— Meet-Me Conference (MMC) is an alternative to the standard conference call whereby users must first call another party to add (or “pull”) them into the conference. With MMC, users can dial in to join the conference on their own accord.
Besides how the conference is formed, MMC behaves much like a standard conference. The notable distinction between the two types of conferences is the number of parties it takes to create them. A standard conference requires at least three parties. A MMC is created once the first party joins and is not terminated until the last member leaves. A standard conference ends when there are fewer than three parties remaining.
