Multi-Tenant VoIP at Scale: Breaking the Shared Infrastructure Barrier

Multi-tenant VoIP platforms hit critical scalability walls when shared infrastructure saturates, causing cascading failures that impact all tenants regardless of their usage. The article exposes three specific failure modes—RTP jitter from context switching, SBC routing saturation, and database lock contention—that disable entire networks. Decoupling signaling, media processing, and analytics across isolated infrastructure tiers emerges as the only viable path to scaling beyond these fundamental system bottlenecks.
