To all RTP300/WRTP54G owners, Here is how to can completely access (unlocking) your units: Read all posts right below this post (and on for its discussions), particularly where the mention of RC4 (link to rc4.c file) posted by czyc. If you read those posts, you will notice there's a link where you can download a copy of rc4.c file (Sorry, I don't want to risk myself to provide the link here). The reason is simply this particular rc4.c file was once released on to some of the cyberphunks boards by some crackers. Accordingly, it was a reverse-engineered code based on the RSA encryption code which is protected by the US gov. Be sure to download this rc4.c file. On a Linux machine, you can just type this cc -o rc4 rc4.c to compile the rc4.c file into a binary program. Anyway, once you obtained the code, here is what you need to do: Factory reset your RTP300/WRTP54G unit. Remember, you will need to perform a factory reset on the Router + Voice which may take more or less of 40 seconds to hold the pin reset button. If you just press the reset button for less than 30 seconds, you will only perform a factory reset on the router and all the provisioned information on your RTP300/WRTP54G by Vonage are still there. Use this trick to access the Voice_adminPage to retrieve all the information you will need, i.e. the encryption key, the TFTP/HTTP servers, firmware name, and the directory to obtain the XML file. On a Linux (you will have to port this to other OS platform other than Linux) machine, just compile the rc4.c file, i.e. cc -o rc4 rc4.c, and use it to decrypt the XML file, i.e. rc4c "key" < ti1234567890.xml > ti1234567890.xml.txt, where ti1234567890.xml.txt is your decrypted XML file. Once decrypted, you can see the Admin password, make the necessary changes to the Admin password, provision rules, re-encrypt the XML file, and have your unit provisioned with the newly re-encrypted XML file. This way, you can freely access your units; however, clicking the Voice menu will still lead you to the nasty message. To access the Voice page, your will point your browser to this Voice_adminPage page, instead. (NOTE: This was added later on). Please notice here: I provided the above mentioned information only for the shake of education here. If you render your device to useless and/or Vonage (or your VoSP) has terminated your accounts and starts charging you for some fees because you have modified your RTP300/WRTP54G based on the above information, you are responsible to what you have done. You have been warned! Good luck to you all.
