I switched our company (~20 users) over to www.onsip.com for phones... I'm using all Polycom hardware... works great if you have good bandwidth. All setup and config is web-based and they auto configure the Polycom phones (335's and 550's). Onsip works with ekiga and there's sip clients for iOS and Android that work OK.

Google Apps for everything else!
