I'm new. I just want to know what setting to change if someone is telling me their 7975 and 8851 phones ring when already on a call. I checked line 1 and it shows flash only when phone is active.</P> Thu, 12 Aug 2021 20:21:05 GMT https://community.cisco.com/t5/voice-over-ip/7975-and-8851-phones-ring-out-loud-when-on-a-call/m-p/4448662#M14092 Syllinx 2021-08-12T20:21:05Z https://community.cisco.com/t5/voice-over-ip/7975-and-8851-phones-ring-out-loud-when-on-a-call/m-p/4534905#M14113 <P>Hi, very strange behaviour.<BR />Check if there is only one extension configured on this phone and try to disable call waiting or set the busy state on 1 call.<BR /><BR />Regards.</P> Thu, 20 Jan 2022 08:18:23 GMT https://community.cisco.com/t5/voice-over-ip/7975-and-8851-phones-ring-out-loud-when-on-a-call/m-p/4534905#M14113 Daniele Giordano 2022-01-20T08:18:23Z
