SIP SHOW PEERS showing Unreachable

Asterisk Asterisk SIP
1

I am able to get 200 OK from my SIP client [Written In Java. Based in JAIN SIP].
I am able to register the SIP client Successfully. But when I am checking sip show peers I am getting status=“UNREACHABLE”.
Below is my sip logs after getting 200 OK from Asterisk Server:

Is there is any of Reply I need to send from my code to make my code keep alive at Asterisk Server?

You need to comply with the SIP RFC, i.e. you need to reply. Any valid reply, including error statutes should work.
