Dialogic and Asterisk Integration

Hi All,

I have an outbound application which work on Dialogic 300JCT, Now what i am trying linking the dialogic and digum TE110P using a E1 cross over cable and trying to make call from dialogic to Digium.

The problem is even while the both the boards is sync (glowing green) am i unable to make calls.

Configured ISDN in both the boards.

Please throw some light
