[Asterisk-Users] Diva Server BRI echo options

[Giuseppe]

Hi!
I'm always getting this error when echo cancellation should start.

  == ISDN3: Setting up echo canceller (PLCI=0x203, function=1, 
options=4, tail=64)
  == ISDN3: Setting up DTMF detector (PLCI=0x203, flag=1)
    -- ISDN3: Error setting up echo canceller (PLCI=0x203)
Apr  3 10:49:30 WARNING[17266]: chan_capi.c:3334 show_capi_conf_error: 
ISDN3: conf_error 0x300b PLCI=0x203 Command=FACILITY_CONF,0x8497
       > CAPI INFO 0x300b: Facility not supported

I've googled a lot looking for this, and the only things I found was 
some logs like this:

   -- Setting up echo canceller (PLCI=0x101, function=1, options=2, tail=64)
    -- Echo canceller successfully set up (PLCI=0x101)

The unique difference is the parameter: "OPTIONS=2"
Maybe OPTIONS=4 is not supported by my card? (card: eicon diva server 4/bri)
Where this parameter can be set?

Thanks for your time!

Giuseppe
