B400P in PMP L1 down L2 down

Hi guys,

We have a B400P on my asterisk box (mith misd 1.1.9 on elastix distribution 1.6.14), connected on port 1 with my provider, and on port 2 and 3 we have gsm gateways. The gateways are working correctly in PMP, L2 is down L1 is up, and when I a make a call the L2 goes UP. That's fine, the call is OK.

The problem is on port 1, If i make a call to this line, L1 goes UP and L2 too, but the call is drooped. I call again and in this case the call is OK. In a minutes, I can see:
P[ 1] MGMT: SSTATUS: L2_RELEASED
P[ 1] MGMT: SSTATUS: L1_DEACTIVATED

Other problem on port1 is that we have noise on the call.

Here is mi misdn.conf:
