How do I deploy IP phones in batches using DHCP?

Q: How do I deploy IP phones in batches using DHCP?

A: After being connected to the DHCP server and powered on, the IP phone sends a request to the DHCP server for an IP address. In response, the DHCP server returns an IP address, together with the URL of the UPF file (containing the addresses of the configuration file and the file server) carried in the Option 246 parameter. The IP phone then obtains the configuration file, version file, signal tone file and certificate file of the target version for the specific phone model from the file server to update its configuration.

Prerequisites

You have prepared the following items:

l  HTTP file server

l  DHCP server.

l  Version file, configuration file (Config-eSpace7910/Config-eSpace7950/Config-eSpace8950.xml), signal tone file and certificate file of the target version for the specific phone model.

l  (Optional) DNS server

To use domain names in file URLs, prepare a DNS server.

Procedure

   Step 1          Modify the configuration file.

In the configuration file, set related parameters (see Table 2-1 for detailed parameter descriptions) based on the actual network environment. For details about the other parameters, see the eSpace 7910 and 7950 IP Phone Configuration File Parameter Description and eSpace 8950 IP Phone Configuration File Parameter Description.

Table 1-1 Parameter description

If you only need to deliver part of the configurations in the configuration file, add the MFlag="1" field to the configuration items to deliver.

Assuming that the original fields in the configuration file are as follows:

<Lang language="zh-CN"/> 
<CallOut enableCallout="0"/>

If you want to change language to en-US and no longer deliver the CallOut configuration, change the configuration file as follows:

<Lang MFlag="1" language="en-US"/> 
 <CallOut enableCallout="0"/>

After the change, only the lang configuration is delivered and the language is changed to English.

   Step 2          Place the files to upgrade into the file server's default directory, for example, C:\Program Files\Apache Software Foundation\Apache2.2\htdocs. The files include the version file, configuration file, signal tone, and certificate files and manufacturer specified configuration file.

   Step 3          Prepare a UPF file. For details, see the eSpace 7910 and 7950 IP Phone Administrator Guide and eSpace 8950 IP Phone Administrator Guide.

   Step 4          Set the Option 246 parameter of the DHCP server (configured on the Windows Server 2008) to the UPF file URL.

l   The URL specified by the Option 246 parameter prevails, even when different URLs are set in other parameters.

l   The URL for the UPF file must contain the name of the UPF file and must not contain spaces or Chinese characters.

Table 2-2 lists different settings of the Option 246 parameter.

Table 1-2 Option 246 parameter settings

   Step 5          Power on all the IP phones to be deployed.

All the IP phones automatically obtain their IP addresses and download desired UPF files. According to the upgrade file directory specified in the UPF file, the IP phones upgrade their versions and download configuration files for batch configuration.
