Isn't that a problem with the SIP URI? If I was making up a URI scheme
and these things were important, I'd probably include them. If I don't,
it probably means use whatever my device can do that the other end
supports, maybe tending towards the highest fidelity.

I don't know about SIP specifically - what does the description of the
SIP URI scheme say about this?
