I have installed FreeSWITCH on our server, and need some help configuring our FreeSWITCH instance. All of the numbers associated with our FreeSWITCH instance are in the format: 1NPANXXXXXX (where NPA is the area code, and NXXXXXX are the last 7 digits of the phone number).

I need the following configuration:

Calls coming from our IP to IP gateway into our FreeSWITCH instance needs to be routed to the endpoint that is registered with FreeSWITCH
Calls coming from any of the registered SIP endpoints need to be sent to the appropriate destination. The appropriate destination for any number that is not registered with FreeSWITCH is our IP to IP gateway.
Our IP to IP gateway does not require any SIP registration or authentication.
G.729 (but not G.729 Annex B), G.711 mu-law, and G.711 A-law need to be enabled
SIP registrar enabled for registering endpoints other than our IP-IP gateway
SIP traffic needs to be accepted to and from both the IP-IP gateway and from the registered SIP endpoints.

How do I get the above configured in FreeSWITCH?
