NAT Traversal solution for Opensips Server

I need a VOIP Server for maximum of 1500 simultaneous calls between Android clients and a PSTN network. I installed an Opensips 2.1 server on Ubuntu Server [url removed, login to view] but have these problems:

1. Opensips Clients can call each other but without audio transition. It seems that this is a NAT traversal problem. I installed RTPProxy but could not solve the problem.

2. How can I configure this server with PSTN network?

3. How can implement a prepaid billing for my Opensips using ASTPP? I installed ASTPP but could not connect it to Opensips.

I want you to configure my server and learn me how can I do this myself.
