I am not calling with a vapi number I bought a voip service from Türkiye I sent your IP information and received the necessary permissions. I was able to make calls until yesterday but today no calls are accepted. Unfortunately I don't have detailed SIP log so I can't understand the problem. I was using Sip Trunk and there was no problem until now. It started today. The sip addresses I added before are not making any calls as of today. Previously it was giving this error "An error occurred in this call: call.in-progress.error-sip-telephony-provider-failed-to-connect-call". Now only Customer is busy. Unfortunately there is no sip connection log.

Since the error changed from "provider-failed-to-connect" to "customer-busy", this suggests your telephony provider is now receiving the calls but reporting the destination as busy. Contact your VOIP provider in Türkiye to: 1. Verify your account status is active 2. Check if there are any restrictions on your service 3. Request SIP logs from their end to identify why calls are being marked as "busy" This is likely an issue on the provider side rather than with your Vapi configuration.
