London, UK, September 14, 2010 — Metaswitch today announced that it has been selected by Cobham Defence Communications to provide its DC-SIP protocol software for use in the Cobham designed VIS-X Intercom System which was recently selected by the US Army as its next generation vehicle intercom system (VIS). The Metaswitch DC-SIP protocol will provide VoIP for the Cobham system where reliability in extreme conditions is paramount.
