Rightful so, the last week has been a heavy saturation of the the Avaya Flare™ experience and Avaya Desktop Video Device on this blog and many other media outlets. This was a massive and successful product launch from our company.
But, this doesn't mean that our other work went by the wayside, and in fact I am pleased to highlight another welcome development. Just before last week's launch, Avaya received some very positive, and green news. Tolly, a global provider of hands-on IT research, published an energy consumption evaluation, commissioned by Avaya, Avaya 9600 Series Voice over IP Phones: Energy Consumption Evaluation versus Cisco Unified IP Phone 7900 Series.
"This is yet another gratifying proof point of Avaya's commitment to sustainability. Energy efficiency is a key aspect of our products sustainable operations and the results from the third party verified Tolly report are another proof point." said Geoffery Baird, Avaya's Sustainability Officer.
Four VoIP phones from each vendor were tested in various states of activity in order to provide more granular data points for energy consumption modeling.
The Bottom Line: here are the take away results from the report. You should also check out the chart that is included in this post. The chart pretty clearly demonstrates the tested results, and the energy savings that Avaya can deliver with our 9600 series phones.
- In every scenario tested by Tolly, the Avaya 9600 phones consumed 40% to 60% less energy than the comparable Cisco offering
- Over 80% of the overall energy consumption of VoIP systems can be attributed to the VoIP phones (this means that power savings on the phone front can really add up. Because they are discrete end points in a solution, the power draw of the many phones in a solution can get missed)
- Avaya VoIP solutions (gateways, servers, IP Phones) were validated by Tolly to use 45% less energy, produce 45% less CO2 and lower electrical expense by 45% versus Cisco.
Other folks in the industry see the value of efficiency at the phone level in a solution as well. For instance, Gary Audin, from Delphi authored a piece for No Jitter that looked at the math behind the power draw from IP phones, using this report as a starting point, The IP Phone Power Bill Can Be High.
The TCO for VoIP should include the electrical power bill. The cost to power the IP phones can be much higher when comparing one vendor's power consumption vs. another vendor. This becomes apparent in the Tolly Enterprise's report Avaya 9600 Series Voice over IP Phones: Energy Consumption Evaluation versus Cisco Unified IP Phone 7900 Series.
What was the methodology of the testing?
Each VoIP solution was paired with a LAN switch from the same company, to incorporate the base power management systems in place at the solution level. Then, for each test, the phones were connect to a LAN switch and then measured in each of the five modeled use states, Minimum: lowest display setting, Normal Off Hook: phone in use, Normal On Hook: phone not in use, Energy Saver: testing with the specific energy-focused power management system enabled and Maximum: in use with speakerphone.
Nice review. Voip phone sets are useful for those users who prefer a look and feel of ordinary phone. However, as we all know that voip service can be used via soft phone also.
