there is two-way audio, but the call drops after 20 or 30 seconds

i have an issue with inbound calls the contact header IP contains my Private IP Address, As the provider is required to send the ACK back to the IP Address in the Contact header, the ACK is being sent out to that Private IP Address
I modified the IP through the option available in the trunk and set the public IP, but it still uses the private IP.
Error
Event ID : 50029

Hi, is this a dedicated machine? If you are using twillio just make sure to use the default template and set the voip provider as mentioned in this document.

Running a dedicated machine make sure to run the firewall checker and pass it with success.
