Yes, different responses between Twilio phone calls and web interactions is a known issue! 😔 I've found several potential causes in our documentation:
Network and Configuration Differences
Variations in network latency and configurations between web-based interactions and phone calls can lead to differences in performance and response accuracy. Twilio's handling of calls differs from direct web interactions due to telephony-specific constraints.
Common Technical Issues
1.
Connectivity Problems - Timeout errors and connection failures between Twilio and VAPI servers can cause inconsistent responses
2.
Audio Routing Issues - Differences in how calls and audio are routed can lead to varying audio quality and recording issues, especially with international numbers
3.
AI Loop and Voice Recording Problems - Some users experience the AI getting stuck in loops or voice not being recorded properly
Voicemail Detection Challenges
Twilio's Answering Machine Detection occasionally fails or triggers too early, affecting the system's accuracy and user experience.
These issues can definitely be frustrating! For more consistent responses, you might want to check your configuration settings for both Twilio and VAPI, particularly focusing on correct URLs and parameters.
Is there a specific type of difference you're noticing between the phone and web responses?
