The discovery draft is at last call, on the way to be published as an experimental protocol RFC.

[Taylor, Tom (P.T.)] [snip] Also, I read with interest ftp://ietf.org/internet-drafts/draft-ietf-svrloc-discovery-05.txt, which suggests using "Service URLs" in TXT records as a fallback when SRV lookup fails. This differs from (although it is very close to) the format of RAS information in TXT records currently contained in H.225.0v2. Of course, this is just a draft, and I have no idea how well it was received in IETF, but if it gets legs, we may want to also add support for RAS URLs in TXT records via the H.323v2 Implementor's Guide. Regardless, it would be helpful to include a pointer to this draft -- or even an H.323-specific modified version of it -- in the Implementor's Guide to help people get gatekeeper discovery via DNS correctly implemented.
