ABSTRACT:
An apparatus, system, and method are disclosed for validating application server replication errors. The method includes receiving a first information message with a test sequence from a caller. The caller is engaged in a communication session with a callee according to a communication protocol and the communication session is managed by a first application server. The method also includes storing the test sequence in a replicable data structure on the first application server. The replicable data structure is replicated to a second application server to form a replicated data structure and both servers operate within an active-active configuration. The method also includes receiving a second information message from the caller. The second information message includes a confirmation sequence. In addition, the method includes determining a replication error in response to comparing the stored test sequence in the replicated data structure with the confirmation sequence.
