Service for audio meetings - what?

Question

Project management

Hello!
There is a number of users 10-30 scattered in different cities. Periodically, you need to hold conference calls with them (only audio is enough).
Advise, preferably free, a service so that all listeners can "speak" in front of their colleagues in turn.
I really wanted a bi service that works in the browser and does not require a client....
