I do it for my job all the time. It's super important to be good on the phone in what I do.
Just always think about why you're calling before you call the GP for example.
Hi, my name is Joan Rivers, I'm calling to book an appointment with the doctor today.
Hi, this is Joan Rivers calling. I am calling to find out when the bin collection days are for my borough. Are you the right person to speak to ? Or would you kindly help me get to the right place ?
Hi, it's Amelia calling. I'm very interested in understanding how your services work. Who is the right person to speak to about this ?
These are random ones that popped to mind.
But if you always do:
Intro
Why you're calling
You can't go wrong and it starts the call off really well and then it just flows. Try to be as succinct as possible. Before you pick up the phone, really have a think about what you need to get from the call and then try to say it in the simplest way for the other person to understand.
I'm quite good at it now, but hear others all the time and they just haven't really thought about how to best phrase why they're calling. They then stutter and lose it and it becomes difficult to recover. If you start off right, it really helps.
