Problem with ring-group, it is like immediate end call, not sure

[joe-3cx-user]

Hello,

Call from Customer today: Ring Group 300 (5 Members) has busy tone for incoming callers.
She said it looks like one telephone is blinking short or something like that.
It was working last week and it was created some month ago.
Activity Log shows below story if I do a test call.
+49160 is the incoming test caller.

There is something different with the 310..below, but I don´t know what that means.
310 is the TOP1 Member of Ringgroup 300 - but ringing strategy is ring all.
Destination if no answer is -> end call. (I think it is the busy tone, not sure..)
I didn´t tried to delete 310 from the group yet.
Caller-Log shows "not answered"
If I go to destinations and check status of every ring-group-member it shows "available"

The Log has better layout on this etherpad: https://etherpad.netluchs.de/p/3cx-question

Hello @joe-3cx-user

Try removing extension 320 from the Ring group as it seems the error is coming from that extension and see if that works. Check if the extension has forwarding enabled on the device or in the forwarding rules that could cause the issue.
