10-34
When the attendant's telephone exists on a secondary system, alarm

information cannot be displayed on the attendant's telephone.
Only the voice mail connected with the Primary System can be used. Since the

recording data of the voice mail is not synchronized, the content originally
recorded by the Primary cannot be succeeded, though the voice mail of the
Secondary System can be used after it becomes the Primary after Fail-Over.
Synchronous Ring and NetLink cannot be used together.

The system IP address set can be connected as Primary by turning on Program

51-01-03 instead of Program 51-03-01 and specifying the IP address of the
Primary using Program 51-04-01.
During Fail-Over, the IP Multiline terminals can connect to the Secondary

System, however when the Primary System comes back online, a 60-second
reset of the Secondary System is required. IP Terminal Programming is
required.
Only the voice mail connected to the Primary System can be used. During Fail-

Over if a InMail Flash is installed in the new Primary it will now function. This is
done automatically, and no programming is required. During the Fail-Over the
messages do not synchronize to the new InMail Flash. After Recovery the
Original InMail Flash will now function, and any messages stored on the other
Inmail flash will not synchronize.
