Software agents perform a process to monitor the availability and/or performance of various functions of a messaging system. A call is initiated to an endpoint, where the endpoint is registered with a messaging system and is configured to forward incoming messages to the messaging system. A first agent transmits a message to the endpoint for forwarding to the messaging system. A second agent determines whether the endpoint receives a message notification. In an embodiment, the time that elapses between arrival of the message at the endpoint and reception of a message notification is determined. In an embodiment, if the second agent is able to retrieve the transmitted message, then the retrieved message is compared with the version of the original message that was received at the endpoint. Whether the retrieved message suffered any degradation from its path through the messaging system is determined based on the comparison.

Method and apparatus for measuring health and performance of a messaging system

Software agents perform a process to monitor the availability and/or performance of various functions of a messaging system, such as a Unified Messaging System. A call is initiated to an endpoint, where the endpoint is registered with a messaging system and is configured to forward incoming messages to the messaging system. A first agent transmits a message to the endpoint for forwarding to the messaging system. A second agent that is associated with the endpoint then determines whether the endpoint receives a message notification in response to the transmitted message. In an embodiment, the time that elapses between arrival of the message at the endpoint and reception of a message notification is determined. In an embodiment, if the second agent is able to access a mailbox and retrieve the transmitted message, then the message retrieved from the messaging system is compared with the version of the original message that was received at the endpoint. Whether the retrieved message suffered any degradation from its path through the messaging system is determined based on the comparison.

A test emergency response location (ERL) is used to exercise an emergency response (ER) service. The test ERL does not have any connections to the real external PSAP or OSAN and only routes the call to synthetic phones or agents. A 911 call is intercepted and routed to an ER application to make a decision on which emergency location identification number (ELIN) to use. The ER application recognizes the call originator as a synthetic phone or agent and routes it through the test ERL. In one embodiment, the test ERL is configured so that a second synthetic phone or agent is registered as the PSAP endpoint and a third synthetic phone or agent is registered as the OSAN endpoint. In a properly functioning system, the ER application forwards the call to the second and third agents. When the second and third agents receive the calls, the system is considered to be functioning properly.
