Description
Determines the speeds that will be used for calls from this
system when:
 The Call Quality selection is either unavailable or set to
Auto on the Place a Call screen.

The call is placed from the directory.
If the far-site system does not support the selected speed, the
system automatically negotiates a lower speed.
Allows you to restrict the bandwidth used when receiving calls.
If the far site attempts to call the system at a higher speed than
selected here, the call is re-negotiated at the speed specified in
this field.
Select to go to the Call Speeds screen and specify the call speeds to
make available to users, if you are allowing them to choose speeds on a
call-by-call basis.
