CISCO-VOICE-CONNECTIVITY-MIB
AI MIB Summary
The CISCO-VOICE-CONNECTIVITY-MIB monitors registration states (registered, unregistered, rejected) and connectivity status between Cisco voice gateways, IP phones, and call processing agents across H.323, SIP, MGCP, SCCP, and SGCP protocols. It enables network management systems to retrieve real-time port-level registration data and verify the operational link between voice endpoints and their associated call agents.
This MIB module provides connectivity related information for devices (e.g., 'connectivity between voice gateway, phones, gatekeepers and call processing agent'). The MIB can be used by network management applications to collect the information regarding voice connectivity among the devices in the network. The MIB can also be used to retrieve the status of voice connectivity between the devices.

CALL AGENT A call processing agent component of a device in IP telephony and VoIP network.
PORT A port on the device that is associated with call processing agent.
REGISTRATION In an IP telephony network, there are typically keep- alive messages or expected registration refresh timers that are used to formulate the registration status of devices and/or users. Possible values of the registration status are as
follows:
registered: The port has successfully registered with
the call agent
unregistered: The port is no longer registered with the
call agent
rejected: Registration request from the port was
rejected by the call agent.

CALL AGENT
A call processing agent component of a device in IP
telephony and VoIP network.
PORT
A port on the device that is associated with call
processing agent.
REGISTRATION
In an IP telephony network, there are typically keep-
alive messages or expected registration refresh timers
that are used to formulate the registration status of
devices and/or users.
Possible values of the registration status are as
follows:
registered: The port has successfully registered with
the call agent
unregistered: The port is no longer registered with the
call agent
rejected: Registration request from the port was
rejected by the call agent. MODULE-IDENTITY .1.3.6.1.4.1.9.9.393 |
ciscoVoiceConnectivityMIBNotifs OBJECT IDENTIFIER .1.3.6.1.4.1.9.9.393.0 |
cvcPortRegistrationStatusChangeA cvcPortRegistrationStatusChange notification is generated
when the value of cvcRegistrationStatus changes. It can be
utilized by an NMS to get current registration status change
information. cvcPortDeviceName and cvcCallAgentInetAddress can
be used by NMS to get information about the port and
call agent from cvcPortTable and cvcCallAgentTable
respectively.
An NMS should periodically check the value of
cvcLastStatusChangeTime to detect any missed
cvcPortRegistrationStatusChange notification-events due to
network problem or any other problem. NOTIFICATION-TYPE .1.3.6.1.4.1.9.9.393.0.1 |

cvcCallAgentTableThis table contains information about call agents.
When the network management subsystem implements this MIB, this
table lists the call agents that exist in this system.
This table will contain one entry per call agent.
When systems other than those hosting call agents implement this
MIB, this table will contain the list of call agents to which ports
of this system are associated. The entries would be representative
of remote call agents.
For example, if a device is a voice gateway having a T1 port
associated with three call processing agents, then this table
will have three entries representing each of the three call
processing agents.
The network management subsystem adds conceptual rows to this table
for every call agent. SEQUENCE OF CvcCallAgentEntry .1.3.6.1.4.1.9.9.393.1.1.1 |

another MIB group. This can be used to get more information
about the port defined in other MIB group. For example, to get
more information about the T1 port defined in this table, this

cvcCallAgentPriorityA port can be associated with multiple call agents. In case
of failure of the call agent to which the port has been
registered, port falls back to the back-up call agent. To
achieve this redundancy each call agent is assigned a priority
number in context of port. This object indicates the call
agent's priority number.ro Unsigned32 .1.3.6.1.4.1.9.9.393.1.3.1.1.1 |
