Another apps that got update is Ring Ring Ring, this is an application that allow you to use your iPhone address book, click to dial using your IP phone. So it reduces the hassle to sync your iPhone contact list with your UCM personal directory. You simply use your iPhone contact list as your personal directory.
I haven't made much change to this app, for sure you can give me idea what feature should I add. Basically I have just optimise it for the 4-inch Retina display.
You can get the entry from your address book by clicking the address book icon on the right. Then the contact will show up.
Simply click on the phone number, then it will ask your IP phone to make phone calls.
Alternatively you can use the number pad instead of phone book entry to make calls.
