Generally you should get support for hardare cards from your vendor. This is true even when the vendor sponsors this forum.

However, I don’t think you want to put the second group into a from_pstn context, but rather to put them into a context that rejects calls.

The way you do that is to have two channels lines, and to change the options between the two.

You would use group to select for the outbound only channels, not context.
