Hello members,

I hope u can help me:
We got a CP920 which can call internal and external numbers without problems.
But calls to the phone always end up with a busy signal.
The phone then displays a missed call.
The SIP-Server (Auerswald) shows 0.01 seconds for the calls.

Firmware is uptodate

Thanks in advance for any help.
