PCTEL, Inc. is expanding the capabilities for its Roaming Client-VE (Voice Enabled) software, providing Voice Call Continuity (VCC) based on the emerging 3GPP standard and support for Microsoft Windows Mobile 5.0.

The PCTEL Roaming Client-VE delivers an IP Multimedia Subsystem (IMS)-compliant core engine, facilitating portability to other operating systems and enhancing integration of third-party applications through a published API. These new capabilities along with other enterprise features, such as four digit dialing, address the growing need for service providers to deliver seamless fixed and mobile call connectivity between disparate networks and provide a framework for third-party IMS application developers.

PCTEL's Roaming Client-VE is an IMS-ready software client enabling ubiquitous communications over both Wi-Fi and traditional cellular networks. Designed for dual-mode handset devices and interoperable with major IMS-infrastructure vendors, the Roaming Client-VE allows service providers and cable operators to deliver true mobility to their end users.

Using PCTEL's Roaming Client-VE, users can make and receive calls, on Wi-Fi or cellular networks, through a single user interface on their mobile device. Combined with VCC capabilities, users can move from Wi-Fi to cellular coverage and vice-versa without dropping the call. The calls are seamlessly handed over based on the best network connectivity available to the device and/or user preference.

PCTEL will be demonstrating its Roaming Client-VE at the 3GSM World Congress 2006 in Barcelona, Spain.
