What is rtpOnlyModeForTrunkRtpOnlyModeForTrunk?

This OID controls RTP channel behavior for trunks, with values selecting full duplex, transmit-only, receive-only, or default modes. Engineers set this to optimize audio paths in asymmetrical network conditions or when one direction is already handled. Value 1 opens bidirectional RTP; value 2 opens RTP for transmission only.
