Voice communications company Voxeo announced this evening that it will launch a developer platform for SMS, IM, and voice called SMSified at the end of the week. Developers can create apps for free and will be charged 1 cent per text message sent, making the service cheaper than Clickatell and more versatile than Twilio.

Voxeo CEO Jonathan Taylor said that a major mobile carrier is currently implementing the platform across its own network, although further details about the partnership are not being released at this time.

The news comes more than a year after Voxeo began its buying spree, adding web conferencing startups and mobile web technology to its portfolio of acquisitions, along with the instant messaging API company IMified. With the launch of SMSified, it seems likely that Voxeo will continue its move away from the more traditional telephony operations that have been its bread and butter for the past decade.

A Voxeo spokesman said in an email that the API developer space currently brings the company more than $50 million in annual revenue.

More details are forthcoming and will be posted as we get additional information.
