IP Line Description, Installation and Maintenance
When configuring the allocation of shared versus private resources,
consideration must be given to the number of private resources that are
needed. Enough DSP resources should be configured to prevent the IP Phones
configured in Shared Zones from running out of channels.

Run-time configuration changes

IP Line 4.5 enables most changes to be made without disabling or rebooting
the Voice Gateway Media Cards. After adding configuration information for
a new Voice Gateway Media Card and downloading the BOOTP file to the
Leader, a new Voice Gateway Media Card can be added to an existing node
without rebooting the other cards.
The following exceptions require a reboot:
• a role change; that is, changing a Leader to Follower or changing
Follower to Leader.
• changing the node IP subnet masks or gateway IP addresses requires a
reboot of all cards in the node.
• changing the AudioPort parameter in the “config.ini” file on the Voice
Gateway Media Card requires a reboot of the card
• changing the IP address of a particular card so it can retrieve its new IP
address information.
WARNING
The Call Server does not search for voice gateway
channels in Private Zones when the IP Phone is
configured in a Shared Zone. Only IP Phones configured
in the same Private Zone can use the Private Zone voice
gateway channels.
Since the voice gateway channels in the Private Zone
are not accessible to IP Phones in the Shared Zone,
ensure that only enough private channels are configured
to cover the IP Phones in the Private Zone. Do not
configure more channels than are required in the Private
Zone as the Shared Zone IP Phones cannot access
these channels.
