Vo-Fi Awareness (December 2005): The first phase of the plan, bringing voice-aware WLAN features to Aruba mobility controllers, was completed in December 2005. (See press release, "Aruba Announces Mobile Voice Over IP Enhancements to the Enterprise Mobile Edge") These features were enabled by the Aruba mobility controller's integrated stateful firewall and application-aware adaptive radio management.

Vo-Fi Scalability (November 2006): Phase two brings new capabilities for scalability, performance and reliability features based on the IEEE 802.11e standard. The new features being announced today (See companion release, "Aruba Networks Turns Up the Volume on Vo-Fi") include WMM, TSpec, WMM-PS, and additional enhancements.

Enterprise Integration (1st half 2007): In the third phase, Aruba will add the WLAN/cellular network call handover function to its existing mobility controllers. This function will be explicitly designed to augment and scale the handover function being planned by IP-PBX vendors, and an open application programming interface (API) will provide the integration hooks necessary for easy integration. The API will also deliver greater visibility into VoIP calls made over the mobile LAN, enabling IP-PBX vendors to inject mobile LAN awareness into their existing VoIP management systems. Phase three will also include the release of a client behavior specification designed to help mobile handset manufacturers deliver faster handoffs both within the WLAN and between cellular and Wi-Fi.

Carrier Integration (2nd half 2007): Phase four will augment carrier FMC architectures based on the Unlicensed Mobile Access (UMA) standard with managed WLAN and security services.

Seamless Networks (2008): The fifth phase will focus on delivering seamless interworking across enterprise-based IP multimedia services and carrier-based IP multimedia services and will rely on the IP Multimedia Subsystem (IMS) architecture being standardized in the 3GPP standards body.
