VoIP MOS test results are at least as good as PSTN – it’s official

The official ITSPA Awards test results make for very interesting reading. All entrants for the Best ITSP, consumer and SMB categories had their services independently tested by Epitiro.

There were 16 entrants for these two categories. On average Epitiro made 400 calls per company and then took over 50,000 technical measurements. Calls were all made over the same broadband connection.

All bar one company tested reached the ITU-T P.862 PESQ MOS Quality rating in excess of 4.0 thus meeting the ITU-T P.800 subjective rating of ‘Excellent’. The one that didn’t met the subjective rating of “Good”.

Consumer VoIP MOS downstream average = 4.3
Consumer VoIP MOS upstream average = 4.25

Business ITSP (SMEs) MOS downstream average = 4.25
Business ITSP (SMEs) MOS upstream average = 4.25

There is no real reason why there should be a difference between consumer and business downstream MOS.

Packet Loss was very minimal. Only three companies experienced any packet loss (minimal – 1.3% was the highest loss)

Call set up times were in general on a par to the PSTN standard of 2.5 seconds and better than mobiles.. The customer would experience no difference.

These are great results and are a serious independent endorsement of VoIP as a mainstream communications technology that can replace traditional PSTN services.

PS MOS = Mean Opinion Score and represents perceived quality of a telephone call.

2009 ITSPA Awards – get yer entries in

The first Annual ITSPA Awards bash last year was a huge success, not least because Timico won the Best Unified Communications provider award!  The event was held in the House of Lords Members Dining Room and had a fantastic turnout. We ended up in a few bars around Westminster and succeeded in not losing the trophy.

This year we are doing the same again and hopefully will have another great turnout.  If you are reading this and are in the VoIP business you should think about entering. There are categories for both Service Providers and equipment/solution vendors, details of which can be found here. This year’s entrants are also going to be subject to expert testing by Epitiro.

The winners will be announced in the House of Commons Strangers Dining Room where the ITSPA Awards will take place on 10th December 2009. I look forward to seeing you there. Come and tap me on the shoulder to say hello.
