Procedure 2 Clearing the SMDI101 alarm

at the alarm browser

1This alarm is raised when the Simplified Message Desk Interface (SMDI) telnet session between the SIP Application Module and a terminal server is lost. The SIP Application Module uses the SMDI protocol to communicate information between itself and a voicemail server. If the connection goes down,

•Message Waiting Indication notification to subscribers stops.

•Calls routed to the voicemail server are not sent to the appropriate mailbox.

However, depending upon the voicemail server’s capabilities, the calls may be answered by a default mailbox and the originator can enter the desired mailbox number in which to leave a message. In the same way, users may be able to retrieve their voicemails (for example, they get routed to the default mailbox and are prompted to enter their mailbox). Again, this functionality depends upon the voicemail server being used.

The SIP Application Module repeatedly tries to re-establish the telnet session to the terminal server. If the alarm does not go away in a few minutes, then the terminal server needs to be checked and possibly re-booted. Also, administrators should check the voicemail server to make sure it is running correctly. If problems persist, contact your next level of support.
