reregistration a Cisco ip phone

[mojtaba961]

hi,

i have 7941 ip phone,somehow i delete it from the call manager8 by mistake and when i tried to add it again it gives me this message:

Add failed. One of the required fields on the page has the same value as an entry that already exists in the database. Please check the corresponding Find List page to verify your entry does not exist.

i don't know how can i solve this problem,

thank in advance.

it sounds like the phone is still configured in the database. search by MAC address and you'll find it.
Did you delete the phone or just the DN that appeared on the phone?

yes i think kind of it is still configured in database. i searched by MAC address but it doesn't find that,
i deleted the phone not DN.

thank you
