I've off and on thought about this, and the comments about how no known
phone right now is RFC compliant. The comments have said that there are
a couple of different ways of signaling the different rings.

This brings me to the idea that could potentially bring the dial command
back to something usable just like the zapata way. Could you not make
ring definitions on a per sip user basis and reference them with a
number just like the way we do with zapata? Maybe in a homogeneous SIP
device environment you could define the distinctive rings in the general
section, but in a heterogeneous environment the ability to set the rings
local to the user/phone would eliminate the problem of the RFC says to
provide a URL, but cisco says an integer is enough.

I'll admit I don't have enough knowledge of how SIP works to do any more
than suggest this to those who may make the changes.
