Disabling asterisk sip user

Question

I need to temporarily disable a sip user from registering to my asterisk server. Is there any other way to do that apart from deleting it? Thank you very much.

Answer 1

in sip.conf add following lines in user's category

deny=0.0.0.0/0.0.0.0
permit=

Answer 2

Simplest variant - just change password to other or add

host=127.0.0.1

(change dynamic to 127.0.0.1, so registration allowed only from localhost).
