What is sipMiscComfortNoiseNegotiation?

This OID controls whether the gateway negotiates comfort noise (CN) payloads in RTP to avoid silent gaps in calls. Operators enable this for better perceived audio quality during silence periods in VoIP calls. With CN negotiation active, peers use an agreed-upon codec for background noise instead of complete silence.
