hello to you guys, after i installed the last stock items of officeserv system at home, including wifi and mobile.
Today I became aware of something that I had never noticed before.
All smt-i5243 have a continuous quiet noise in the speaker, I tested an SMT-i6010, everything is quiet there.
Since the devices 5243 and 5230 support audio duplex, the question now is whether the noise comes from the additional audio duplex chipset.
In the Rel. Notes of the SMT-i5230 I think something with in the speaker noise appeared.

Does anyone have experience of whether the SMT-i5343 also constantly noise in the speaker? Otherwise I would get one for the bedroom.
