[cisco-voip] PRACK and Cisco ATA 186 v3.2

[Dana Turcanu]

 Hello,

  I there any problem with PRACK method in v3.2 of
Cisco ATA 186? I get "400 Bad Request" from the server
when the Cisco tries to use that method:

   Another phone using PRACK method is working fain,
so I don't belive that the problem is at the server
side.

 Any help will be appreciated.

Thanks.
