Answering machines and voicemail allowed for screening calls. That's why they started IAs from the CP on the last leg of a trip. There was no escape unless you were on the M88 and did the superman in the aft lav and went out the stairs. I think we should just eliminate them and make everything a GS proffer and make crew scheduling plan ahead. they get 2 days out coverage now and last minute can be fedex style once through the list 200%, twice through the liset 300% etc.
