Treo 600- Calendar phone number dialing?

I have the new Treo 600- great device.

I want the ability to dial a phone number or go to a URL entered into the text of a calendar entry. For instance, I have a calendar entry for 3 pm today. It has a phone number in it to call for a conference call. I want to be able to scroll to the number and push the center button to have it dialed. Snappermail works exactly this way now.

Anybody know of an app that can do this- maybe a cal replacement?

That would be an AWESOME FEATURE. I'm not aware of one.

I'm looking for the same thing on a Treo 700. I can't believe it's not there! Blackberry users have it. My old samsung i-600 does it. I've been searching for software that supports it, no luck....
