The callbackextension is the reason this is happening.

 From sip.conf.sample:

; A similar effect can be achieved by adding a "callbackextension" 
option in a peer section.
; this is equivalent to having the following line in the general section:
;        register => username:secret at host/callbackextension
; and more readable because you don't have to write the parameters in 
two places
; (note that the "port" is ignored - this is a bug that should be fixed).

Remove that column from your table, restart Asterisk, and it should go away.
