I just get the Options on my Firewall but Not the invite to establish the call. Is Theresa y posibilit ir you can confirm from which Ports valí si sending the call. I have These: 44.229.228.186 and 44.238.177.138 Can you confirm if there are any other IP Here is my latest call ID 09d0862c-c6f3-4972-b865-4e7ad78751c0

Thanks for sharing the details and your call ID. Based on the information available, I don't have details about the specific ports or any additional IP addresses used for SIP signaling or call establishment beyond the ones you've listed. If you have any other questions or need further clarification, feel free to ask!

To help track down this issue, could you share one or two: - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help us figure out what went wrong!

Heppened today at 00:30 am and we expected the call to connect to the customer and the error was found on the call log status

Looking into it

Ok thanks

No news yet it was weekend

@paolobertini Let me know how did you solve the problem and how SIP trunking is costing you per minute?
