Thanks for the feedback. On my BlackJackII Windows Mobile 6.1 device from within a meeting invitation, I can click on the contact and call and I can also click on the conference call number from meeting "location" and dial directly into the meeting from my device. I'm running Outlook on my device. Let us know if you need more information or would like to further discuss. This thread stays open for viewing and additional comments even though I'm marking this as answered for our team's tracking purposes.
Thank you from the Microsoft Windows Mobile Team
