What is acRtpComfortNoiseEnable?
This OID enables or disables RFC 3389 Silence Indicator (SID) packets that simulate background noise during voice call silence periods. Engineers enable this to improve call quality perception by eliminating the dead-air effect, especially on lower-bandwidth networks. Setting it to 1 causes the gateway to send comfort noise packets every 160ms during silent intervals.
