We are using a RingCentral recommended CyberData 011146 as the SIP paging server to integrate with our legacy paging system and amplifier.

When someone initiates a page by using the hard phone key or dialing *84, we are having volume issues.

It seems that RingCentral adds a "beep" tone at the start of the page. The beep tone that RingCentral adds is significantly louder than the speaking volume of the person announcing the page. We have struggled with normalizing the volume between speaking and the RingCentral beep through volume adjustments on the amp and in the CyberData web UI. We have not had good results.

The CyberData SIP paging server has the ability to play its own page noise or beep when a call is connected, but it does not block the incoming RingCentral beep. It is the case that we can have both the CyberData and RingCentral beep play at the same time, or we can have the RingCentral beep alone.

There appears to be no way to suppress sound for the first 0.25s of a call to block the RingCentral beep.
There appears to be no way to customize the RingCentral beep.
There appears to be no way to change the volume of the RingCentral beep.

Does anyone have any tips on how we can normalize the speaking volume of people making pages relative to the RingCentral beep tone before the page?
