I just can tell you that it is able to handle all this situation. But I can't help you if you just say "A cant call B". You find to dig into the problem. Learn how SIP works. Learn how to use ethereal and ngrep to watch the SIP call flow. Use ethereal to watch the RTP streams. Use xlog to watch how SIP messages yre routed by your SIP proxy.
Then post the excat problem and also post the correspondig SIP call flow (e.g. use ngrep -W byline)

Thanks! I have tried nat-mediaproxy.5.0.cfg and gw-pstn.5.0.cfg with modification. However, none of them can work completely.
For nat-mediaproxy, I have mediaproxy1.4.2 installed and then follow the document to adjust the parameter of the configuration file. Then there are 2 IP phones (A & B) connect (NAT) to the SIP server. The result is A can contact B but B failed to contact A.
For gw-pstn, the case is more worst. A & B is the internal IP phone. C is PSTN phone. None of them can make a call to any other.
Just want to know anyone can make both configuration work. Any tricky action that needed to take care. Please advise.

note: do not try to use mediaproxy before you solved REGISTER handling
