I recently migrated my beloved PhoneValet installation to a new (but old) Mac mini. In the process, my Alfred scripts for remote dialing stopped working. After much troubleshooting, I determined that I had to turn on Personal Web Sharing (on the mini) for that feature to work. This is (sort of) documented in the PhoneValet docs, which surprisingly are still online despite it being abandonware, but this requirement isn't explicit. So, for anyone else having this problem, here's hoping you'll find this note.
