    Hello, I have been following your posting regarding several twilio projects. I am looking to to SIP to PRI with twilio elastic trunks and a adtran Netvanta 6240. Did the above end up being a viable solution?

    Yes, I have Adtran 908 2nd gen and NV6310 Twilio SIP to PRI in production.

    Wow great to know! Was the configuration tweaked from this one? How did you resolve the issue of the multiple incoming sip requests from all the twilio domains?

    This is set up with the E. 164 dialing? My endgoal is to integrate to a Panasonic TDE PRI interface.

    Sorry, I don't understand "multiple incoming sip requests" Twilio send SIP traffic to the Session Border Controller IP directly.

    This one for E.164 dialing.

Extracting and using a modified VMWare Player BIOS or UEFI firmware

https://pete.akeo.ie/2011/06/extracting-and-using-modified-vmware.html Extracting and using a modified VMWare Player BIOS or UEFI firmware (updated 2016.05.17 for VMWare UEFI firmware extraction) One day or another, you may want to play with BIOS/UEFI firmware modification. But before jumping into physical motherboard flash alteration, where the consequences of a mishap can be difficult to salvage, experimenting with the BIOS/UEFI in a virtual environment sounds like a sound first step. You have of course the opportunity to do so using  bochs , however the ubiquitous nature and ease of use of the (freely available)  VMware Player  can turn the latter in a much better candidate for the job if you don't really care about the extra features that bochs brings in. This post details how one can extract the BIOS/UEFI firmwares used by the VMWare Player, and how to setup the player to use a modified one. Download and install VMware Player. The current version of VMwar...

Windows 11 internet/account bypass

https://github.com/the-P1neapple/WinJS-Microsoft-Account-Bypass WinJS-Microsoft-Account-Bypass Overview This guide explains a method to bypass the Microsoft Account (MSA) requirement during the Windows 11 Out-Of-Box Experience (OOBE) by using the Developer Console to invoke a hidden local account setup screen. This method was discovered by examining the Windows 11 OOBE source code, which revealed an event listener for a hidden  _localAccountButton . Note A faster method has since been discovered using Command Prompt ( Source ), this repo was made 7 months prior to that discovery. The method I have documented is still the only known method for S-Mode installations. Following these steps, you can create a local account without needing to sign in with or create a Microsoft account. I also have a  Youtube Tutorial  that follows the same instructions below Steps to Bypass Microsoft Account Setup 1. Start Windows 11 Setup Begin the Windows 11 Setup Process. Select your region a...
