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):
