The present invention provides an effective and efficient way to link multimedia sessions involving multimedia clients with a conference call involving telephony devices associated with the multimedia clients. In operation, the telephony system will recognize a call directed to an audio bridge, as well as trigger a message indicating the same. The message includes the telephony device's directory number, which is used to access an address for an associated multimedia client. The address for the multimedia client is sent to a multimedia bridge, which is associated with the audio bridge. The multimedia bridge will use the multimedia client's address to send the multimedia client the address for the multimedia bridge, addresses for other participating multimedia clients, and various types of information bearing on the multimedia aspect of the conference call.
