A user logged in from Shanghai and we got this from the Vapi logs: "An error occurred in this call: call.in-progress.error-assistant-did-not-receive-customer-audio" We are troubleshooting and wondering first if Vapi is available in China Call Id: 724aad45-fa74-433c-b788-596b16c3aa1c

Hi there! 👋 Based on the error you're seeing, there might be some network-related issues affecting your Vapi call in China. The error "call.in-progress.error-assistant-did-not-receive-customer-audio" suggests that the assistant couldn't hear the customer's audio, which is sometimes referred to as a ["deafness bug"](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1340235729204285510). To help troubleshoot this issue better, could you please provide some additional information: 1. What transcription service are you using? (Some users have reported that Deepgram might block certain IP addresses, which could be relevant in China) 2. Have you checked if there are any firewall configurations that might be blocking SIP traffic in your user's network? 3. Are you experiencing high latency or packet loss when connecting to Vapi servers from China? 4. Have you tried any other configuration changes to address this issue, such as modifying the

start_speaking_plan

or

transcriber

settings? This information would help us determine if the issue is related to China's network restrictions or if it's a different configuration problem.
