I have a MBA and iMac, both running Lion. I also have iPhone 4. I have different email's setup for the notification for all 3. I'm able to call from MBA and iMac to each other, and to the iPhone. Here's my issue: When I try to originate a call from the iPhone to either the MBA or iMac, I get a "call failed". Am I supposed to be able to do this? Thanks for your help!
