[asterisk-r2] Dahdi hangup on OpenR2

[Jorge Jacques]

Hi all, 

I'm getting this errors in my asterisk log and my calls are hanging up

dahdi_hangup: disconnecting MFC/R2 call on chan X
dahdi_ast_cause_to_r2_cause: ast cause 16 resulted in openr2 cause 6/Normal Clearing
chan_dahdi.c:8215 handle_alarms: Detected alarm on channel X: Yellow Alarm
handle_clear_alarms: Alarm cleared on channel X

I already re-check my config and replace the balun but it does not work.

Here is full logs:

This is my config:
