Asterisk Box has two IP Addresses (Public & 192.168.3.1 (Private as server))
client is directly connected to asterisk at 192.168.3.2 and try to dial out ....

Now 

caller can hear the person he just called...but the dialed person cannot hear the
caller...

One more very important thing that I should mention here.....
Both hears each other just for 2 seconds.....then voice goes to Half Duplex or One way...

    -- SIP/yuppyline2-082a is ringing
    -- SIP/yuppyline2-082a answered SIP/270809-e3f5
    -- Attempting native bridge of SIP/270809-e3f5 and SIP/yuppyline2-082a
  == Spawn extension (TestOut, 12105799821, 5) exited non-zero on 'SIP/270809-e3f5'


everything works fine (only for 2 or 3 seconds) before the line "   -- Attempting native bridge of SIP/270809-e3f5 and SIP/yuppyline2-082a" <-----  as soon as this line comes up in the CLI .... I get the one way voice.....

anyhelp please???
