Simple script that handles PUT and HEAD requests from Polycom phones, so you can finally disable your TFTP server.
This requires a new httpd configuration:
<Directory /tftpboot>
AddHandler php5-script .poly
AddType text/html .poly
RewriteEngine On
RewriteCond %{REQUEST_METHOD} =PUT [OR]
RewriteCond %{REQUEST_METHOD} =HEAD
RewriteRule ^(.*)$ put.poly?url=$1
</Directory>
