Caller ID
If you try to save a caller ID history entry to the directory without a number, UNABLE TO SAVE
displays.
If the telephone number has more than 15 digits, only the last 15 digits appear in the caller ID
history. The telephone can still save all digits (up to 24 digits) of that telephone number from
the caller ID history in the directory.
You might need to change how a caller ID number is saved in the directory if the entry does not
appear in the correct format. Caller ID numbers might appear with an area code that might not
be necessary for local calls, or without a 1 that might be necessary for long distance calls. For
details, see To view the dialing options on page 34.
