Cisco E3C-U-TN EA3 Local Telephone Number Service

Add a local telephone-number service component to a Cisco EA3 Collaboration environment where a local TN service option is required. This entitlement addresses the telephone-number layer of a calling deployment rather than supplying a handset, gateway, switch, or other installed hardware. Its scope is local telephone-number service, helping administrators distinguish number-related service requirements from user endpoints and calling infrastructure. E3C-U-TN is specified for an uncommitted local telephone-number option. The uncommitted designation is important when matching the service requirement to the intended Cisco EA3 Collaboration configuration. Buyers should treat the local TN description as the defining service characteristic and ensure that their planned calling environment has the associated Cisco collaboration services required to support telephone-number use. This item fits deployments that need a local-number service element as part of a broader collaboration and calling design. It does not describe a phone number itself, a geographic location, a numbering plan, porting activity, emergency-calling coverage, or a physical product. Those elements depend on the wider service configuration and deployment location. Select it when the required service component is specifically an EA3 local telephone number with the uncommitted option.
