What is h323DTMFRxDtmfOption?

This OID indicates RFC 2833 DTMF support in session descriptions for tone transmission over H.323 calls. RFC 2833 defines a standardized way to carry DTMF tones in RTP packets over IP networks. Enabling this allows tone-based systems like credit card readers to work reliably over VoIP.
