I'm setting up a 3CX PBX on Amazon Lightsail, and I'm having trouble with setting up conference calling that will allow external participants to dial in (like FreeConferenceCall.com, or other similar services).
I have my inbound and outbound calls working, so I assume my basic setup is okay. I have one number I purchased from Skyetel (the VOIP provider I'm using), and I have another number that's being ported in from Skype (not yet active on Skyetel).
However, I'm not sure how to properly setup conference calling on 3CX. I have a single extension (00), and I have all of my trunks (inbound and outbound) set with the "Trunk" value of *1949 (the last 4 digits of the number I purchased from Skyetel).
In Settings >> General >> Conference, I set my Conference Extension to 00 (the only one I have), and I've set my External Number to the number I purchased from Skyetel (the one ending in 1949).
Are there other settings I need to host conference calls?
