Solved Raspberry pi no accessible and SBC SIP trunk down

[yoursmartgecko]

Hi There,

We've noticed that our SBC SIP trunk went down. We tried to access our Raspberry pi but it won't let us in. I am having a "connection refused" error when using Putty.
On the Yealink phone there is "Warning no service" error. Could you please advise?

Thanks,

Try to reboot the PI, it may be locked up.

You pretty much figured it out, you just need to troubleshoot the Pi.

If you cannot recover it, make a fresh SD card and start from scratch:

Thank you both. We will make a fresh SD card.

Making a fresh SD card fixed the problem. Thanks.

Glad to hear! Sometimes SD cards will eventually fail but they are easy to replace and very affordable.
