Can ZRTP be used in conference calls?

Yes. Most conference calls are connected via a conference call mixer or a PBX, connected in a star topology. Think of the conference call mixer as the hub of a spoked wheel, with each spoke connected to a party in the conference call. Each spoke is a separate ZRTP connection, with its own separate session key. The conference call mixer acts as a trusted man-in-the-middle (MiTM) between ZRTP-equipped phones, and performs the audio mixing for the conference call.
