Hello,

for calling card system you need a back-to-back user agent able to do IVR. OpenSER is not such application, so you have to use Asterisk or other b2bua here. You can use OpenSER to do all the other tasks (registration, nat traversal maintenance, authentication and authorization, ...) and let the Asterisk do only the IVR/Calling card part. OpenSER scales better in terms of subscriber population, and you can use it as frontend to an Asterisk farm -- openser can do loadbalancing between them (see dispatcher module).

For postpaid, you can get from OpenSER the CDRs, and then feed a postpaid billing engine to rate them (see acc module).

Cheers, Daniel
