we have new C520 WiMi and after a little testing we found the quality that receives at a caller is very bad.
What comes out of the SNOM´s speaker is loud and clear, very fine. But what arrives at the caller is kind of weak and tinny. Not what we expect.
So, is there a way to configure the microphones to be more powerful and understandable voices at the other side? We´re not satisfied about that.
Thanks for helping a with best regards
