A. B. C. D. E.CE.
When manually provisioning a Cisco IP Phone 8845 using SIP, there are two fields that must be configured for a successful provision, which are:
C. SIP profile: A SIP profile defines a set of SIP parameters that are applied to an endpoint to control how it communicates. SIP profiles provide a way to specify settings for various SIP parameters, such as codecs, DTMF method, and SIP transport protocol. Therefore, configuring the correct SIP profile is crucial to ensure that the phone can communicate with other endpoints.
E. device security profile: A device security profile is a collection of security settings that are applied to an endpoint to protect it from various threats, such as eavesdropping, tampering, and hacking. Device security profiles specify settings for various security features, such as authentication, encryption, and digital certificates. Therefore, configuring the correct device security profile is important to ensure that the phone is protected from potential security breaches.
The other answer options do not relate to manual provisioning of a Cisco IP Phone 8845 using SIP in the same way as SIP profiles and device security profiles. For example:
A. Location: A location is a logical container that defines a set of common characteristics for endpoints, such as bandwidth, codec preference, and QoS settings. Locations are used to control the behavior of calls and to ensure that endpoints are configured with appropriate settings based on their location. However, locations are not directly related to manual provisioning of a phone using SIP.
B. Media resources group list: A media resources group list is a list of media resources, such as conferencing bridges, music on hold servers, and transcoders, that are assigned to an endpoint to provide additional functionality. Media resources group lists are used to ensure that endpoints have access to necessary media resources. However, media resources group lists are not directly related to manual provisioning of a phone using SIP.
D. CSS: A calling search space (CSS) is a logical container that defines a set of partitions that are accessible to an endpoint for call routing. CSSs are used to ensure that endpoints can reach appropriate destinations based on their permissions. However, CSSs are not directly related to manual provisioning of a phone using SIP.
