It appears that RPM requires registration to an H.323 gatekeeper in order to place an H.323 call. How do we get feature requests to Polycom such as support of ANNEX-O (URL) dialing which does not require registration to a gatekeeper?
The feature request link is on this page:

I've opened Feature Request EXT-4632 for this. We'll see if/when it gets accepted/implemented.
