The visual voice mail technology enables iPhone users to check all incoming voice messages in an e-mail-format, with the option of designating the order of playing back the messages.

The company had sought $360m in damages and future royalties when it filed the lawsuit. Both Apple and AT&T have agreed to take out licenses on the technology, joining eBay’s Skype division, which last month settled a lawsuit filed by the company. Financial terms of the settlement were not disclosed.

Last December, the company had sued Comcast, Cablevision and eBay over the same technology and sought damages and royalties amounting to $300m.

The company has licensed its technology to Time Warner’s AOL, VoIP network provider Vonage Holdings, Sprint Nextel and GotVoice.
