ist there any way to get rid of this permanent dizzy noise? IP phone is connected to local asterisk server, calls are going through SIP provider, codec g711u. Other equipment even dect phones (over sip-adapter) have no such effect, so it's phone related. It's not loud, but if you know about it - it's there and really annoying.
Silence support is disabled. Decreasing handset volume does help, but not really a solution for normal working environment.
Thanks a lot.
