Description
Enables or disables the single media path restriction between the 
480i CT base unit and the handset.
When this feature is enabled (set to 1), you can make separate active 
calls from the 480i 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.
