Hi Ayush,
I can help with this. The issue is clear from your logs: your LLM provider is timing out (taking 10+ seconds) when generating the opening message, which causes the silence and dropped calls.
The dynamic opening message requires an LLM call before the agent can speak, and if that call times out, you get dead air.
Quick question: What LLM provider and model are you using for this agent? Also, is the dynamic opening message pulling data from an external API or database that might be adding latency?
