Why Businesses Upgrade from Legacy Phone Systems?
Businesses replace legacy phone systems to eliminate high costs, outdated infrastructure and communication inefficiencies that reduce productivity.
PSTN Technology Limitations
PSTN uses 1960s-era circuit-switched technology dedicating entire channels to single calls. It supports voice-only communication, lacks software integration and wastes bandwidth during silence. Copper wiring degrades over distance weather and time causing call-quality issues beyond 3 miles from switching stations. Hardware maintenance averages $50–150 per line annually with no CRM analytics or mobile support.
Rising Maintenance Costs
PBX systems require specialized technicians with service visits costing $200–500 per incident. Annual maintenance equals 20–30% of initial investment. Hardware replacements every 5–7 years cost $5000–15000 for 25 users. Emergency repairs cost 50–80% more and proprietary parts are often overpriced and scarce.
Missing Modern Features
Legacy systems lack CRM integration call analytics mobile access voicemail-to-email video conferencing team messaging and automated attendants. Remote work is either impossible or expensive. Call recording requires separate equipment.
What Are VoIP Services for Businesses?
VoIP services are cloud-based communication platforms that transmit voice as digital data over internet connections. Using packet-switching instead of circuit-switching VoIP allows multiple calls over shared bandwidth using existing broadband infrastructure.
How VoIP Works?
Voice signals are compressed into digital packets routed via IP networks and reassembled at the destination within 20–150 milliseconds. Unlike PSTN VoIP uses bandwidth only when voice data is transmitted improving efficiency and scalability.
