B2BUA will give you more control. FreeSwitch is great choice.<br><br>You can look at this project: <a href="http://vbilling.org/">http://vbilling.org/</a><br><br>I did not try it myself but it looks interesting and if it stable enough it can can fit in your setup.<br>

<font size="-1"><font face="Arial">Hi all,<br>
<br>
I'm working in a project for a service provider in which prepaid
is an essential requirement. They have about 12000 subscribers.<br>
The core infrastructure will be Kamailio+RTPProxy while I have
some doubts about the prepaid feature. I'm thinking about a
B2BUA (SEMS or Freeswitch) that is called if the user belong to
a "prepaid group" and perform authorization and accounting; in
this case the SIP flow could be: Kamailio -> B2BUA(Prepaid)
-> Kamailio. Is a good choice?<br>
<br>
At the moment I cannot estimate the effort needed to develop
this section (base prepaid feature) of the project... Do you
have some hints?<br>
<br>
What are the prepaid solution implemented by you? Do you use
your own developed solution or do you think that is better to
choose a commercial solution (that provide also calling-card and
other features)?<br>
I have seen some commercial products (Portabilling,
Jerasoft/Bilberry, ...); what do you think about?<br>
<br>
<br>
Best Regards,<br>
<br>
