Reference excerpt

PhoneValet Message Center (or, simply, PhoneValet) is a discontinued Mac-based multi-line computer-telephony software application from Parliant Corporation. The application provided computer-telephony functionality including voicemail, call recording, and the maintenance of a call history. The system is a combination of software and hardware. PhoneValet was awarded an Eddy award (Macworld Magazine's editors choice award) for 2006.

History PhoneValet was initially released on July 23, 2003 as a system to maintain a list of inbound and outbound calls, including telephone numbers, start and end times and notes. The system also enabled pop-up announcements of incoming callers based on Caller ID, and a spoken announcement of this and ancillary information drawn from a user-maintained address book. Additional functionality included dialing with automatic determination of long distance and calling card codes. This initial version did not allow the telephone to be answered as the hardware device provided could not take the line off-hook. On June 30, 2004, Parliant released version 2.0 of PhoneValet, now with the Message Center moniker. This version shipped with a revised hardware device (the same one shipping today) designed to allow the computer to answer the telephone. The 2.0 product integrated voice mail messages into the 1.0 product's call history system. The new device also supported automatic gain control, providing the ability to make high-quality audio recordings of both sides of telephone calls. The manufacturer made several further releases within the 2.0 rubric, adding the ability to dial in to check for messages, information center features and real-time voicemail audio screening. On July 11, 2005, Message Center 3.0 was released. Along with this update, Parliant released two large PhoneValet extensions: PhoneValet Anywhere and PhoneValet PodCast. PhoneValet Anywhere allowed users to manage the core functions of the PhoneValet Message Center over the internet through a new web interface. PhoneValet PodCast was more of a tool-suite designed to help PodCast makers record and edit phone conversations, including a background sound scrubbing tool and a stereo audio editor with a DSP. The core Message Center 3.0 update added ring-tones, call blocking, and individualized greetings tied to specific callers. The 4.0 version March 17, 2006 was a free upgrade adding automatic recording of all calls on the line (prior to this time call recording was activated manually by the user). On November 20, 2006 Parliant released version 5.0 with automated attendant features and unlimited-depth call trees. Automated attendant functions allowed a caller to specify the person, department or extension they wish to be transferred to. The application accomplished this on a single line by paging the person or department through the computer's speakers, playing hold music to the caller in the meantime. If the call went unanswered the caller was directed to a voice mailbox or to make further selections. The product was discontinued in May 2011, with continued technical support until June 2012.

Worked examples

Example 1 — a first encounter with PhoneValet Message Center

Start with the simplest possible case. Write down what PhoneValet Message Center claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to PhoneValet Message Center before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about PhoneValet Message Center ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of PhoneValet Message Center

In research: PhoneValet Message Center appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses PhoneValet Message Center in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: PhoneValet Message Center is common in secondary-school and first-year university syllabi. It links to neighbouring topics MacOS multimedia software, Telephony software, so understanding it makes those chapters shorter.
In everyday life: Look for PhoneValet Message Center outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
