On incoming calls there is a ringing shrill in the background.
I'm using a Jabra 6430 headset.
I'm using the newest test firmware.
Just to clarify. While I'm on the call I can continually here the shrill in the background.
Sorry for the delay. I would recommend to try our latest firmware release: https://service.snom.com/display/wiki/Deskphones+Firmware
If you still have problems, it might be better to use one of the headsets on our supported list: https://service.snom.com/display/wiki/Supported+Headsets
I'm experiencing the same error. I'm on snomD385-SIP 10.1.41.1.
Unfortunately, we still only support the headsets in this list: https://service.snom.com/display/wiki/Supported+Headsets
I am sorry for the inconvenience.
