We are a UK membership-led organisation that represents companies who provide or resell business and residential customers voice services over data networks (VoIP) as well as other “over the top” applications including instant messaging and video. The membership is a mixture of network operators, service providers, resellers, suppliers and consultants involved in a sector that is diversifying rapidly from just voice services to other innovative IP applications.
