A management apparatus by which one of facsimile apparatuses that externally receives facsimile data is selected based on current power modes of the facsimile apparatuses. Facsimile data can be transmitted from any of a FAX and MFPs on an IP communication network. One of MFPs which are not in a power saving mode is selected by the management apparatus, and a URI of the selected MFP is registered in an SIP server. When facsimile data whose original transmission destination is an MFP which is in a power saving mode is transmitted, the facsimile data is transferred to and alternatively received by the selected MFP.
