I inherited this old phone system that seems to work great except for the caller Id is only working on 3 phones out of the 9. How could I check the configuration on the ones working. I found the logical port to program and I figured out how to access the database programming and change the name, time and date. Do I check the config from each station regarding the caller id or no? What class I need to access to check the caller id being enabled on each work station not working? Any help would be appreciated.
