Using Outlook as a example, an easy to use system allows me to send a standard Meeting Notice (or Email) to my participants without having to remember phone numbers, passcodes, urls, etc. When my reminder pops, I open my appointment and monitor status of the call. At the appropriate time I click a button and start the web conference and get a call back from the audio bridge. I can dial out to participants from my Contacts list in Outlook (Wow, one list to maintain!!). After the call I can add participants to my Contact list. All without leaving Outlook.

In the interest of full disclosure I must tell you that this is what we do at JCS Technologies. We have offered an Outlook addin since 2004 and are currently involved with serveral CSPs to fully integrate their products into Outlook.
