutions, where we provide a wide range of networked IT services. Today’s contract aims at improving fixed line communications within those institutions.
"Voice services might sound old-fashioned, but they are absolutely critical to everyone. By modernising the technology, we enable the EU to manage its communications infrastructure much more effectively, combine voice with other media streams and achieve cost-savings.
"We are looking forward to again putting our global expertise at the service of the EU, its institutions and its citizens."
