6. Your problem:
i m using x lite as my softphone which is works fine with brekeke sip server when i connect
through LAN at both side.
but when i connect one of the client from wifi the registration is successful but not
able make a call.
it register with private ip of wifi network with sip server.
which kind of settings and dial plan need to resolve this problem?

Is there any firewall or router between the SIP Server and SIP client on the Wifi?
What kind of SIP response did you receive from the SIP Server when you made a call from the client?

No there is no firewll between the SIP Server and SIP client on the Wifi. I am able to make call between two clients.but after receiving call voice I am not able to hear a voice.I got the session established response from Sip server.

When I try to connect from Wifi with firewall I face same problem.

Are you using X-Lite in the Wifi side also?

Try RTP-relay at the Brekeke SIP Server.
