Long story short, changing the MAC address had no effect whatsoever.<\/p>\n<p>I did, however, discover that the VTAs apparently run an embedded flavor of Linux (cool!) with an SSH daemon installed and running by default (cooler!). Unfortunately, it uses a different account than the web interface (bummer). A glimmer of hope was the <a href=\"http:\/\/www.bargainshare.com\/index.php?showtopic=87504\">instructions for unlocking<\/a> various SIP devices, include the D-Link VTAs. But I was shutdown yet again: the manufacturers have apparently gotten smarter and started patching up the security holes that people have been hacking into.<\/p>\n<p>Now it&#8217;s down to the wire. Wireshark, that is. I used Microsoft&#8217;s bundled <a href=\"http:\/\/en.wikipedia.org\/wiki\/Internet_Connection_Sharing\">ICS<\/a> to become a gateway on my wired NIC, which is attached to the VTA via a cross-over cable. Then I started sniffing traffic. It looks like the VTA now has DNS server addresses hard-coded into the firmware, removing the easy way to rewrite DNS requests. ARP spoofing? But it&#8217;s definitely making a request for an XML provisioning file, which I was also able to download. Unfortunately, it&#8217;s encrypted.<\/p>\n<p>Maybe this is more trouble than it&#8217;s worth.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>After discovering that, if left up to Vonage, the D-Link VTA-VD device I just purchased off eBay would be useless, I became determined to get it working.
