Typical customers range from small and midsize businesses to large enterprises, healthcare providers, financial institutions, and government agencies that require secure, reliable voice and data connectivity across multiple locations and remote workforces. Key risks include rapid technology obsolescence, dependence on carrier networks, cyber threats to voice and collaboration platforms, and compliance with FCC rules, privacy laws, 911 and emergency-calling regulations, and sector-specific standards. In 2024–2025, the industry is being reshaped by cloud-based UCaaS, AI-powered contact centers, tighter integration with CRM and collaboration tools, and 5G-enabled, mobile-first architectures.
