Downloading VoIP Firmware

If you have installed an AT-AR027 VoIP PIC, you now need to download and install the VoIP firmware onto your PIC. Before you begin, check that the PIC Error LED on the PIC is off, and that the PIC has been recognised by your switch or router, using the show system command.

1.Download the VoIP PIC firmware.

Point your web browser at www.alliedtelesis.com/support/software/. Navigate to the PIC product information page and find the firmware files you need from the support page. You will need:

•the PIC boot code, which is responsible for loading the protocol image onto the PIC

•the images for the protocols you wish to run on the PIC—SIP and/or H.323 Download the firmware files you need and save them to your TFTP server.

2.Load the boot code onto your switch or router.

To load the boot code from your TFTP server, use the command:

load method=tftp destination=flash server={hostnameipadd}

file=filename

3.If possible, load the protocol image onto your switch or router.

If you have enough space, load the protocol image onto your switch or router’s flash, so that it does not need to be continually connected to an external TFTP server. Use the load command as described above.

4.Set the boot code and protocol image.

To set the boot code on the switch or router, use the command: set voip bootcode=filename server={ipaddflash}

This command sets the boot code filename, and specifies the location of the protocol image that the boot code will load.

To set the name of the protocol image (file), and specify what type of VoIP protocol the protocol image supports, use the command:

set voip file=filename protocol={h323sip} type={fxsfxo}

5.Set the interface for the VoIP traffic.

To set the preferred interface for VoIP traffic, use the command: set voip public interface=interface

If a logical interface is not specified, 0 is assumed (that is, eth0 is equivalent to eth0-0).
