This is the last report from Enterprise Connect 2015 in Orlando and it feels natural to keep it around a theme of wireless and IP.

If we start with the impressions from customer meetings in the Konftel booth, clearly the SIP solutions for 300Wx scored high. The concept of using stable and secure HD wireless through DECT with IP connected base stations is strong. We previewed a coming Konftel IP DECT base and a couple of third party products suitable for the US market.

Jim Gat and Jeff Newsom from the Detroit based VAR Business Communication Systems were among many to show interest in that:

“We are looking for a better wireless offering than we have today. The long battery time in 300Wx is really appealing together with the ability to connect to IP”, says Jeff.

Towards a meltdown?

But IP also raises challenges that needs to be adressed. One of the last EC 2015 conference sessions had a dramatic touch to it: “VoIPmageddon – Are We Headed for a Telephony Meltdown?” It was presented by Phil Edholm, consultant and a strong influencer in the enterprise communications industry that has held leading positions at Nortel and Avaya.

Phil Edholm hits the alarm button, stating that VoIP quality is degrading and will get worse in the coming years if the enterprise customers, service providers and industry as a whole doesn´t answer to the challenges. I won’t go into detail about all the causes to this problem, but these are the most important:

  1. A strong growth in VoIP traffic and number VoIP endpoints, with mobile IP calls (VoLTE) close to massive rollout.
  2. Many VoIP calls still involve traditional telephony (TDM) with transcoding and complex routing scenarios.
  3. Managing latency in an IP call might be complex.

Phil Edholms postulate is that at least 5 – 10 percent of VoIP to VoIP calls that are not peer to peer suffer from percieved quality issues today. That will increase significantly in the coming five years. The impact is strongest on conferencing calls, where bad endpoints and connections ruin the overall experience of quality.

“We might face a situation where 100 percent of conference calls suffer from poor quality within three or four years”, states Phil Edholm.

Action items

But there are ways to avoid the threat of a “VoIPmageddon”. Phil Edholm calls for action and provides a list of items to adress. Here are a few of them:

  • Eliminate TDM trunks.
  • Pick SIP trunking providers based on peering and traffic paths, not only price.
  • Minimize transcoding.
  • The industry should agree on not more than two VoIP codecs.
  • Move to peer to peer implementations and open federation at the IP media level, among all vendors.
  • Demand echo cancellation in all VoIP endpoints.

“You should go and ask your conference phone vendors about the echo cancellation and latency specifications in the products. And that goes for all IP endpoints”, says Phil Edholm.

Yes, we at Konftel are more than happy to discuss these issues with you and we are confident that our OmniSound technology helps in keeping the voice quality good also in IP solutions.
