The Upshot
 DiVitas Networks promises seamless voice mobility between cellular and Wi-Fi networks, giving employees one phone number and voicemail box. Road warriors get a Wi-Fi alternative in hotspots and home offices, while corridor warriors get full access to PBX services.  Enterprise solutions from Avaya, Cisco, FirstHand Technologies and OnRelay focus on fixed mobile, moving from PBX desk set to mobile phone and back. But these products require a specific handset, wireless carrier, PBX or Wi-Fi infrastructure. Carrier-centric solutions such as Embarq's Smart Connect don't offer the control over voice services that the PBX provides.  Vo-Fi to Vo-Fi works very well, but the solution is hamstrung by handset issues, short battery life and cellular data service that's not pervasively 3G. Lack of integration with enterprise directory stores, feature-lite PBX options and an unreliable IM service indicate that it's not enterprise-ready.

Your employees are walking telephony hubs, with desk phones, cell phones and even softphones. But they've also got multiple phone numbers and voicemail systems, and colleagues and customers may be playing phone tag instead of doing business.
One attractive solution is mobile-to-mobile convergence (MMC), in which dual-mode phones integrate Wi-Fi and cellular services to give companies inexpensive, truly mobile voice. DiVitas Networks' MCA (Mobile Convergence Appliance) and MCC (Mobile Convergence Client) are the first products to attempt vendor-agnostic, single-number access and seamless mobility between cellular and Wi-Fi networks using a single handset.
Unfortunately, DiVitas is constrained by the third-party products, technologies and interfaces sold by vendors that may not want to see DiVitas succeed. The first release suffers from limitations in the handsets' APIs and shortened battery life. Plus, seamless roaming is only possible in those areas with advanced 3G services. It also doesn't integrate with enterprise directories.
