The Internet Telephony Service Providers Association (ITSPA) is a British body representing providers of Internet Telephony services (VoIP).

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 ^[1] 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.

As a trade association, membership is voluntary but the companies who choose to become members agree to abide by the ITSPA code of practice.

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.
