@Shubham Bajaj Till yesterday our vapi calls were going perfectly but for some reason, they started failing today even though we did not make any changes. The call scenarios which were handled perfectly, they started failing all of a sudden. Below are some calls. Can you tell me what might be the reason? e85a9fab-8399-4b38-ad7f-dc65b03be471 : Multiple voicemails left ea0f6190-c96c-4830-b478-c40f6bed58b3 : Multiple voicemails left 0bebeec0-54f4-4579-bfbf-3954506ba5ec : Customer could not hear our agent 50a46f05-935f-40a2-a71e-e3fa753ee663 : Not answering appropriately
