How to Unlock a Linksys SPA2102 ATA VoIP Adapter

Did you just buy a VoIP SIP Adapter on eBay only to find out it was locked by the old VoIP provider?  Bummer.. We’ll don’t despair, follow the instructions below and the helpful Video to find out how to unlock a Linksys SPA2102 ATA Adapter.


These instructions came from an old Post I found buried on the Web Archive Boards.  The original post was on a blog that is no longer resolving.

The original instructions were for unlocking a Sunrocket Gizmo SPA2102-R and were taken from SRGizmos which is not defunct but that link will take you to the web archives page where it remains. You can also visit the gizmo password blogspot. However the instructions in the video work. These should work on for any Cisco SPA2100 or SPA2102 ATA Phone Adapter.

A set of instructions was also found on  This is a Blogspot link and has been updated.  However the original post mentioned that all the suggested passwords failed due to reprovisioning.
