IP Office deployment scenarios

When preparing IP Office for D100 deployment, you must configure the correct type of network addressing. The location of the DHCP server and the number of IP Office servers in the subnet determine the network addressing scenario.

By default, the base station is configured as a DHCP client and IP Office is the preferred DHCP server. In this scenario, the system requires minimum configuration. The base station obtains the IP address, subnet mask, default gateway, and configuration server address from the DHCP server.

If the network uses a third-party DHCP server, the base station obtains the IP address, subnet mask, and default gateway from the DHCP server and then runs an IP Office discovery mechanism to obtain the configuration server address. The base station then registers to the first IP Office that responds. In this situation, only one IP Office server can be available on the subnet. Refer to Scenario 1.

If multiple IP Office servers are available on the subnet, the IP Office discovery mechanism will not work properly. You must use static addressing where multiple IP Office servers exist on the same subnet. Refer to Scenario 2.

When adding a new SIP DECT Line, IP Office Manager assumes that the base station acts as the DHCP client. In some deployments, configuring the base station's IP parameters statically might be desirable.

A single IP Office can support up to four base stations. If multiple base stations are connected to an IP Office, you must configure the MAC Address parameter for each of the SIP DECT Lines using IP Office Manager. If only one base station is connected to the IP Office, you do not need to configure the MAC Address.

Consider the following network configuration scenarios before you deploy the D100 terminal.
Network configuration Scenario reference
A single IP Office in the subnet that hosts the DHCP server. Follow Scenario 1
A single IP Office in the subnet with DHCP hosted by a third-party server. Follow Scenario 1
Multiple IP Office units with the DHCP located on an IP Office unit where the base station is configured. Follow Scenario 1
All other network configuration scenarios require static IP addressing. Follow Scenario 2

Scenario 1

You must configure the base station in IP Office Manager.

In this scenario, you can still configure the base station with static IP parameters. If you configure static IP parameters, the base station uses and maintains these parameters after rebooting the base station, or until you modify the IP parameters in IP Office Manager.

Procedure

  1. Configure the base station in IP Office Manager:

    Double-check the values you enter as you might inadvertently lose connectivity to the base station by providing incorrect values.

  2. Connect the base station to the subnet where the IP Office can be reached.

    The base station downloads the configuration parameters and reboots if any parameters were modified.

Scenario 2

You must use static IP addressing for the base station.

In static addressing, you must configure each base station individually in IP Office Manager with network-specific addressing. In addition, you must configure static IP addressing on the base station prior to installing it on the network.

Since static addressing requires DHCP to be off, the base station cannot retrieve the network parameters from IP Office and you must turn off the DHCP client and configure the base station's network parameters using the Base Station Web Management Interface.

A base station is configured as a DHCP client by default, so you must access that base station and configure the addressing parameters, otherwise the base station assigns an address automatically. When there is no DHCP server in the subnet, the base station uses the following addressing parameters:
  • IP Address: 192.168.1.100

  • Mask: 255.255.0.0

Once you know the IP address of the base station, enter this address in a web browser on a PC connected to the subnet. Doing so provides access to the Base Station Web Management Interface. For more information, see Base Station Web Management Interface .

Procedure

  1. Configure the base station in IP Office Manager according to the instructions in Configuring the D100 using.
  2. In the Base Station Web Management Interface, configure the static IP parameters for the base station. See Configuring the D100 using the Base Station Web Management Interface.

  3. Connect the base station to the subnet where the IP Office resides.

    The base station downloads the configuration parameters and reboots if any parameters were modified.
