we have just installed CUPC8.0 and the users have Outlook 2007. we would like to ne able to use the IM and call features within Outlook 2007. but from several hours of testing it looks like the users login name for the phone has to be the same as the users email addrerss for the Presence to be displayed and the Call and IM features to work. This is fine but with users logging in and out of the phones on a daily basis it will take a considerable amount of time to log into the phone using thier first name and last name. is there a way round this ? our system is not intergrated with AD via LDAP. would this resolve the issue ? as both systems seem a bit disjointed.
