Hello list!

Im having trouble receiving PRACK over a PROXY.
For some reason the stack drops the PRACK when coming from the proxy with
the following TRACE message:
 4432 DEBUG [PipelineThread-1] ua-b -
gov.nist.javax.sip.DialogFilter.processRequest(DialogFilter.java:329)
[Processing PRACK for dialog gov.nist.javax.sip.stack.SIPDialog@6545d2]
 4432 DEBUG [PipelineThread-1] ua-b -
gov.nist.javax.sip.stack.SIPDialog.handlePrack(SIPDialog.java:2432)
[Dropping Prack -- ReliableResponse not found]
 4438 DEBUG [PipelineThread-1] ua-b -
gov.nist.javax.sip.DialogFilter.processRequest(DialogFilter.java:364)
[Dropping out of sequence PRACK ]
 4439 DEBUG [PipelineThread-1] ua-b -
gov.nist.javax.sip.stack.SIPTransactionStack.removeTransaction(
SIPTransactionStack.java:1178) [Removing Transaction =
z9hg4bk452d4334-2b94-4fbf-9b0e-b2a9cec755af transaction =
gov.nist.javax.sip.stack.SIPServerTransaction@a8fe2982]

Below you'll find the 183 response which Im using to create the PRACK as
well as the incoming PRACK.
Both clients are based on Jain-SIP 1.2.

Any ideeas?
thanks/j =)
