As a Platinum Partner, SIPquest is extending personalized control of communications services through Fixed Mobile Convergence (FMC) and IP Multimedia Subsystem (IMS) solutions over Wi-Fi, GSM, and CDMA network interfaces to the Symbian OS ecosystem. Symbian develops and licenses Symbian OS, the open operating system that powers today's most popular smartphones. Symbian OS is licensed by the world's leading mobile phone manufacturers and, to date, almost 48 million phones based on Symbian OS have shipped worldwide.

Today, the SIPquest Mobile Assistant works with Symbian OS phones to deliver instant messaging, presence and corporate directory services to IP PBX users.

According to David Hattey, president and CEO of SIPquest, "As a member of the Symbian Platinum Program, SIPquest is delighted to work with Symbian to bring functionally rich VoIP solutions to Symbian OS phones and thereby satisfy the needs of users that depend on dual mode-WiFi and GSM or WiFi and CDMA-features."

Symbian OS phones are growing in popularity worldwide. As of Q3 2005, Symbian OS phone shipments grew more than 131% compared to the same quarter last year. According to technology analyst firm Canalys, overall global shipments of smartphones are up 183% year-on-year in Q3 2005 with Symbian emerging as the market leader.
