i don't remember i have proposed saying something about an entity (UA)
not supporting the spec.  what i have proposed is that an UA supporting
the keep spec should still send CRLFs even it does not get back
keep=yes.

i still don't understand why we need an addition to sip protocol for
CRLFs keepalives.

why can't you instead say in your draft that before sending a register
or any other sip request, UA sends double-CRLF to find out if ob proxy
supports CRLF keepalives.  it does, if UA gets back a single-CRLF and
otherwise not.  

in my opinion, it would be much simpler than inventing yet another
addition to sip protocol on top to the countless additions there already
exists and that no-one has implemented.
