Inter-Tel 5000 IP Resource Usage
On the Inter-Tel 5000 platform, IP resources are used to provide the following call processing
capabilities:
• IP endpoints
• IP network connections
• Faxing between Inter-Tel 5000 nodes
The correct allocation of IP resources is an important factor in maintaining a system that func-
tions without calls being blocked. Field technicians can promote nonblocking system perfor-
mance by making sure that the allocation of system IP resources is appropriate for the
customer’s needs. System administrators having questions or concerns about the allocation of
system IP resources should contact their Inter-Tel equipment and service provider.
Network Capability
Two or more Inter-Tel advanced communication platforms, Inter-Tel 5000 and/or Inter-Tel
Axxess, can be connected with T1/E1/PRI network spans to form a network. To the user, the
network appears as one integrated system. With few exceptions, the user can perform all of the
functions across the network that can be performed within a single system or node.
In an Inter-Tel private network environment, IP endpoints can be programmed to traverse, or
negotiate, Network Address Translation (NAT) tables, which may be used as a firewall. The
Inter-Tel 5000 may be placed inside a NATed firewall by utilizing a static NAT assignment that
allows IP endpoints to operate inside or outside the NAT/firewall. For more information about
programming IP endpoints to traverse a NAT/firewall, contact your Inter-Tel service provider.
The Inter-Tel CS-5200, CS-5400, or CS-5600 can operate as a stand-alone system or as a node
in a network of up to 99
1
Inter-Tel 5000 or Inter-Tel Axxess nodes. For network connectivity,
Inter-Tel Axxess Converged Communications Platforms require software v7.0 or later for T1
point-to-point protocol (PPP) networking. IP networking requires v8.231 or later system soft-
ware, IP Resources Card (IPRC) firmware v9.0.0 or later, and applicable licensing.
1. The 99 node capacity requires Inter-Tel 5000 version 2.1 or Axxess version 10.0.
