PSTN Switch Off: What It Means for Business Phone Systems
Traditional copper telephone networks are being retired worldwide. Carriers are moving customers from PSTN and ISDN services to IP-based alternatives. For businesses, this means evaluating existing phone systems and planning migration before lines stop working.
Why Networks Are Retiring
Maintaining separate copper infrastructure is expensive compared to delivering voice over broadband and fiber networks. Regulators and carriers across regions have announced shutdown timelines stretching into the late 2020s and 2030s.
Business Impact
Organizations using analog lines for phones, fax, alarms, elevators, and POS terminals must transition these services. Legacy PBX systems connected to ISDN trunks will need replacement or gateway connection to SIP services.
Migration Path
Redstone REX IP-PBX systems replace legacy PBX cores, while RGW gateways preserve analog devices and connect to SIP trunks. EGW50 4G LTE gateways provide backup paths where wired redundancy is unavailable.
Planning Timeline
Start by auditing current lines, devices, and contracts. Identify critical services that must not be interrupted, and plan migration in phases aligned with carrier deadlines.
