Hi
3Cx V18 Update 5 (build 418) running on a Windows Server 2019 Standard box on prem (well actually in a data centre 5 miles away)
This morning out of the blue we lost all external calls, both incoming and outgoing. Nothing has changed our end. We have checked with Gamma, our sip provider and they say there is no problem their end.
We have full internet connectivity, we can ping our sip provider, there are no firewall issues.
Internal calls are not affected. the 3CX app is working ok but again only for internal calls.
I cannot see any obvious fault anywhere.
Oddly, I can dial my mobile phone from my 3CX extension, my mobile rings, but when I answer it, no audio, and my 3CX extension looks as if it's still waiting for the call to be answered.
The log shows the call attempt but just says call ended.
IS there anything obvious to check first off? This is doing my head in as nothing looks wrong.
I have a support zip file I can dropbox if anyone want a look
