Hello,
Hello,
Look at my ethereal file
In your file the PRACK reach the calling party and it respond with 200 OK.
In my case,the PRACK never reach the calling party and the server is returning 400 error.
Is this error returned because the request from tha Cisco ATA 186 is malformed??
Can some one give me a log of a call between tow Cisco ATA 186 ( version 3.2 - with PRACK method) passing through a SIP Proxy?

Are you sure the "400" comes from SER and not
from
the other endpoint? Do you allow routing of PRACKs in your
SER-Config?
I logged the call from the tow Cisco ATA 186.
The
calling ata is sending PRACK and the answer is comming from the server:

ser

PRACKs?
Thanks.
