Internet phone service Vonage said on Friday it has settled a patent dispute with AT&T.
Vonage was hit by a string of patent suits since going public in May 2006. It settled a suit with Sprint Nextel and another one with Verizon Communications in October.
AT&T sued the company, accusing it of using packet-based telephony products, which allow voice conversations to be carried over the Internet, based on products that use technology covered by AT&T patents.
Vonage did not disclose the nature of the settlement, which it said occurred on November 7. The settlement was finalized on Friday.
