Private Networking
407
• Extension Numbers : When an extension number is changed or deleted, the network broadcasts
the extension change to the other nodes in the network, and the network updates all off-node
device lists appropriately. If the network is unable to export or import an extension because there
is an active programming session on that node, the node is unable to communicate with its Voice
Processing port, the node is down, or the links to the node are down, the new extension will not
be added to or changed on that node. You must manually change or delete the extension from
the node database.
• Extension Lists: Extension lists are limited to the phones or trunks on a single node.

Office 250 Features and Programming Guide
• Hunt Groups: UCD hunt group members can be off-node devices. ACD hunt group members
can also span nodes. Supervisors, however, cannot span nodes. All versions support supervi -
sors, recall destinations, announcement phones, and overflow phones on other nodes. the

• Phone Monitor: Because supervisors must reside on the same node as the hunt group, phone
monitoring can not occur across nodes. the

• Trunk Group s : the
MiVoice Office 250 Features and Programming Guide
• Trunk Lists: All trunks in a trunk group must reside on the same node as the trunk group.
• Outgoing Access: Because the network does not allow users to directly access trunks on
other nodes, each trunk group’s Outgoing Access must contain only phones on the local
node. Users must use ARS to access trunks on other nodes. Once an ARS call leaves the
originating node, the network ignores outgoing access restrictions.
• Ring-In Assignment: A trunk can ring in to a phone or Voice Processing application on
another node.
• Allowed-Answer Assignment: Phones cannot have allowed-answer assignment for trunk
groups on other nodes.
• Caller ID, DNIS, and ANI : The network retains trunk and outside party information and passes
that information along when a call is routed from node to node. the

• Call Routing Tables : Call routing tables can be used on a network. the
MiVoice Office 250
Features and Programming Guide
• You cannot route a call from one Call Routing Table to a Call Routing Table on another node.
When a Call Routing Table sends a call to another node, it cannot be routed to any additional
nodes.
• Trunks that ring in to call routing tables can only ring in to tables that are located on their
local node. They cannot ring in to a call routing table on another node.
• The network attempts to optimize routes so that calls do not route through a node more than
one time (looping). However, the network does not have the ability to dynamically reroute.
That is, if a node trunk group that was previously unavailable becomes available after the
network has already chosen another route, the network does not reroute using that node
trunk group.
• The network will try to optimize routes when calls have been transferred or reverse trans -
ferred across several nodes (possibly forming loops).
