Which two parameters are requested in an Audit Connection message from a Cisco Unified CM to endpoint on a MGCP gateway? (Choose two)
In a Media Gateway Control Protocol (MGCP) call flow, the Audit Connection message is used by Cisco Unified Communications Manager (CUCM) to request information about an existing connection on a MGCP gateway. This message is sent to an endpoint on the MGCP gateway, such as a digital signal processor (DSP) or a voice port, to gather specific information about the connection. The message is used to ensure that CUCM and the MGCP gateway have consistent information about the call, and to verify that the call is still active.
The two parameters that are requested in an Audit Connection message are:
Call ID: This is a unique identifier for the call that is used to match the connection on the MGCP gateway with the call information in CUCM. The Call ID is typically a numeric value that is assigned by CUCM when the call is established.
Connection ID: This is a unique identifier for the connection on the MGCP gateway that is associated with the call. The Connection ID is typically a string that is generated by the MGCP gateway when the connection is established. The Connection ID is used by CUCM to identify the specific connection on the MGCP gateway that is associated with the call.
The other parameters listed in the answer choices are not typically requested in an Audit Connection message. Here is a brief explanation of each parameter:
B. Capabilities: This refers to the media capabilities of the endpoint, such as the codecs and protocols that it supports. This information is typically exchanged during the endpoint registration process.
C. Bearer Information: This refers to the type of circuit or channel used for the call, such as analog, digital, or VoIP. This information is typically negotiated during the call setup process.
D. Connection Parameters: This refers to additional information about the connection, such as the packetization period or jitter buffer size. This information is typically negotiated during the call setup process.
E. Connection Mode: This refers to the type of connection mode used for the call, such as unicast or multicast. This information is typically negotiated during the call setup process.
F. Connection ID: This is a duplicate answer choice and is already discussed above.
