The Peripheral Gateway (PG) communicates with CUCM using the JTAPI protocol. The JTAPI client software installed on the PG server must be compatible with the version of CUCM. A version mismatch can lead to communication failures, including the inability to control agent devices, resulting in login failures. The resolution is to download the correct JTAPI client from the CUCM administration plugins page, install it on the PG, and restart the PG process to use the new client.

To pass data from an ICM script to a CVP VXML application, you must use Expanded Call Context (ECC) variables. You define an ECC variable in ICM (e.g., user.caller.name) and use a 'Set Variable' node to map Call.PeripheralVariable1 to it. In the 'Send to VRU' node, you specify that this ECC variable should be sent. CVP then makes this variable available to the VXML application, where it can be accessed within the session data (e.g., session.id.user.caller.name).

A unique name for the site is a fundamental and required piece of information for identification.

The Internal Name is a mandatory field that is used by the system internally. It must be unique across the enterprise.

Live Data provides sub-second, event-driven updates pushed directly from the CTI Server via a WebSocket connection. CUIC real-time reports, by contrast, poll the database at a configured interval (typically 15 seconds or more). This difference in data retrieval mechanisms means Live Data reflects the absolute current state, while the CUIC report reflects the state at the last polling interval, often causing a slight lag and discrepancy in highly dynamic values like calls in queue.

The utils diagnostic_framework enable command is used in the Unified System CLI to activate the Diagnostic Framework services, including the Portico web interface, allowing administrators to access deep tracing and logging capabilities.

For call context data to be preserved and passed during a blind transfer or consult transfer initiated from a CTI application like Finesse, the User-to-User Information (UUI) field in the SIP header is often used. The Cisco CTIManager service on CUCM has a specific service parameter, 'Send UUI Data for CTI-Initiated Transfers', which must be enabled (set to True) to allow this data to be passed along with the call.

The IdS (Service Provider) must have the IdP's public certificate to validate the digital signature of the incoming SAML assertion. If this certificate is missing, expired, or incorrect in the IdS trust store, the signature validation will fail.

A mismatch in the signing algorithm (e.g., SHA-1 vs. SHA-256) between what the IdP uses to sign the assertion and what the IdS expects will cause a signature validation failure. Modern security practices require SHA-256, and if the IdP is using an older, weaker algorithm, the validation will be rejected.

The ICM Router will only match a call to agents who are in the same Media Routing Domain (MRD). Even if agents are in the correct skill group and are in a 'Ready' state, if the call's MRD (defined by the Call Type) does not match the MRD the agents are configured to handle, the router will consider them unavailable for that specific task. This is a common configuration error that separates agents and tasks into different media pools (e.g., Voice vs. Email).

False. In a standard PCCE deployment model, the CUIC Publisher and Live Data (LD) server are typically co-resident on the Side A Call Server/Router VM. The Logger database resides on the Side A Data Server VM. These are separate virtual machines in the PCCE OVA deployment.

The 'Get Queue Information' node in the ICM Script Editor is used to retrieve real-time statistics about a specified skill group or precision queue. One of the key values it can retrieve is the Estimated Wait Time (EWT), which can then be stored in a variable and used in an 'If' node to make a routing decision, such as offering a callback.
