Do you need to proxy calls to asterisk? If that is the case, you need to make sure that the NAT flag is set. g-) Arun Kumar wrote: Hi, I've configured my SER to send calls to my Asterisk server when user connects to ser and dial a number ser forwards this to my Asterisk server and my asterisk server ask for my pin number saying "Please enter your pin number". In this config I'm using rewritehostport(ip:port) to forward the calls and its working fine. But, Now I've implemented the LCR when I see ngrep calls are going to my asterisk server but I'm not able to hear any sound from my asterisk server saying "enter your pin number". Please help in this issue.
