THen you need to check the parameters to the save() command on the same documentation page:
"
0x04 - store and maintain one contact per AoR. If there are other contact addresses for AoR not matching current registration, remove them. This mode ensures one contact per AoR (user).

I want to allow the user to register again, deregistering the oldest contact.
