AAH configuration with Sipura 3000

Here is what I got: AAH 2.0, Sipura 3000, ATA-186 and X-ten configured,
I can make calls from any ext. based on Sipura, Cisco or X-ten
I can dial out on Sipura FXO fine, But AAH does not ansfer calls on the this FXO port?! Sip debug shows no events from Sipura.
Any ideas what is going on?
