Q
What is a Cisco Unified CM Device License?
A
A Cisco Unified Communications Manager Device License authorizes IP phones, video endpoints, and gateways to register with and use CUCM features.
Q
How do I choose the right Cisco Unified CM Device License type?
A
Evaluate your deployment size and feature requirements; select Permanent licenses for production use and Evaluation licenses for 60 days of full-feature testing.
Q
What is the difference between Permanent and Evaluation Cisco Unified CM Device Licenses?
A
Permanent licenses grant perpetual device registration rights, while Evaluation licenses expire after 60 days of full functionality.
Q
How do I apply a new Cisco Unified CM Device License?
A
Register CUCM with the Cisco Smart Software Manager, import your license entitlement, allocate it to your cluster, and synchronize to activate devices.
Q
Can I upgrade an Evaluation Cisco Unified CM Device License to a Permanent license?
A
Yes – redeem a Permanent license PAK in Cisco Smart Software Manager, allocate it to your CUCM cluster, and devices convert automatically upon synchronization.
Q
How many devices can a Cisco Unified CM Device License support?
A
Each Device License covers one endpoint; your CUCM cluster can support as many devices as you have licenses allocated.
Q
What happens if I exceed my Cisco Unified CM Device License count?
A
CUCM will block additional endpoint registrations and generate license-violation alerts until you purchase and allocate more Device Licenses.
Q
How do I monitor Cisco Unified CM Device License usage?
A
Use Cisco Smart Software Manager or the CUCM System > Licensing > License Usage Report to view real-time endpoint counts and license consumption.
Q
Can I transfer Cisco Unified CM Device Licenses between clusters?
A
Yes – deallocate licenses from one CUCM cluster in Smart Software Manager and reallocate them to another cluster via your Smart Account portal.
Q
How do I renew or extend an expiring Cisco Unified CM Device License?
A
Redeem a new PAK or subscription entitlement in Cisco Smart Software Manager, allocate it to your CUCM cluster, and synchronize to update expiration dates.
Q
How does Cisco Smart Licensing work with CUCM Device Licenses?
A
Smart Licensing centralizes entitlements in Cisco Smart Software Manager, automates usage tracking, and enables allocation of CUCM Device Licenses via token-based registration.
Q
Are there license requirements for virtualized Cisco Unified CM deployments?
A
Virtualized CUCM uses the same Device License model as physical deployments and requires Smart Licensing registration for entitlement tracking.
Q
What are the steps to troubleshoot Cisco Unified CM Device Licensing errors?
A
Verify Smart Software Manager connectivity, ensure correct Smart Account mappings, confirm PAK redemption, and review license usage in CUCM’s License Usage Report.
Q
How do I order additional Cisco Unified CM Device Licenses?
A
Purchase through a Cisco reseller or Commerce Workspace, obtain a new PAK, redeem it in Smart Software Manager, and allocate the licenses to your CUCM cluster.
Q
How does high-availability affect Cisco Unified CM Device Licensing?
A
In a high-availability CUCM cluster, Device Licenses are pooled across publisher and subscribers; you must cover the total endpoint count cluster-wide.
Q
What is license reservation for core devices in Cisco Unified CM?
A
License Reservation sets aside a fixed number of Device Licenses for key endpoints (e.g. gateways, SRST) to ensure registration during Smart Licensing outages.
