| Key 0 should always be assigned to the phone because this is the prime (user) DN ie. Key 0 MCR <ACD DN> or <Prime DN>, Key 5 MCR <ACD DN> or <Prime DN> or <alternative DN> you can also have an i2004 assigned to multiple DN's that are not associated to other users ie key 0 mcr xxxx <prime DN> marp key 1 mcr xxxx <secondary dn> marp l hope this answers your question |
