2 digum cards

Dears,

I have a digum card (Wildcard TDM800P Board 2) working good
recently i added a 2nd card (Wildcard AEX800 Board 1)
and did a pstn setup for both
the 2nd card is installed
trixbox can see 16 channels
but it is not working

it drops calls and don't deliver them

any idea

my channel info is:
