Idea

Are you referring to On-Demand Call Recording? If so, the DTMF tones when you activate the recording will be heard by both you and the other party. There would be no way RingCentral would be able to stop that from occurring.

If that's not what you are referring to, could you be a little more specific?

could this be determined by what state they're in and having to notify each party a call is being recorded? if its just listening in on a call a barge / listen feature shouldnt make a noise, unless theres no way to do it without the dial code.

No...there would be too many variables based on which state the caller or the called party are in.

Again, are you referring to the tones you hear when you press *9 to begin/end an On-Demand recording session?

I am not referring to on-demand recording. As I wrote in first message this idea/request related to using feature code *80. This feature code initiate Call Monitoring feature described on this page:  https://support.ringcentral.com/s/article/8086?language=en_US

When someone dials this feature and enter extension number, there is beep sound played. Idea is in having option to disable this sound. In our case it'll help to get better speech recognition of monitored call.

LLC,

I'm sorry...I don't know how I missed that. However the answer is still the same. Whenever you press keys on your telephone you will get DTMF tones. DTMF is an in-band telecommunication signaling system which uses the voice-frequency band over telephone lines between your phone and other communications devices, applications, etc. This is how the feature in the application knows when to start/end. It "hears" the tones, which would be different than *67 tones or any other tones. Essentially, if you take away the tones you take away the feature.
