Voice over Internet Protocol use continues to gain subscribers in the home telephone service market, according to San Francisco-based Telephia, a provider of performance measurement information to the converging communications and mobile industries.

Households subscribing to pure-play subscription VoIP services--meaning those who are either replacing or complementing existing traditional landline service--rose from 2.2 million in the first quarter of 2006 to 2.9 million in the second quarter, according to the survey.
