[Serusers] PRACK

   Hello,

I have a problem with tow Cisco ATA 186 both having
version v3.2. When I try to make a call on my side I
hear that the phone is ringing 3 times and then the
call is disconnected. On the other side, the telephone
is ringing  10 times. I belive that the problem is
when one Cisco sends a PRACK packet and and it receive
"420 Bad request" from de sip server. Then the call is
disconnected with error "504 Gateway Time-out". Below
I put the logs from the tow ATAs. Any help in solving
this problem will be appreciated.

  Thanks.


Call from: 3327xxxx to 33271yyyy (log from the calling
ATA):
