DVD RAM Storage Media for Voice Recording

Archiving to ‘optical disks’ (e.g. CD, DVD) is becoming obsolete.

Historically, optical disks had a place at the data storage table because it was the format that met the regulatory requirements of immutability and longevity. Certain calls needed to be stored in WORM (Write Once Read Many) data formats and be viable for decades. Optical has provided this calls archive capability for years and its cartridge form-factor enabled it to be carried off-site easily, providing a solution for DR (Disaster Recovery) as well. But things have changed.


Optical has never enjoyed the data density that magnetic storage does, so in order to keep increasing media capacity, new formats were continually developed. This required a migration of data from the old to the new format, or keeping the old technology drives to play legacy media. But migration was expensive, both in upfront costs and disruption and keeping old hardware around was also problematic, especially when it wasn’t being manufactured anymore.

Also, specifically for DVD-RAM storage, the old 2x speed DVD-RAM media cannot be used on the current 5x speed DVD-RAM drives. DVD-RAM 2x speed media is becoming difficult to get.

Some components are relevant to high level business managers who want a quick glance at the overall level of performance in the site. Other components are relevant to supervisors who want to see how well the agents that they supervise are performing. Further, there are components that are relevant to agents who can see how well they are performing compared to their colleagues over a period of time.

Voice Recorder Storage Center Capacity & Network Bandwidth Calculation

Storage Capacity

Calculating the required net storage capacity can be done using the following formula:

Daily storage capacity = (“Average number of calls per day”) ´ (“Average call audio size”)

The average call audio size can be calculated using the following formula:

Average call audio size = (The audio compression in Kbytes/sec) ´ (Average call length in Seconds)


For Example, in a site using ACA 5.6 Kbit/sec compression for recording by, having an average call length of 3 minutes, the average call audio size will be 3´60 (seconds) ´ 5.6 Kbit/sec = 1008 Kbits = 126 Kbytes

(8 bits = 1 bytes)

Referring to the storage capacity per day, if this site has 20,000 calls per day and is required to store them all, then the average daily net storage capacity required will be 20,000 calls 126 Kbytes (based on ACA 5.6 Kbit/s compression) = 2.4 GB.


Note: the figures above refer to storing the audio in a proprierty format. Saving the audio as PCM WAV files multiplies the net storage required by 4 compared to ADPCM 16 compression and by more than 11 compared to ACA 5.6 Kb/sec (as the audio compression used when storing in WAV format is 64 Kbit/sec).

Required Network Bandwidth

Calculating the required average network bandwidth can be done using the following formula:

Required network bandwidth = amount of data to be archived / the time used for archiving.

For example, if the data to be archived is 20GB in size and it should take 24 hours to complete the archiving procedure then the required average network bandwidth is 20GB/24hour = 0.83 GB/hour = 242.4 Kbytes/sec.

How to choose a voice recorder

It may not be easy for those who are tasked to choose a voice recorder for the first time.

First you need to identify those phones that need recording, the quantity and the phone model. This is important because for extension side recording, the price will vary with the number of recorded phones. The voice recorder selected must be able to record the digital or VoIP phone in the same box.

The recordings will first be in the hard disk, which typically 1TB in today’s standard, either Raid-1 or Raid-5.

 Recorded calls can be archived into Removable Disk Cartridge or Network Archived Storage depending on the company’s call retention policy.

Ease of Call search is of primary importance in choosing a voice recorder. Typical search criteria are caller’s number, dialled digits, duration, date and time.

For Call Centre and Trading environment, one can opt for CTI integration for call retrieval via agent ID or trader’s ID.

With API integration, calls can also be retrieved by reference number and so on.

Today’s technology also allow call search by word spotting and emotion.

Please do not hesitate to contact us for more information.
