Outgoing phone calls are no longer possible [landline / germany]

Hello!
I use the tp-link VR900v as a router (Germany, provider Telekom). A landline DECT telephone is connected to the router (Siemens Gigaset C620).
Has been running flawlessly for years, and even now Internet/DSL and incoming calls are possible without any problems. But for a few days no outgoing calls are possible.
After typing any phone number, an automatic voice comes: "The command is unknown. Please correct the input." (of course in German). In the call log in the router menu there is only "*31#" as dialed phone numbers (code for temporary number suppression, but I didn't dialed that code).
As I said, the problem has only been on for a few days and I haven't changed anything in the configuration of the router or telephone! In the router menu is no calls rule and none
call forwarding entered; "Call Through" is disabled.
Does anyone have an idea how this comes about? Where can I change this?
