[Users] audio problem in NAT helper..

[raviprakash sunkara]

Hi Users,
I'm cracking my head with audio problem..
I installed openser 1.0.1 in Linux  + freeRadius + RtpProxy + mysql

When I make a call ( which are behind the nat  ) the audio is not hearing
and audio signal of  Softphone is blinking up and down..
In  Debug output  I didn't see any
     SIP reply  or sip request  for ACK..
I thing so that, If  client nehind the NAT didn't receive the ACK. this may
be problem...

SIP/2.0 200 Ok
