2. Go to System > Admin Settings > Network > Call Preference and select
Enable ISDN Gateway.

system when:
• Call Quality is set to Auto on the home screen and

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.
