|Message:||The VoIP platform encountered an exception %1 during the call with ID “%2”. This exception occurred at the Microsoft Exchange Speech Engine VoIP platform during an event-based asynchronous operation submitted by the Unified Messaging server. The Unified Messaging server will attempt to recover from this exception. If this warning occurs frequently, contact Microsoft Product Support.|
This Warning event indicates that an exception occurred at the Microsoft® Exchange Speech Engine Voice over IP (VoIP) platform during an event-based asynchronous operation submitted by a computer that has the Unified Messaging server role installed. Event-based asynchronous operations allow the Unified Messaging (UM) server to continue to accept new calls and wait for responses for previous calls at the same time. The UM server handles these parallel VoIP operations by using separate threads. These parallel operations allow the UM server to perform many tasks at the same time, yet remain responsive.
If this warning frequently occurs, contact Microsoft Product Support. For information, see the Microsoft Help and Support Web site.
