Appendix B: Enterprise Voice-Related Performance Counters
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
Office Communications Server provides performance counters that you can use with Performance Monitor to identify a failure that may require troubleshooting. The following table describes Office Communications Server performance counters that can indicate configuration issues which can affect Enterprise Voice calls.
For details about using Performance Monitor, see Perfmon at Microsoft TechNet at https://go.microsoft.com/fwlink/?LinkId=143009.
Table 10. Performance counters that can indicate Enterprise Voice issues
| Issue | Troubleshooting Process |
|---|---|
NUM_EXUM_TIMEOUT_OR_FAILURE |
Indicates timeouts or failures experienced when routing a call to ExUM. See Troubleshooting Network Issues with Exchange Unified Messaging. |
NUMFAILEDOUTBOUNDCALLS |
Is incremented when an outbound Office Communications Server to PSTN/PBX call fails. The failure can be caused by a variety of reasons, such as a configuration error or network connectivity problem. See Troubleshooting General Network Issues. |
NUM_INVALID_LOCATION_PROFILE |
Is incremented when Office Communications Server receives an INVITE with a phone-context parameter that references an incorrectly formatted or unknown location profile. See Creating and Configuring Location Profiles in the Administering Office Communications Server 2007 R2 documentation. |
NUM_NOMATCH_RULES_IN_LOCATION_PROFILE |
Indicates that a user dialed a number for which a corresponding normalization rule does not exist in the location profile. See Creating and Configuring Location Profiles in the Administering Office Communications Server 2007 R2 documentation. |
NUM_RECEIVE_5XX_FROM_VoIP_GATEWAY |
Is incremented when a Mediation Server or gateway sends a 5xx response to an INVITE. It indicates the inability of the Mediation Server or gateways inability to handle the call due to an overload or other error (related to event 46026). See Outbound Routing Events Related to Enterprise Voice. |
NUM_CALLS_DENIED_NO_GATEWAY |
This counter is incremented when a route is chosen for a call, but the gateway list is empty (related to event 46017) |
NUM_CALLS_DENIED_NO_ROUTE |
