SIP Trunk disconnections

[apitsos]

Hi there!

I am having a new problem. We are facing some issues with SIP trunk disconnections. A colleague told me that he couldn't place a call and I connected to the 3CX dashboard to see what is wrong. The moment I connected he told me that his call could go through and he did it. I did nothing. But I noticed at the dashboard the events logs you can see on the below screenshot.



I am not really sure what is happening here and why our SIP Trunk is getting disconnected. I am also not sure about the reason provided here (Block WAN requests is ON).

I would really appreciate any input.

Thanks a lot in advance for your help!

Hi,

These are two separate messages.

- The first one is your provider rejecting your registrations or calls with a 403 (contact them for details)

- The 2nd one is some random hacker port scanning you (don't worry this is a regular occurrence)

Hi @JohnS_3CX!

Thanks a lot for the clarifications. I will try to contact them and see what is going on and why we have these failures with registrations.

Have a great day!

Sure thing, let us know how it goes and we can troubleshoot accordingly

Hi,

We released an update which should resolve an issue with registration:
https://www.3cx.com/blog/releases/v16-update-6a/

Please check it out and confirm whether it resolved the issues you were facing or not.
