Does H323 support the transfer of OLI or information digits? If so, what ITU spec states this?

Certain ISUP parameters were not mapped directly into H.323. Cisco initiated some work a few years ago and it transmits such parameters as 'GTD' (Generic Transparency Descriptor) parameters. GTD was taken to the ITU and standardized as NSS (Narrowband Signaling Syntax) Q.1980.1. H.323 Annex M4 describes the transport of NSS within H.323.
