Answering machines are much less expensive than voice mail systems or answering services. In addition, as answering machine technology has improved, these machines have become much more flexible at handling large volumes of messages or multiple users. There are four different types of answering machines currently on the market. The least expensive answering machine models use a single tape for both incoming and outgoing messages. The problem with this approach is that callers must wait a long time before recording if the answering machine tape is filled with other messages. More sophisticated answering machines use two tapes, one for incoming and one for outgoing calls. This minimizes the delay before recording, since the incoming message tape is kept wound to the appropriate place. Newer answering machines often use digital chips to record incoming or outgoing messages. These answering machine models typically combine a digital chip for the outgoing message with tape for incoming messages. Purely digital answering machines use no tape at all, recording both incoming and outgoing messages digitally.
Two-line answering machines, while relatively uncommon, are available for businesses that receive calls over more than one line. However, most two-line answering machines are fairly limited in terms of capabilities. For example, many of these answering machines cannot pick up a call on the second line while simultaneously answering a call on the first.
The biggest difference between digital and analog tape answering machines concerns storage flexibility. Unlike a tape recorder, digital answering machines can erase one message without disturbing others on the answering machine. This allows important messages to be kept without cluttering the answering machine with less relevant messages. A second advantage of digital answering machines is that sound quality can be better than with tape devices. Tape answering machines all suffer from some level of background hiss, particularly with the outgoing message, while digital answering machines typically offer a much cleaner-sounding message. However, be aware that digital technology does not guarantee good sound. Some digital answering machines use cheap microphones or very low sampling rates. In many cases, a cheap digital answering machine may sound worse than a tape answering machine. A third advantage of digital answering machines is reliability. Since these answering machines have no moving parts, they tend to be very sturdy. In contrast, tape-based answering machines are relatively complex, and tend to break down after a few years of use. One disadvantage of digital answering machines concerns power failure. If the power goes out, digital answering machines can lose all their messages unless there is a battery backup feature. Other answering machine features. To keep track of when messages arrive, most firms find it very useful to have a answering machine that offers a time and date stamp. This records information about the time of the call before the start of each message. Many businesses need different messages for different times of the day. Answering machines equipped with a multiple greeting feature can easily handle this requirement. In most cases, you record multiple greetings, and then set specific times when each answering machine message should be played. Some answering machines offer multiple mailboxes that allow callers to route messages to a specific recipient. The caller simply enters a touch tone code and records the message in a specific mailbox. When people return to the office, they can play just the answering machine messages left in their mailbox. For those who do not wish to handle individual messages, an announce-only feature allows a recorded message to be left without giving callers the option to record a response. One important specification to check with any answering machine is its recording time. Many units limit either the length of individual messages or the total amount of recording time. In either case, short recording limits can frustrate callers. For individual messages, look for an answering machine that allows at least one minute per call. Even better are answering machines that offer 2.5 minutes per message, since this is enough for even the most detailed request. Total recording time tends to be a bigger issue for digital answering machines than cassette recorders. Many digital answering machines can only hold 10 minutes of messages, which may translate to 20 or 30 messages. If you suspect that this is not enough, look for an answering machine that offers 15 to 30 minutes of recording time. Some now come with 60 minute recording time. If you are frequently away from your office, you will want to purchase an answering machine with remote access features. The most basic answering machine remote access feature is message retrieval. Users can pick up messages on the road by entering a touch-tone password after calling. In most cases, other touch-tone buttons allow you to skip, rewind, or delete messages. Another useful feature is remote activation. This allows you to turn on the answering machine via telephone in case someone in your office forgets to activate it. One money-saving feature is toll saver, which modifies the number of times the phone will ring before the answering machine picks up. Typically, the answering machine will answer a call immediately when there are new messages. If no new messages have been recorded, the user can hang up before the answering machine picks up the line. Like computers, digital answering machines are increasing in memory as prices continue to fall. Some answering machine manufacturers are suggesting that by the end of the year, low-end digital answering machines will go for under $30. From high end answering machines that go for about $200, expect nothing less than features like incoming data line recognition, remote access and two-line capability, multiple mailboxes, pager notification, and more. If you often find yourself trying to decipher incoming messages, purchase an answering machine with variable speed playback. This can reduce the bother of listening to long-winded callers and aid in deciphering messages from fast-talkers. High-end digital answering machine systems offer voice mailboxes and other simple voice mail features at a fraction of the cost of voice mail service bureaus or low-end voice mail systems. These days, the question isn't so much which phone answering device (TAD) to buy, but whether to go with your own hardware or a commercial voicemail service. There are many advantages to the latter, but for personal or home-office use, a dedicated answering machine is still the most economical and convenient choice. Answering machines that use full-size cassettes are virtually impossible to find, having been replaced by answering machine models featuring the smaller micro cassettes and digital recording. Too bad -- in spite of their often clunky operation, full-sized cassette answering machines offer superior sound quality compared to either of their successors. Micro cassette-based answering machines take up little space, which is an advantage. But micro cassettes are somewhat unreliable and are slightly harder to find than standard audio cassettes. Also, their narrow tape width means limited sound quality -- including tape dropouts, which can obscure one digit in a caller's phone number -- though most people don't seem to mind. Digital answering machines fall into several categories. Some are digital only in features, such as time stamp, and still record outgoing and incoming messages on analog tape. Others may recite the outgoing message from a memory chip, while recording incoming messages on analog tape for maximum sound quality and capacity -- a nice compromise. Others are purely digital, recording all messages digitally, using chips. The advantages of eliminating moving parts are obvious, but there are substantial variations in total recording time and sound quality between answering machine makes and models. Make sure you check the total recording time and get the most for your answering machine needs. A range of 14 to 20 minutes is common but 60-minute answering machines are also available. The newest TAD answering machines offer multiple voicemail boxes, usually at least four, which can be operated with independent passwords. This can be a boon to the small office/home office (SOHO) or even a busy family, and begins to approach the flexibility of a commercial voicemail system. Other nice digital answering machine features include random message playback and quick deletes. TAD answering machines are now a commodity, and you can pick up a functional tape-based unit for as little as $30. Between $50-75 expect micro cassette-based operation and some features that were esoteric only a few years ago, like touchtone remote message retrieval and message time stamp. Most TAD answering machines fall into the midline category. Expect niceties such as an integrated phone, the ability to record conversations, tape less operation, and occasionally the ability to assign more than one outgoing message. Features, not construction, account for price differences , so you can save some money if you don't need all the bells and whistles. You should be able to buy a capable full-featured answering machine for less than $100. Fancy answering machines with built-in speakerphones and extra memory and other features might run as high as $200. At around $200, mere answering machines give way to sophisticated digital voicemail systems, which pack the power of several answering machines built into a single box. If you need this kind of capability for more than a handful of people, consider whether a commercial voicemail system wouldn't be a more economical choice in the long run.
