  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?
