Thank Your very much Steven, for good advice! I updated yesterday and everything works fine now.
It is true, SPA301 work correct with version 8.1.0, and not with 8.0.0! I don't see this writen anywhere.
Another problem I see with old version - the voice trunk groups are not working correctly with BRI ports!
If you have to have different trunk group for every port - at the moment of getting out to operator, they are selected randomly, and you get message "unknown number", because trying to select another line (not connected).
Congratulations for the Team and Members of this community - this content and work , that are published here, is very useful !
