   I logged the call from the tow Cisco ATA 186. The
calling ata is sending PRACK and the answer is comming
from the server:

In the log from the called ATA there is no PRACK or
400 error.
  Can you tell me what do I have to change in ser
configuration in order to allow routing of PRACKs?

 Thanks.
