A customer was upgraded to the 8.1 Software Pak and now the spa525g phones send a beep to an outside caller when the mute button is pressed. How do you turn that off? Where is the release note that describes this change?
Are your SPA525g's running 7.4.6 firmware by chance? We noticed this as well on ours (7.4.6 comes with the 8.1 software pack). There is another update to 7.4.7 firmware for the phones and we are no longer having this issue, give it a try and see if it fixes it for you.
