But landline phones are not just a problem because they no longer represent the best way to get in touch with somebody: they cost every business money, and they provide a frustrating channel of communication the checking of which wastes time. While some users like the idea of a work phone and personal phone, a host of technologies exist that can route calls to a mobile phone and can easily be used to automatically send them to a voicemail outside of office hours. For my money, the best voicemail greeting says “Don’t leave a message; email me.” And if a worker’s job requires only a phone, they should arguably be working from home anyway.
