Just read about a new conference calling system that saves you the hassle of remembering call-in numbers and pins. This one calls you AND your participants and is called Bridg.me.
It is free but probably won't stay that way for long. They are still ironing out the kinks and it currently only works with Google Calendar. I know a lot of you use that for scheduling so thought it might be of interest. It might also be a great option for some of your clients.
Here are a couple of links to articles about the service:

Would love to hear feedback from anyone who actually tries it out!
