CB Test *888 not working

[FragFranz]

Hy,
on our installation *777 is working fine - only one caller possible
CB Test *888 was working when we started.
when I now dial *888 I hear the message "busy"

I never get a callback. 1-2 Minutes later I get a notification mail "
You missed a call:
From: Ext.*888

To: my number

Received: "Wednesday, March 29, 2023 2:06:31 PM"

Ringing: "00:00"

I can provide a pcap file

Regarding your question, within the management console, navigate to Settings > General tab, uncheck the option 'Play Busy prompt when the extension is busy,' then press Ok and try dialing *888 again.
