AI Tools Fail to Address Call Drop Issue | Frustration Grows Among Users

A rising concern among developers is the high call drop rate in voice AI systems. Recent findings reveal that despite claims of 99.9% accuracy, 15% of calls are lost or derailed, leaving many baffled.
The Crux of the Problem
Developers and engineers are questioning the reliability of voice AI tools. As these tools become increasingly relied upon, issues like dropped calls and miscommunication leave users frustrated.
"I’ve watched too many calls derailed and not known why," said an industry engineer.
Surprisingly, the real issue isn’t with the voice agents' better models for language processing (LLMs) or speech recognition (STT), but a lack of actual observability. Many systems suffer from blind spots, leading to these confusing call failures.
Hidden Failures in Voice AI
The absence of transparent metrics leaves many without the ability to diagnose problems effectively. Current systems lack crucial insights, including:
Guardrail activation tracing that fails to inform users why certain errors were flagged.
Timing metrics that obscure where delays may be occurring in the overall process.
Breakdowns between components like audio, LLM, and telephony which are vital to understand.
This lack of insight creates challenges in identifying the cause of broken call flows. As one user pointed out, "Debugging feels like trying to find a needle in a haystack. No logs show the true extent of what happened."
The Need for Change
The current iteration of voice AI tools feels outdated. It mirrors backend engineering practices from before modern observability tools like Datadog were introduced. The problems range from:
Silent call failures where calls freeze or time out without warnings.
Hallucinated safety messages that disrupt communication without cause.
Interestingly, as issues continue to mount, the newly emerged platform Rapida promises a solution by integrating full per-call observability, which includes logs for safety refusals and timing breakdowns. This would help developers understand their systems beyond just surface-level metrics.
Key Insights
△ 15% of calls drop or derail despite claims of 99.9% accuracy.
▼ Lack of observability hinders debugging efforts.
※ "Guardrails should help you, not hide the truth from you.”
As developers gather more information, one thing is clear: voice AI technology needs a serious overhaul to bring the complete transparency currently lacking in the field.
The call for engineers and PMs to contribute to solutions at Rapida is echoed across industry user boards, as many seek to diagnose and solve these persistent issues.
A Glimpse Into The Future of Voice AI
There’s a strong chance that the call drop issue will drive significant upgrades in voice AI tools within the next year. As user frustrations rise, developers may prioritize transparency and observability, leading to the implementation of new metrics and diagnostics. Experts estimate around 70% of industry players will adopt comprehensive logging features to ensure smoother call experiences. The push for a standardized observability structure could pave the way for a new generation of voice AI that prioritizes accuracy and user satisfaction, promising to reduce the current 15% call failure rate significantly.
The Unseen Echoes of History
This situation finds an unexpected echo in the evolution of early smartphone technology. Much like the early days when dropped calls plagued connections, creating widespread discontent, voice AI faces similar hurdles today. Just as those phone manufacturers were compelled to innovate and improve their services to meet consumer demands, so too must this sector adapt to overcome its own barriers. The drive for reliability in communication has fueled advancements in technology, suggesting that the current challenges within voice AI could lead to innovations that redefine how we engage with automated systems.
