A call processing system and method are based on a dual mode terminal. The call processing system comprises: a Private Branch Exchange (PBX) which, when a call is incoming to an extension through a first network, checks registration information based on a link test message transmitted periodically from a destination terminal having a number of the extension to which the call is incoming, and processes the incoming call in real time; and a dual mode terminal which is interconnected to an extension of the PBX, operates in at least one of a Wireless Local Area Network (WLAN) mode and a wireless communication mode, and processes the incoming call.
