Mobility frequently gets top billing on the list of strategic priorities for many organizations today and the focus is well deserved. Mobile devices and applications expand communications potential and redefine the way in which employees are enabled to communicate. While mobile enablement is important, it may not be the most critical telecom priority of the decade.
PSTN transitioning is happening now and the TDM network is being replaced with VoIP. This network change has been underway for several years as carriers replaced and upgraded the core of the network with IP switching and transport facilities. In many cases, subscribers only became aware of the changes as they upgraded connections to the network with VoIP and SIP services. The upgrades and changes were perceived as positive by all parties. Today, the transition to VoIP is expanding beyond the core, past the edge and to all end subscribers; the last mile technology is being transitioned from TDM to VoIP. This change will be seen by many as a positive evolution in the technology of the network, yet some will be left scrambling in the final hour to invest in new hardware and carrier services when the last TDM circuit is sunset.
Carriers are rapidly decommissioning TDM services and are pacing towards transition by the end of the decade. This means that commercial (and residential) customers must have a technology strategy in place compatible with the post-transition VoIP network. CAPEX investments may be significant for some and all will see changes to OPEX associated with carrier services. Formulating and executing on PSTN transitioning strategy may not have the same allure and excitement as mobility enablement, but the voice network as we know it will forever be changed in the near term and everyone must be prepared.
The time is now. Solidify your PSTN transition strategy and execute quickly before TDM becomes a relic of the past.
