For some time now, I've had a telephone landline problem: When I call someone, the person called doesn't hear me.
I can hear him perfectly!

I run a Fritzbox 7590 as a router behind a Huawei Booster DN9245X6-10.
The phone on this 7590 has already worked properly some weeks ago.


Has somebody any help-idea?

Sorry when i am wrong in this forum
