Call conferencing allows more than three people to converse at a time. Technically, conference calling has two definitions:
I(4);C(0);CR(0);R($0) With most VoIP providers, call conferencing means expanded 3-way calling. Dedicated Call Conferencing providers may be VoIP providers or they may not be.
Just like a 3-way call. Call users until everyone you need can join. The maximum number of users varies between providers.
