However, if the call is made throughan LCOT/CLCOT or T1 [LCOT/GCOT] card, the caller hears aringback tone.Intercept Routing—DND If a called party is in DND mode, the call is redirected to thepreprogrammed destination.Intercept destinations can be assigned to extension ports.® [604] Extension Intercept DestinationWhen the original destination is: The Available Intercept Destination is:• Wired Extension (PT/SLT/T1-OPX)• PSThe destination assigned to the original extension.® [604] Extension Intercept Destination• ICD Group The ICD Group Overflow destination assigned to thegroup. (® 1.2.2.6 Overflow Feature)® [625] Destination for Overflow Time Expiration• VM Group (DTMF/DPT) The destination assigned to the first extension of theVM group.• DISA*1 If all DISA ports are busy when a call is made usingDISA, one of the following can be selected throughsystem programming:• Disable: Busy tone is sent to the caller.
