I am a long time 3CX user - I administer it at work. Working on a voice project for my church, and naturally want to use 3CX because I find it easy to administer. However, we don't use the conferencing at work, so I am not familiar with it in 3CX. The church uses another, external service that allows members to call a phone number and then enter a PIN to be connected to the audio feed from the church's mixer board. That same concept is what we want, but - this is where I am not sure about the 3CX world - is this how the conferencing feature works in 3CX? And is this included in the free 2call edition? Can the PIN be the same for all callers (as many are elderly and don't have email in order to receive an emailed PIN). Is there any limit to how many callers can call in to connect to the conference call? I appreciate any input. Thanks.
