SunRocket launched a low-cost VoIP plan around $10/month with 200 outbound minutes and unlimited incoming calls. The company folded in 2007. Today VoIP is mainstream, with better codecs, standards, and business-grade options; pick providers based on reliability, E911 support, and number portability.
VoIP (Voice over Internet Protocol) sends phone calls over the internet instead of copper lines. Modern VoIP offers cost savings for long-distance calls, feature-rich plans, and multi-device support, but depends on broadband and may have emergency-call and power limitations.
Modern telephone intercoms use IP, VoIP and video to connect rooms, control doors and integrate with phones and mobile apps. They offer zoned paging, scalable installations and remote access, but require attention to network security and local privacy rules.
Upgrade legacy analog lines to Cisco IP phones and cloud calling to gain clearer audio, centralized management, modern security, and integrations that boost productivity.
Overview of modern paging: intercom/overhead audio for noisy public areas, phone-network paging for office environments, and IP/VoIP or cloud paging for multi-site, managed deployments.
A caller ID box decodes short data sent between rings to display the incoming number and sometimes a name. Modern networks and apps now supplement or replace this with database lookups, VoIP signaling, and anti-spoofing measures.
Two-line cordless phones remain useful for households that need separate lines, reliable in-home coverage, or VoIP bridging. Modern DECT systems (1.9 GHz) provide clearer audio and encryption; choose DECT and VoIP-compatible bases for best results.
Intercom systems evolved from audio-only units to IP-connected, video-capable devices that improve security and convenience in hospitals, airports and multifamily housing. Modern features include mobile apps, PoE installation, encrypted communications and integrations with access control.
VoIP transmits voice and video over the internet, offering cheaper international and business calling. Learn what you need, how free and paid options differ, and practical limits like emergency calling and call quality.
Long-range cordless phones extend traditional base-and-handset systems using DECT, external antennas, repeaters, or VoIP links. They work well on farms, campuses, and inside facilities where you want local mobility without monthly cellular fees, but true long-distance operation requires additional infrastructure or network links.
