Dont miss the call in the first place (easier said than done) Have your business line forwarded to the cell phone. When it rings answer it. If you do happen to miss it call them back and apologize for missing their call and ask what you can do for them. Lots of people complain to me about not getting call backs, so why not surprise them and call them back without a message. I think the people that do not leave messages are the ones that have left messages at 20 places in the past week and if anyone and I mean anyone would call them back they would have the job.
