How to get off the phone quickly
Explain it isn't a great time.
You're busy with a project, have a deadline and you're trying to get a certain task done, etc. Ask if they can call you back and give them a better time.
Available choices:
[1]. Talkers sometimes don't understand subtle hints so it's alright to insist you get back to them later. Starting chatter with them only makes it harder to get off the phone.;
[2]. Using an apologetic tone, ask them why they call you. They might have extra work to do or might need a bit of a heads up in the middle of that call.;
[3]. Yes; there's a reason you probably need to do your most important tasks early; but you can also occupy your mind with other things without involving the person who is calling you on the phone. A great way to gently redirect the call is by saying it is urgent and you're stuck for 10 minutes.;
[4]. Say that whatever the time is, you'll call back again, within 24 hours. Alternatively, you could text them again, but explain that you have to be somewhere, so just ignore them.;
