From BCS OSSG Events. Fruther details from  http://ossg.bcs.org/2010/03/22/open-source-in-telecommunications-london-220410/

The telecommunications industry has a deep and complex history, where proprietary technologies have featured heavily, the barrier to entry has typically been high and the majority of research and development led by incumbent network operators and equipment providers. More recently we are seeing this change with the growing popularity of IP telephony, the availability of open source softswitch implementations and the aggressive adoption of Linux in mobile handsets, home router/gateways and other customer-premises equipment (CPE). However, whilst the opportunities are significant, many challenges to open source adoption remain and the telecoms environment presents its own set of unique problems.

The BCS Open Source Specialist Group has joined forces with BT to bring an event that seeks to provide insights into the state of the art of open source in telecommunications. The event will consist of a series of talks followed by a panel-led, open discussion centred upon the opportunities that exist and the challenges that the telecommunications industry and open source community faces.

The event will be held at the BCS Central London Offices, First Floor, The Davidson Building, 5 Southampton Street, London WC2E 7HA (http://www.bcs.org/upload/pdf/london-office-guide.pdf) on Thursday 22nd April, 2010, from 10.00 to 17.30.
