Not sure how you would do this on Asterisk, but what I am doing with mine (billing by IP) is replacing the from header in the SIP INVITE with a pre-paid account number for the customer. You will need to load the UAC module for this, then do something like

 

if (src_ip=xxx.xxx.xxx.xxx)

{

  uac_replace_from("sip:PREPAIDACCTNO@foobar.com");

}
 

This means that any calls made inbound to OpenSER from that IP address will have the account number replaced with the pre-paid account number. How you do billing is then up to you - whether using the Acc module or whether something can be done on Asterisk, or even a third-party application. I have heard Asterisk can send DIDs. You can then do something similar for inbound DIDs from Asterisk.

 

Just beware this has some rather obvious security issues, so as a start, you can try having the customer add a prefix to their local account numbers which you can then authenticate against. If anyone knows of a better way, please don't hesitate to share.
