Installing the VoIP Indoor Intercom

Configure the Autoprovisioning Parameters

• After rebooting, the board will configure itself according to this new file.

Autoprovisioned

Firmware Upgrades

An Autoprovisioned firmware upgrade only happens after a reboot, will take roughly three minutes,

and the web page will be unresponsive during this time.

The 'FirmwareVersion' value in the xml file mu

st match the version stored in the 'FirmwareFile'.

<FirmwareFile>1013-intercom-uImage</FirmwareFile>

If these values are mismatched, the board can get stuck in a loop where it goes through the following

sequence of actions:

1. The board downloads and writes a new firmware file.

2. After the next reboot, the board recognizes that the firmware version does not match.

3. The board downloads and writes the firmware file again.

CyberData has timed a firmware upgrade at 140 seconds. Therefore, if you suspect the board is

stuck in a loop

, either remove or comment out the FirmwareVersion line in the XML file and let the

board boot as it normally does.

Autoprovisioned

Audio Files

Audio files are stored in non-volatile memory and an autoprovisioned audio file will only have to be

downloaded once for each device. Loading many audio files to the device from the web page could

cause it to appear unresponsive. If this happens, wait until the transfer is complete and then refresh

the page.

The device uses the file name to determine when to download a new audio file. This means that if

you used autoprov

isioning to upload a file and then changed the contents of this file at the TFTP

server, the device will not recognize that the file has changed (because the file name is the same).

Since audio files are stored in non-volatile memory, if autoprovisioning is disabled after they have

been loa

ded to the board, the audio file settings will not change. You can force a change to the audio

files on the board by clicking Restore Default on the Audio Configuration page or by changing the

autoprovisioning file with “default” set as the file name.
