You should read the chapter in the cook book over NAT, Anthony did a fine job writing it… with that said I assume based on the description, the packet and your text the issue can be solved like this:

1. Set local-network-acl (rfc1918.auto willy usually be fine.'
2. set ext-sip-ip and ext-rtp-ip to ‘autonat:x.x.x.x’,
3. Restart your sofia profile or FreeSWITCH
4. Make sure your firewall forwarding rules are setup properly.

It should just work unless your firewall/nat/router has an ALG in it.

prefixing the ext-*-ip bits with autonat: toggles a flag to make sofia dynamically figure out if it should use the private or public address in the sip packet using the local-network-acl to make that decision.

But when I made a call outside from the LAN from within the LAN, then the call is working for only 30 seconds as well. And If I tried to call from outside the network into the LAN then this time audio is not working anymore, this same issue with the call was made outside to outside from the network. I have enter the Public IP in the field of Ext-RTP-IP and Ext-SIP-IP.
