The 2025 PSTN switch off is having a huge impact on the elevator industry. Most lifts utilise PSTN lines for their emergency phone lines, and although some businesses have already invested in ISDN as a replacement, they will need to re-evaluate their services as their existing safety solutions will soon become redundant.
Unfortunately, this means that a different solution will be required to deliver emergency communication in lifts moving forward. The all IP-network is promoting data-only connections such as leased lines, FTTP and SOGEA, but all of these solutions require voice to be delivered over the internet. This often comes at an additional cost for hosted telephony.
So what are your alternatives?
