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
Included for compatibility. No functionality.
