4.6 AT*E2PHFB Portable Handsfree Button Sense Enable
This command allows the user to set the functionality for a PHF
(portable handsfree) button, as used on simple handsfree equipment.
When set to ON, the MS will detect the shortcircuit of the ATMS and
AFMS lines, and interpret this as a PHF button press. This has the effect
of answering/hanging up a call without recourse to AT commands.
4.7 AT*ELAM Ericsson Local Audio Mode
Used to route the microphone and/or the loudspeaker signal to the
system bus. This function is used when the audio information is to be
communicated over the system bus rather than the GSM radio. This
functionality can be used by an MC link accessory that communicates
with a PSTN adapter.
