I havent had much auto provisioning experience, however, what about just using IPTables to create an access list essentially for known IPs to connect via HTTP/HTTPS and block all other addresses. This would only work if the phones are coming from a Static IP, but I figured i'd give my 2 cents to try and help. <br>

<br>
has anyone experience with auto provisioning IP-phones on different
locations through a central public provisioning server ? You use http
or https ?<br>
<br>
Is there a danger that one uses a different MAC-address in the
provisioning link to obtain SIP username / password settings ?<br>
<br>
<br>
Kind regards,<br>
