yes, but it's not as simple as just export in one and import in another. the fields between versions are different so you need to adjust the files manually to match required fields

Active Directory or would work, but it sucks in 4.x and very the schema updates are horrible.

You can do the following:

Export the users from each CUCM

open each into CSV

Leave the headers intact in each column

copy and paste the similar fields to/from each csv.

upload back to their respective cluster.

Eventually, you will want to have some sort of common directory. Even it's homemade directory through XML. You can re-direct the Directories to a different source and pull from there. (which would be where you merge all your exported users from each cluster) Trick is, you have to create that piece... granted it takes time, but how much does it take to update the directory every week or month on all clusters.

In the CallManager SDK there is a sample phone service that can search multiple LDAP directories and return all matching results.

It is an ASP service and so requires an IIS server. I am web server expert but managed to get it working in a couple of hours.

The SDK can be obtained from the link below. I have attached the ASP file for your reference. You do need the LDAP DCOM dll from the SDK to use it.

Please rate if helpful.

Just read that you have 6.x so there is no LDAP for that release.

Best solution would be to add phone numbers to AD (assuming that it services all three organisations) and then set up an ASP phone service to query AD for phone number.

You can still use the ASP file from my last post - just point it to AD instead.
