Thanks for your msg. We’re developing it for someone else.

It’s like this. Our client buys bulk time from international carriers. Then they sell wholesale time to ISP’s etc, who sell it to the customers.

We need to track the call traffic so that our client can bill the wholesale buyers as well as the end-users.

Call flow is like:
1. IP-IP calls using IP phones
2. IP-PSTN calls, using IP phones
3. Prepaid calling card calls

For the time being, assume that calling card is routed to a calling card partner. So, most probably they’ll handle the billing for it.

IP-Phone to IP Calls
Call is sent over IP network, comes to our network, is routed back to the called IP.

IP-Phone to PSTN Calls
Call is sent over IP network, comes to our network, is routed back to the called PSTN number.

We need to capture these calls and maintain billing records.

Here is the latest configuration that I have received:
Pix 515 (firewall)
Cisco 7206 VXR (NPE300)
Cisco 5814 (capacity 2 DS3’s & 12 T1’s)

Hope now it makes more sense to you. See if you can guide me with the design/development in this scenario.

Thanks.
