[Asterisk-Users] caching of sip account

[Mimmus]

Hi,
during tests, I configured different SIP accounts on the same phone. 
Now I see this 'sip show peers output':
 Name/username  Host        Dyn Nat ACL Port     Status   
 259/259        10.97.1.19   D  5060             OK (8 ms) 
 232/232        10.97.1.19   D  5060             OK (7 ms) 
where both extensions are registered and have the same IP.
But now I have only one extension configured on the phone!
How can I remove/reset previous registration?
