Figure 146. Message from inactive system
In MaxAdmin, dialog boxes that are invoked from the following locations are for board-
level configuration:
• Boards View
• Line Properties on the General tab of Extension Configuration
• Trunk Properties in the General tab of Trunk Configuration
Some board level configuration changes require rebooting the AltiServ system. For
example, changing a T1 board to PRI, or changing a VoIP board from 12 ports to 30 ports
requires rebooting the system. To change the board configuration of a gateway, you
must detach, configure, reboot, and reattach the gateway.
Limitations
The redundancy feature in MAXCS 6.7 has the following limitations:
• 3 or more NIC cards on a Softswitch are not supported.
• The Redundancy Administration dialog box can be invoked on the local system only.
Remote connection is not supported.
• The IP phone will have a new workgroup login time every time the system switches
over.
• The computer name of the Softswitch is not supported for external servers and
applications to connect with it. DNS name by dynamic registration is also not
supported.
• If clients connect with active system (either primary or secondary) through
redundancy IP address, the server will accept it, but it's not suggested.
• If a call includes a local resource channel or telephony channel (except SIP), the call
will be not kept after switchover.
• The board configuration (H.323, SIPSP, and HMCP if the system is installed as a
Softswitch with HMCP Media Server) for default gateway (gateway ID is 0) cannot
synchronize from the active system to the inactive system. So you must manually
configure the board both on the primary and secondary systems and make sure the
configuration is exactly the same on both systems.
• Diagnostic trace settings are not synchronized between the primary and secondary
servers.
