Provisioning Linksys SPA-9XX and Cisco SPA-30X

First of all, a nice PDF with a bunch of useful links:

1. There are two ways of provisioning:

– using TFTP/FTP/HTTP server and pushing it’s address with the DHCP option, in case of using DHCP server in your network. In this case the phone will try to download the configuration/firmware from the server specified during the next reboot. But we need to reboot phones forcibly after that.

– without using DHCP server and dhcp-options. Just telling the phone with a direct HTTP request the URL path of config file/firmware to load, either from browser, or from Linux console, using curl. In this case the phone reboots automatically to apply the newly downloaded config/firmware (if there is an active call, the phone waits for its end and only then reboots to aply config. But I haven’t tried to upgrade firmware during the active call).

Download the archive with firmware, unpack it and rename the firmware file from something like spa50x-30x-7-4-9c.bin to spa.bin.

Next, we need some server, e.g. a small simple HTTP server weborf.
After installing, run it, specifying the directory with spa.bin file:

weborf -p 8000 -b /home/lexus/downloads/spa_303_firmware_7.5.5/

If there is Python installed on your machine, you may use its built-in http-server, running this command from a directory with spa.bin:

python -m SimpleHTTPServer 8000

Remember that it’s not always possible to skip firmware releases, for example I tried:
– 7.5.2 —> 7.6.1 – unsuccessful
– 7.5.2 —> 7.5.5 – OK
– 7.5.1 —> 7.5.5 – unsuccessful
– 7.4.9c —> 7.5.5 – unsuccessful
– 7.4.9c —> 7.5.1 – OK.

Read below how to upgrade the firmware.

2. Let’s imagine, we need to change the configuration of a phone. We need to disable the Call Forward feature.
First of all look through the XML-config file of a working phone: http://phone.ip/admin/spacfg.xml
To disable CallForward feature we need to change this parameter from ‘Yes’ to ‘No’:

Tip: all XML parameters are called the same way as in the web-interface, but with underscore instead of spaces

Create the spa303.cfg text file in your web-server directory:

And now tell the phone using curl to apply it:

curl --anyauth -u admin:pass http://phone/admin/resync?http://websrv.ip:8000/spa303.cfg

3. You may also provision phones from web-interface:


… but this is not true way :) .

It’s much more cool to do everything with curl:

curl --anyauth -u admin:pass
curl --anyauth -u admin:pass
curl --anyauth -u admin:pass

… they say, it’s also possible to use ‘–digest’ option in curl, but I haven’t tried, as ‘–anyauth’ works fine.

Tips and Hints:

Assuming you’re using ISC-DHCPD server:

        host spa303-1353 {      hardware ethernet 3c:ce:73:d3:f9:dc;
                                fixed-address; }

        host cisco303-1354 {    hardware ethernet 3c:ce:73:d3:e9:e4;
                                fixed-address; }

…and need to get all phone IP addresses from its config. Do:

grep -A1 spa dhcpd.conf | grep -vE '^#' | grep fixed-address | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'
grep -A1 cisco dhcpd.conf | grep -vE '^#' | grep fixed-address | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'

… and create a text file SPA_ips_from_dhcp.txt .

But DHCPd config may contain records of non-existent phones, that’s why we need to check if the IP addresses are real network devices (that they reply to OPTIONS SIP-requests), and these devices are Cisco and/or Linksys phones (useragent is Cisco… or Linksys…).

We’ll use sipvicious tool for that (make sure to have Python installed to run it):

python --inputtext=/home/lexus/SPA_ips_from_dhcp.txt | grep -i SPA | awk '{print $2}' | sed 's/.....$//'

… and write this list to SPA_ips_alive.txt .

Now it’s time to provision the actual list of IP-phones with the script:
