Evaluating VoIP Business Phone Services – Top Ten Reviews


A business phone is a company’s lifeline.  For most companies, significant marketing efforts are made using the business phone number, which is why many business owners prefer to obtain business VOIP phone services through cloud-based providers due to their configuration flexibility and cost-effectiveness.

Quality Standards for Business Phone Services

There is no point in saving money on business phone services if the call quality is horrible. The good news is that the quality standards for VoIP and voip mobile phone services improved significantly over the past decade.

The industry standard for measuring the call quality of VoIP services is the Mean Opinion Score (MOS). The MOS evaluation focuses on listening quality, conversational quality, and transmission quality.

The MOS includes an evaluation and ranking of the calls on VoIP services for the following:

  • Bandwidth: The throughput capacity of download and upload speeds.
  • Latency: The speed of the link to another party.
  • Jitter: The timing gaps between the data packets.
  • Packet Loss: The pieces of data that are missing.
  • Compression: VoIP compression ranges from lossless 1:1 to low quality 12:1.
  • Codec: The coder/decoder used to convert the analog sound to digital transmission.

Phone call quality is higher with more bandwidth, less latency, lower amounts of jitter, less packet loss, lossless compression (1:1), and when using an efficient codec. Network administrators periodically test a VoIP system for quality. A minimum MOS of 4.3 out of 5.0 is the preference for quality business calls.
