I am trying to add the provider 12Voip as an identity on this phone. The green telephone symbol appears to be added correctly, there is a dial tone, but when I try to connect all I get is the error message "User not found". This Voip provider works correctly with another non Snom telephone. I have entered the data as requested here. I would be grateful for any help in identifying the issue as I assume I should have added something to another setting somewhere. Many thanks

Hi, the Snom 821 is unfortunately an End Of Support product I am afraid (it went in an end of life state back in 2017 as you can see here) and we are not currently able to offer support for this product.
