The present invention relates to a modem that allows the user to switch back and forth between voice and data telecommunications during the same phone call without redialing. Such switching back and forth between voice and data telecommunications is accomplished by lifting the telephone handset for voice communications and replacing the telephone handset for resumption of data communications. The present invention also allows a local user to communicate with a remote user via a speaker at the remote modem location without the remote user picking up the remote handset.
