[asterisk-users] deny=0.0.0.0.0/0.0.0.0.0 does not seem to block external access

[Eric Smith]

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?
