Can you apply a filter to an empty field in Active Directory with CUCM?

Hi Team

I filter users while IpPhone field is different from emptiness, such as the filtering?

                                    ! (ipPhone = null)?

Is it more advisable to have the field to zero and let the filter like this:! (ipPhone = 0)?

Thank you

If this filter works for you it is perfectly fine then, I would not worry about hard coding the field to 0 or anything else that does not make sense.

Hi Chris

I can use the command ldapsearch in the Active Directory for test the filter,

Is it right to the filter :   !(ipPhone=null) ?

Thank you

Yesenia,

The actual meaning of this filter is this "dont import any user with ipphone field = null"

Hi aokanlawon

Then with "null" if I can indicate empty, is that correct?

Thank you

A simple and effective filter to use is this..

(ipPhone=*)

This will allow CUCM to import only users with valid entries in their IP phone field. I think its much better
