An error occurred in this call: call.in-progress.error-sip-telephony-provider-failed-to-connect-call

I am trying to make a call from vapi using the Nvoip sip connection.
I created the connection with the information in the image 1 (vapi1).
I already tested this SIP Configuration Values using MicroSip and It worked, I was able to make a call using the Nvoip number +551147099419.
The Configuration is in the image 2 (vapi2)
I created the phone number in Vapi and clicked "Make a Call", image 3 (vapi3)
The call log is in the image 4 (vapi4)
The call log details with the error is in the image 5 (vapi5)
