In regards to the blog post:

If you use the following rule instead of what is mentioned in the article each model phone can get its own firmware.
<Upgrade_Rule group="Provisioning/Firmware_Upgrade">http://%%pbx_ip%%:%%pbx_http_port%%/provisioning/$PN.bin</Upgrade_Rule>
The $PN will be replaced with SPA5XXg by the phone. For example on the 504g you just need to copy the last firmware to spa504g.bin and place it in the provisioning folder.
Hope this helps!
