Are these two verbs different in any way

[leogetsky]

電話をかける
電話する

Is there any difference? How to know when to use either of them?

Thanks!

From what I can find:
電話をかける - to make a phone call
電話する - to be on the phone

It’s a small difference, but basically just the difference about starting an action vs. being in the middle of an action.

For example if you want to say that you are currently on the phone, you would use 電話する. If you want someone to call you, you would use 電話をかける.
