Analog telephone sets are still relevant for specific business applications in 2026, primarily due to their extreme reliability during power outages and their suitability for specialized, low-tech functions. While many businesses have transitioned to Voice over Internet Protocol (VoIP) for advanced features and cost savings, analog, or Plain Old Telephone Service (POTS), remains crucial in sectors requiring high security or in locations with poor internet connectivity.

Guestroom phones are still needed in hotels for safety, ease of use (especially for older guests/emergencies), and reliable service requests (room service, wake-up calls), though their form is evolving into more integrated, IP-based, or smart devices to complement mobile tech, meeting needs for guests who prefer simple, direct communication or lack mobile service.
