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.

Setting Up

Creating or joining a MMC requires credentials consisting of up to three pieces of information: a Meet-Me Conference Access Number, a Bridge Number, and a PIN. MMC should not be considered an impromptu (or unplanned) conferencing facility. It is expected that the organizer of the conference will provide conference participants with the MMC credentials prior to the conference, either by e-mail or some other means.

MMC Access Number

8888 - For internal users, this is like dialing a feature access code to activate a particular feature. 

MMC Bridge Number

Bridge numbers are NOT configured on the system. They are usually the conference organizer's own DN but any number can be used if it resolves to a dialable DN within the network. Valid bridge numbers are 1-7 digits in length and can contain digits 0-9 plus *.


The PIN is optional. You can use it to add an extra level of security and differentiation from other Meet-Me Conferences. PINs are NOT configured on the system nor validated. They can be 0 to 10 digits in length; * and # are not allowed.

The following are examples of MMC dial strings, one with a PIN and one without (both use the End of Dial character, #):

88881126#1234# (with PIN)

88881126## (no PIN)


  • The combination of the Bridge Number and PIN is used to uniquely identify an MMC. The system creates an MMC if the Bridge Number/PIN combination dialed by a user is not currently in use. If the combination equates to an active MMC, the user will be added to that MMC.

  • The concept of a conference leader or host does not apply to MCC. No single participant “controls” the MMC, including the conference organizer or the party who first dials the Bridge/PIN combination to create the MCC.

Callers can dial in to a conference directly or ask the console operator to transfer them. The operator would then dial the bridge number and PIN (if required) to join the conference and then release the call to complete the transfer. A user may also transfer a party into a conference that they have entered on behalf of a held party.

Feature Interactions 

  • Each MMC has a limit of 8 participants.

  • A single system can support up to 200 simultaneous MMCs.

  • MMC does not support Silent Monitoring.

  • A Meet-Me Conference cannot be split (no Split softkey is presented).

  • AN MMC Access Number cannot be a call rerouting or call forwarding destination.

  • Speedcalls can be used to direct calls to an MMC bridge. The speedcall must contain the MMC access number and bridge number. The PIN is optional; if omitted from the speedcall but included in the conference invitation, the caller will have to dial it. The table below shows valid speedcalls for the following MMC dial string:

    • MMC access number: 8888
    • Bridge number: 2000
    • PIN: 1234

Using SpeedCall Keys

SpeedCall Digits





Caller receives dial tone and must dial the bridge number and PIN to enter the conference.



Caller enters bridge for 2000 with a PIN of 1234.



Caller enters bridge with a PIN of 1234. The terminating # is not necessary but can be handled.


Valid but probably not desired

Enters bridge for 2000 with a blank PIN (because digits after the initial # are ignored)



Enters bridge for 2000 with a blank PIN.



Enters bridge for 2000 with a blank PIN.



Pauses (P) are not allowed in Meet-Me Conference dial strings.

Note that all digits in a speedcall after a pound (#) are ignored.
