Common Speed dial between offices on Aastra 6731i

I have a number of Aastra 6731i phones. Unfortunately, the systems are not Freepbx Is there a way to “share” a common speed dial list using XML pages? The pages could be hosted on a local server. I would like to see the ability to scroll through the numbers and then dial with a minimum of effort on the users part. Can this be done??

Thanks
