asterisk users - Oct 2012 - deny=0.0.0.0.0/0.0.0.0.0 does not seem to block external access

I have the following in sip.conf for asterisk running on localhost.

deny=0.0.0.0/0.0.0.0
permit=127.0.0.1/255.255.255.255

However, there is still repeated ill-intentioned access in this form:
NOTICE[17550]: chan_sip.c:14847 handle_request_invite: Call from '' to
extension '700972595637212' rejected because extension not found.

I am running an ancient Asterisk 1.4.26.2 (yes I know what I should be doing).

Why might the deny not be working?

You do not have an exten => 700972595637212 in the context in extensions.conf
that SIP device is set to in sip.conf

Really on localhost only, no peers other than from 127.0.0.1? Not sure 
why deny/permit is not working, but you could do
bindaddr=127.0.0.1
in your sip.conf.
