8.7. AHCP -- Enable or Disable Call Progress Based Auto 
Hangup
This command sets or queries the status of the call progress based auto hangup feature. There are two 
methods of auto hangup supported: call progress and loop drop. The call progress method listens for 
off-hook or busy tones and hangs up the phone if they are detected. The loop drop method looks for a 
drop in loop current on the phone line and hangs up the phone if a loop current drop is detected. The 
AHCP command controls the call progress auto hangup feature. The 
AHLD command controls the loop 
drop auto hangup feature. These two features are controlled and implemented independently. 
This command is a boolean command. See 
Section 6.1 for more information on this type of command. 
This command is saved to non-volatile memory only as part of a preset. The state of this command will 
be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
