Coordinate with an office assistant to find a new time for a phone meeting when your contact is unavailable.
Hello, this is Sarah from the marketing department. I'm calling because Mr. Henderson is actually tied up in a meeting right now and won't be able to take your call.
Oh, I see. Thank you for letting me know. Is there a better time to reach him later today?
He should be free later this afternoon. I have an opening at 2:00 PM or another one at 4:30 PM. Do either of those work for you?
I have another appointment at 2:00, so the 4:30 PM slot would be much better for me.
That works perfectly. I'll put you on his calendar for 4:30. Should he call you back at this same number?
Yes, this number is fine. Will he be calling me directly, or should I call the office again?
He will call you directly. I've made a note of it, so you can expect a ring around then.
Great, thank you for your help. I'll wait for his call at 4:30.
