Solved Low microphone volume D735

[AWS2P]

Hello,
on one customer location on Premise PBX, I have audio problems with D735 where customers get complaint from callers about low audio volume they get.

I did some internal call test and I got low volume audio, like other extension was very far . I did same test with trunk call and got same result.
On that location they have mainly D735 phones and also old Gigaset N510 DECT phones (these ones have good audio level) and they use also one App on android and it works loud and clear too.

So it seems problem is located only on D735 but these phones have no settings to increase for microphone level, do you have already got same problem?

If someone has already fixed this , i'll be happy to know how Thanks.

I opened a Snom ticket and got an answer to push a newer FW Release 10.1.193.14.
I applied the new 3CX unsupported FW and this did fix my volume problem on D735.

so if yours behave the same , apply the new FW to fix the problem
