Change call_flow_sound_on to call_flow_sound. Call flow anti to alternate and call_flow_sound_off to call_flow_alternate_sound.
This changes make it more consistent with the front end. For the few developers that have the call_flow_sound_on and call_flow_sound off I offer the these alter table statements.
ALTER TABLE v_call_flows RENAME COLUMN call_flow_sound_on to call_flow_sound;
ALTER TABLE v_call_flows RENAME COLUMN call_flow_sound_off to call_flow_alternate_sound;
