Hello shabana,
welcome to the Polycom Community.
To my knowledge only the Polycom® VVX® 1500 C is officially supported on the Cisco CUCM Platform.
Your Polycom® VVX® 1500 D may work as a 3rd Party Sip Device and supports the following:
Corporate Directory—The phone can be configured to access your corporate directory if it has a standard LDAP interface.
This feature is part of the Productivity Suite. Active Directory, OpenLDAP, Microsoft ADAM, and SunLDAP are currently supported.
The VVX1500D does not require an addition Productivity Suite license to utilize Corporate Directory access.
If your CUCM is compatible with the above please check the Admin Guide => here <= (assuming you are running UCS 3.3.0 or later) and check this Document at the Feature Descriptions & Technical Notifications => here <=.
Another method could be to utilize the Local Contact Directory—The phone maintains a local contact directory that can be downloaded from the provisioning server and edited locally.
Any edits to the Contact Directory made on the phone are saved to the provisioning server as a backup.
For further support please liaise with your Polycom Reseller and/or Polycom Support.
Best Regards
Steffen Baier
Polycom Global Services

The title Polycom Employee & Community Manager is a community setting and does not reflect my role. I am just a simple volunteer in the community like everybody else. My official "day" Job is 3rd Level support at Poly but I am unable to provide official support via the community.
