3CXPhone for iPhone has won the Voxie Best iOS VoIP App 2011 Award out of a whole host of VoIP based apps from within the Apple App Store.

“Few apps are as powerful as 3CXPhone for iPhone. If your office is using the terrific 3CX Windows-based PBX, then putting this app on your iPhone is a no-brainer. Connect your phone to the same LAN the PBX is on, and 3CXPhone is provisioned automatically for you. But even if you’re on a different PBX (Asterisk, for example), 3CXPhone works just as well.” – Voxilla.com
