Fujitsu
F80P-172 (aka PCX)

When this phone was introduced in December 1992, Fujitsu claimed it was the smallest handheld flip phone with a built-in “answer chip”. It provided a unique capability that when a user was unable to answer their phone, “a built-in simple pager with voice chip” could answer incoming calls and record the phone number of the person calling. Fujitsu believed this would be perfect for business users who could turn off the phone's ringer when they were in a meeting and select the answering function to record the phone number of the person who had called. The voice chip was able to make an announcement to the person calling to let them know the person they were trying to reach was unable to take the call. It then instructed the caller to key in their phone number so it could be recorded for later use. This “pager feature” could record up to five phone numbers. The PCX also offered “one-touch answering”, even when the flip was closed. PCX users could answer the phone by simply pressing one of the volume control buttons located on the side of the telephone. The PCX was also the first cellular phone to allow the use of three different types of batteries “within a single battery cartridge, providing flexible power options when travelling”. When it was launched the phone retailed at $1,295.
