Telephone System Synchronization fails with an unknown error

Article ID: 51131 - Last Review: January 15, 2013


The Telephone System Synchronization fails with an unknown error.


When executing a Telephone System Synchronization, it will get to about 95% then fail with an unknown error.  The administrative report will indicate which particular name it's failing on.

The DataSynchronization log contains the following error:

eError 1/12/2011 10:36:36 AM Unknown sync failure
--- Start Exception Stack ---
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ServiceModel.ActionNotSupportedException: The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).

eInfo 1/12/2011 10:36:37 AM Failed to sync YourSite. Trying again in 00:01:00


The Telephone System Synchronization does a regular expression like match on the names to update and brackets '( )' are special characters that needs to be treated uniquely.


Remove brackets ( ) from all devices in the telephone directory on the PBX.


CCM version 5.7
