The Cisco AnyConnect works well, until the user tries to place a VoIP call using the Cisco IP Communicator. Looking at the event logs, these two entries stand out:
Function: flushNetworkBio Return code: 0xFE1F0013 File: .\TlsProtocol.cpp Line: 449 Description: SOCKETTRANSPORT_ERROR_MAX_WRITES
A DTLS Alert was sent by the client during a write operation. Severity: warning Description: close notify.
Any thoughts as the cause?
