Hello,
I'm configuring a SPA301 for a workspace where there is a lot of noise, so I push the ringer volume to it's maximum.
After to have make a test to hear the ring of this phone (without answering) I heard a strange noise, like the noise of the wind.
In fact I can hear the noise all the time after a missed call, but higher the ringer volume is, higher I can hear it.
The only way to "remove" this noise is to hang-up / hang-down.
