I have one more question how can i change the port of a client or a server .Since the server having default port 5061 & client having 5060. I believe it could be because of that also .Plz let me know if u know the answer

no, RTP port is dynamic. 5060 is for sip. it looks that 1000 and 2000 and also your asterisk are in the same network. and it is working. please change some other terminal to test again.

ya they are in the same network , i tried in other system also but the same problem is occuring no voice is transferring. I believe it could be iptables problem ,firewall problem .
Any ideas
