The CompactSIP SDK features source code running on a Pocket PC ARM emulator, Telesoft says. The SDK makes use of SIP (session Internet protocol) communication standards, through which telephony "becomes another web application, making it easy to build email, instant messaging, e-commerce, video, multimedia, navigation, soft-phone, and other broadband Internet applications" into a wide range of embedded and mobile devices.

Telesoft claims CompactSIP is "the industry's leanest SIP stack," with a memory footprint as small as 63KB, making it ideal for resource-constrained handheld and embedded applications. In addition to supporting Windows Mobile 5.0- and Windows CE-based designs, the SDK also targets Linux, VxWorks, and other popular embedded software platforms.

The company says its SIP stack has shipped for over three years, during which time the stack has proven its compliance with industry standards and its utility in real-world applications. In particular, the software has been used within WiFi phones, media chips, gateways, set-top boxes, ATAs that turn traditional telephones into IP devices, and IP phones, according to Telesoft.

TeleSoft will demonstrate the Compact SIP SDK in its booth at CTIA Wireless 2007 in Orlando, Florida later this month.
