In section 6.1.5 of the sip-h323-interworking spec, there is a sentence: "The IWF SHOULD be able to map the common audio, video and application format names supported in H.323 to and from the equivalent RTP/AVP [RFC3550] names." It is good practice to always mention how the three main media of video, audio and text shall be handled in real time applications. audio and video are mentioned explicitly. It may not be evident to everybody that real time interactive text is capability declared in H.323 Annex G / H.245 by DataApplicationCapability.application = t140 So, in fact it is covered in the sentence requiring that "application" format namnes shall be mapped. The mapping should correspond to the RTP/AVP name text/t140 and corresponding names for inclusion of protection against loss. I seek your guidance how it can be made more clear that "text" capabilities can be expressed in both H.323 and SIP systems and should be mapped.
