For a variety of reasons, many industries use voice loggers to record all incoming and outgoing telephone conversations. Typical examples include corporate call centers (we've all been told that our "call may be recorded for quality purposes"), 911 emergency systems, and telephone-executed stock trades (the beep on the line indicates that you are being recorded). In addition, most companies these days have a voicemail system.
Traditionally, voice loggers have been separate PBX-attached units which record all telephone conversations onto a computer tape or disk, typically a 4mm (DDS) tape, AIT tape, or DVD-RAM. These media are usually recorded in a manufacturer-specific format and can use a variety of different audio encoding methods. They usually can only be played back on the original equipment, sometimes only one call at a time. A voice logger tape can contain 10000+ conversations per tape (100+ hours), and some models can contain ten times that. Manufacturers of voice loggers include NICE (NiceLog & NiceCall), Dictaphone (Guardian & ProLog), Racal (Wordnet & Mirra), Thales (Wordnet), ASC (Marathon), Comverse, Tantacomm, Eyretel, Lanier, and Mercom.
Voicemail systems are frequently based on proprietary hardware, particularly the older ones. These systems back themselves up onto tape or disk, typically a quarter-inch cartridge (QIC) tape, magneto-optical (MO) disk, or CD-RW. Examples include Audix (manufactured over the years by AT&T, Lucent, and Avaya), and Meridian Mail (aka CallPilot) by Northern Telecom (aka Nortel).
For various reasons, you might want to retrieve the audio from your voice logger or voicemail tapes and disks. You might be migrating to a newer system and want to store the legacy audio in your archive. Or you might be involved in a lawsuit and need to turn over the recordings to opposing counsel, but yet you might not even have that old logger around anymore. Either way, Electrical Science can help.
Electrical Science can extract the call catalog and audio from your voice logger and voicemail tapes. The call catalog will typically contain the start time, duration, and extension for each call. Depending on the logger model, the catalog might also include caller ID, dialed number, and additional metadata. We can do a wholesale recovery of the entire tape, or we can just extract the catalog or audio for a given channel or date range. We can deliver audio as WAV files or in your preferred format. (Note that MP3 is not a good format for delivering voice-quality audio, and we'd be happy to tell you why.) We can also perform data recovery on damaged or partially-recorded (improperly ejected) media.
