Sorry My Question was not very clear.
Asterisk System that is placed some where on local LAN (suppose in office
A) A sip(or any other whose softphone is available) phone Client that is
out side this local network (suppose at office B).

now if  I want the asterisk server to be avaiable for this sip phone.

As Asterisk Server is also behind NAT. SIP phone is also in any other
network.

How can I make them communicate. As in LAN i can easily by giving asterisk
server IP.

Don't put a SIP server behind destination NAT.  Just don't.

No,

Just moving the asterisk-server before the firewall won;t do any good.
because in that situation the firewall is in between asterisk and your
LOCAL sip-clients: you just solved one problem by introducing another
eg, the just moved the problem to another place

What you can do (perhaps not the best solution...) is having one
asterisk server behind your firewall, serving all your local
sip-clients. And another at the other side of the firewall, only for
serving remote clients. And have both systems talking to each other with
IAX instead of SIP

In that case you _only_ have to allow port 4569 for IAX instead of 5060
and 1...2 for SIP

  Asterisk System that is placed some where on local LAN (suppose in
  office A) A sip(or any other whose softphone is available) phone
  Client that is out side this local network (suppose at office B).
 
  now if  I want the asterisk server to be avaiable for this sip phone.
 
  As Asterisk Server is also behind NAT. SIP phone is also in any other
  network.
 
  How can I make them communicate. As in LAN i can easily by giving
  asterisk server IP.

  Depends on what your goals are.
 
What i have studied so far
I am confused with NAT issues. As i can have many SIP peers on
  local LAN it
works but from internet it donts. We need to do configuration at
  router
level and all things like that.

I also heard that in Pakistan VOIP is not allowed. We need to buy
  a liscense
that is very expensive and so on ...
 
  What exactly is your question?
