A method of switching a call to a multipoint conference call includes sending a message (201) from a first terminal (105-T1) to a gatekeeper (102) which provides address translation and control access to a shared network medium (101). The call is initially established as a point to point communication between first terminal (101) and a second terminal (105-TN) over shared network medium (101) while complying with H.323 standard. Message (201) contains a request for the multipoint conference call. The method furthermore includes selecting a multipoint control unit (104) connected to shared network medium (101) to allocate resources for the multipoint conference call, and then switching the call to the multipoint conference call via the allocated resources. Thereby, the initial call is switched to a multipoint conference call without interrupting the initial call.
