Methods and apparatus are described for receiving a fax transmission at a mobile phone. In one embodiment, the mobile phone receives an incoming call and answers the incoming call, upon receiving a command from a user of the mobile phone to answer the incoming call. A program on the mobile phone then detects that the incoming call is a fax transmission, and then places an outgoing call to a fax server. The program on the mobile phone then conferences the incoming call with the outgoing call to the fax server, such that the fax server receives the fax transmission. Other embodiments are also described and claimed.

The present invention provides a technique that enables an image communication apparatus capable of performing voice communication and T.30 in-band FAX communication over the IP network to positively detect a CNG signal and achieve switching to FAX reception in the answerphone connection mode and the FAX/TEL-switching mode. The communication apparatus includes a MODEM that controls facsimile communication and a SLIC that controls a telephone. A selector includes switches for connecting the IP network and the MODEM, and switches for connecting the IP network and the SLIC. A CPU controls the switches of the selector such that signals from the IP network are supplied to both of the MODEM and the SLIC.
