The telephone companies promoting voicemail conclude that voicemail will soon make answering machines obsolete. This prediction is supported by the observation that voicemail is more convenient, more flexible, and less expensive than answering machines.
The telephone companies are assuming that there are not reasons other than convenience, flexibility, and cost that determine whether consumers use voicemail or answering machines. It could be true that voicemail is superior in convenience, flexibility, and cost, but users still prefer answering machines for some other reason. This would weaken the support for the conclusion that answering machines will soon be obsolete.
