I know over time SIP OPTIONS message handling has changed and I've seen
some write ups that seem to indicate that an s extension in the default
context is needed now to get them to work.
It's probably my error in any case.
So, what am I doing wrong or what do I need to do to get the sip ping to
work?

Just for fun, I created a sip peer called ping at a fixed address with a
default context of ping:
sip.conf
=======
[ping]
type=peer
host=XX.XX.XX.XX
defaultip=XX.XX.XX.XX
context=ping
extensions.conf
============
[ping]
exten => s,1,NoOp()
I am sending the following:
OPTIONS sip:YY.YY.YY.YY SIP/2.0
Via: SIP/2.0/UDP XX.XX.XX.XX:5061;branch=z9hG4bK1316447867

And the asterisk instance is logging the following with core set debug 9:
