Android's latest version of Android (4.1.x-4.3.x), code name Jelly Bean, comes pre-loaded on all manufacturer flagship devices. ISC recommends purchasing devices that come with the latest version of Android, as it offers significant speed and UX improvements. More information on the latest version of Jelly Bean can be found on the Android website.
"Nexus" devices with stock Android generally obey Exchange ActiveSync security policies and remote wipe commands. Devices with UI overlays do not respond to EAS policies in a predictable manner. Android 2.x doesn't support encryption at the platform level, and all data on the device can be accessed via USB if it is lost or stolen. Android 3.x and later devices support disk encryption, but this encryption only prevents data on the device from being accessed if the device has been turned off. When turned on, all data on the device can be accessed via USB if it is lost or stolen.
Android devices are ActiveSync capable. Email, contact syncing, and calendaring are present and work with most common features via Exchange ActiveSync. Folders are browsable, and conversations can be grouped by threads.
Divide is an alternative Exchange ActiveSync client for Android that combines a reliable EAS environment with a consistent interface and robust security. Combined with a VPN, Divide provides levels of security similar to that of a BlackBerry connecting via a BES. The Divide client is free. Please see ISC's Divide product page for more information.
XpressConnect, via AirPennNet-Help, works for most devices.
PennNet Phone voicemail attachments
Most Android devices cannot play back VOIP voicemail received on the device via email. ISC is looking into third-party utilities that may permit playback.
