1. Introduction The sample configuration, depicted in Figure 1
illustrates an Avaya IP406 Office Server and Cisco Call Manager
operating in different subnets and Virtual LANs (VLANs) connected
by an 802.1Q trunk. IP406 Server is configured with extensions
within the range 10000 to 19999, while Cisco Call Manager is
configured with extensions within the 20000 to 29999 range. All IP
endpoints are provisioned statically.

3. Configure the Avaya™ IP Office Server The steps that follow
assume that the IP Office Management program is installed and
running on a PC that is networked to the IP406 Server. The IP406
Server has been “opened” from the Manager program and the system
password has been entered. Before any changes made in the Manager
Program take effect, they must be communicated to the IP406 Office
Server by selecting Save from the File menu item.
Step 1 From the Manager Configuration Tree, select System and
then the LAN1 tab to view the IP Office IP address. This is the
address that will be used in the Call Manager Gateway Configuration
of Section 4.4. As shown in Figure 2, disable the IP Office DHCP
server.
Figure 2: IP Office System-LAN1 tab
Select the Gatekeeper tab. Check to ensure that Auto-create Extn
Enable is checked. Auto-create Extn allows the IP406 Server to
automatically provision an IP Phone when it registers to the IP406
Server. This capability will be used in Step 8.

Step 2 From the IP406 Server Configuration tree, select Line and
then, from the right hand pane, right-click the mouse to select New
to create the VPN line (H.323 trunk) that will be used for calls to
and from the Cisco Call Manger as shown in Figure 3.
• Assign a unique Line number and Incoming Group ID and Outgoing
Group ID. • The number of channels should be adjusted to meet
intersystem communication needs
within the capacity of the network.

FastEthernet port 5/1 is the trunk to the P333T-PWR (VLAN 200).
As a trunk, the packets passed are tagged with the VLAN identifier
and a priority marking. FastEthernet 5/9 is the Call Manager port.
The port is assigned to the “call manager VLAN” (VLAN 50).
FastEthernet 5/10 is for the Cisco IP phone. In-line power is
supplied by default. The port and phone are configured for tagged
packets and for the “voice” VLAN as 50. VLAN 50 is established as
the Call Manager VLAN with an interface to the router at
192.16.50.71 VLAN 200 is the IP Office VLAN with an interface to
the router at 192.16.200.71

level to 7, the highest level. Set the port to be a member of the
IP Office VLAN (VLAN 200). Set the port to be enabled. Set the
Management PC port to be a member of VLAN 200. Set the Cisco 4224
802.1Q trunk port to use VLAN tagging via the 802.1Q protocol. Set
the port to be a member of VLAN 200. Set the IP Office 406 Server
port to the highest priority level (7). Assign the port to VLAN
200.

7. Verification Steps • As always, perform basic network level
verification (e.g., pings). • Run the IP Office System Monitor with
Settings-->H.323 set as shown in Figure 20 to monitor the H.323
exchanges with Cisco.
Figure 20: H323 Monitor Options
• Use Cisco Call Manager “Trace” (Application-->Call Manager
Serviceability) capabilities to create files similar to IP Office
System Monitor files to follow call progress.
8. Conclusion By following the steps of these Application Notes,
the reader will have successfully integrated an Avaya IP406 Office
Server and Cisco Call Manager. These Application Notes can also be
used as a basis to create more complex configurations, including
those with WAN networks and dynamic IP address plans.
