Internet Telephony Services Providers' Association

Officially launched in December 2004, its existing founder members are Gradwell Dotcom Ltd, Magrathea Telecommunications Limited, Telappliant, Timico Ltd, Voicenet Solutions Ltd, Voipfone and XConnect  and corporate members such as BT and Gamma. ITSPA aims to promote competition and self-regulation in order to encourage the development of a flourishing and innovative VoIP industry.

ITSPA's main activity is in making representations on behalf of the industry to Government bodies, such as the Home Office, the Department for Business, Enterprise and Regulatory Reform (former DTI) and Ofcom.
