Hello, I purchased several devices at the sale: - SIPURA SPA-2100 MAC: 000E08ECF162 S/N: 88012GA65696 - SIPURA SPA-3000 MAC: 000E08CAEE76 S/N: 88012DA04269 Both devices are serviceable. Unfortunately, the previous owner has set a password that does not allow me to configure. When I try to use the web interface to access the device, I have an authorization request: https://www.dropbox.com/s/ nttpk5ia32g9mj6/ sipuraAuthIssue.png?dl=0 Standard passwords user/user, admin/admin do not match. I have same problem when I use voice menu of device. I tried 73738# it asks for a password. The devices do not have a reset button, which would allow me to return to the factory settings. In the user guide, I also did not find information on how to solve this issue. I will be grateful for any recommendations that will solve my issue. Thanks, Oleg ... View more
