Curse of the TDM die-hards

Many companies have taken a long wait-and-see attitude towards IP telephony, but market forces and changing technology may force them to reconsider. Fourth in a series


This is the fourth post in a series that explores five reasons to revisit the business case for deploying IP telephony and VoIP in your organization. Read part one: 2 ways to dramatically lower VOIP TCO, part two: Keep talking — no matter how bad things get and part three: How IP Telephony Can Lift You To the Cloud

“Why should I change what is not broke?”

This simple question, deeply rooted in popular wisdom, has bedeviled IP telephony vendors and evangelists for more than a decade now. No matter how skillfully they were able to paint rosy pictures of efficient VoIP connectivity or blissful unified communications environments, no matter how shiny the buttons  or how slick the displays of the new phones they were able to wave in front of prospects, many of their pitches would still fizzle after that little innocuous question was asked.

Nobody had an easy answer. After all, the long established digital TDM systems kept working and serving flawlessly a multitude of businesses of all sizes. The old equipment was well designed, feature rich, reliable and well understood in terms of installation and maintenance requirements. The original cost had been amortized long ago and organizations were essentially enjoying cost free performance.  Making the case for new investments in a replacement IP telephony system was no doubt a difficult sell.

Things are changing, however. Communication systems vendors trying to ride the wave of new technologies and applications are finding it hard to devote the same attention and level of support to the traditional TDM product lines. Under the strain of competitive pressures and budgetary constraints, popular products are discontinued or merged into different lines. On an even more fundamental level, the same dynamics causes vendor companies to disappear altogether or be swallowed by competitors. Business organizations that have clung for too long on their old communication systems are starting to have difficulties obtaining support or upgrades from the vendors.  The more they postpone the decision to make the transition to modern IP telephony-based systems, the more risk of disruption they incur and the more they are going to have to pay when they eventually make the decision to move.  Wait and see policies that used to be smart are becoming shortsighted and expensive.

In the meantime the new technology has matured and proven its worth. VoIP, unified communication, SIP trunking have all reached new levels of performance, resilience and ability to deliver a solid ROI.  Clearly, the time has come to leave the past behind and join the move to the future. That‘s another good reason to have a new look at IP telephony and embrace all the positive changes it represents.

    Excellent observations. There are many IT/Telecom Managers running their business on TDM technology systems that are10-15 years old. Their support has been manufacturer discontinued, parst are at times impossible to find and don’t offer any Unified Communication benefits. These Managers are putting their business at risk. Now is the time for them to replace this aging infrastructure with purpose built IP appliances that offer N+1 redundancy or Mobility Routers to support smartphones.
