AI-Ready Voice Infrastructure: Is your carrier at fault | Bandwidth
Blog post from Bandwidth
Voice AI performance depends not only on speech-to-text, language-model, and text-to-speech components but also on the underlying telephony network, which handles PSTN connectivity, SIP signaling, routing, number provisioning, and compliance. Citing Hamming AI analyses, the piece states that production voice agents commonly have 1.4–1.7 seconds of response latency, while natural conversation generally requires 200–400 milliseconds; it associates latency above 800 milliseconds with lower task completion and notes that many call abandonments occur at 1,200 milliseconds or more. It argues that reseller-based carrier services can introduce opaque intermediary hops, geographic inconsistency, and congestion, whereas direct carrier ownership or national-operator status may provide greater control, visibility, and routing performance. The text outlines maturity tiers for voice infrastructure, ranging from manual routing and limited observability to programmable call control, real-time SIP monitoring, portability, and layer-specific failure attribution. It identifies geography-dependent latency, volume-related abandonment, unchanged latency after model optimization, high overall response times, and SIP failures as signs that network infrastructure rather than the AI model may be the bottleneck, and advises organizations to evaluate carrier capabilities before scaling voice AI deployments.
