[asterisk-users] best practices for running asterisk as SIP B2BUA

[Andrew Pogrebennyk]

Hi,

What are the current best practices for running asterisk as SIP B2BUA? 
Are there any sample configs online or the books that detail this 
configuration for the newbies? I'm going to run it behind 1:1 NAT for 
the clients in the public internet so I will use the externip, localnet, 
and nat settings. Thanks,

Andrew
