Just install 500 cupc clients and in the process I ran into a few issues that resulted in what you are experiancing:
here goes:
in call manager
1. make sure user has licensing enaabled under capabilities assignment"no brainer but just in case"
2. build the cup phone and make sure the device name after upc does not exceed 12 charecters and all capitals letters
3. set device pool of cupc to be the same as hard phone
4.associate the owner user id to the user
5.associate the primary phone of the user
note, allow control of cti should not be checked here
6.associate digest user
save and click ok on pop-up
click add a new extension
enter directory number and route partiton
note, allow control of device from cti must be checked here
7. click associate end userbutton and chose user.
save
under user management
1. find or add the user under end user
click the device association button
find desk and cupc phone and associate.
save
click go to go back to users page
select the subscribe calling search space " recommended setting would be internal css
check the allow control of device from cti
select the correct "primary extension from the dropdown"
click the add to users button
find and check the standard cti enabled
click the add selected button
save
on the presence server under user settings
use drop down to select the following
prefeerred cti device
unity profile
meetingplace profile
device pool
ldap profile
sip proxy profile
save
couple of things
1. name for user must be the same as ldap
2. mac address of cti device in cupc must match the users
3. the 12 char name thing very important.
hope this helps.
