How to do Conference Calling on 3CX

What is 3CX Call Conferencing?

Call conferencing lets you bring multiple parties into one call so everyone can talk together. In 3CX v20 you can:

‍

• Convert an existing active call into a conference and add further participants.

• Schedule a conference (via “Meet”) in advance and invite participants by link or dial-in.

• Use desk-phones, web/desktop clients or mobile apps to participate.
