Two Call Support
(in Web UI)
Description	Enables or disables the single media path restriction between the
	57i CT base unit and the handset.
	When this feature is enabled (set to 1), you can make separate active
	calls from the 57i CT base unit and from the cordless handset. If this
	feature is disabled (set to 0), only one call can be active at a time either
	from the base unit or from the handset.
	When this feature is disabled, and you make an active call on either the
	base unit or the handset, any other attempt to make an active call is put
	on hold. Also, when this feature is disabled, more than one call can
	negotiate complex audio codecs since only a single call is decoding
	audio at a time.
