RE: [Serusers] SER + Prepaid with Radius AAA.

The problem with Vovida's B2BUA is that it has been a dead project for over two years now. It's no longer maintained, and doesn't mesh well with the current state of SIP. As for Asterisk B2BUA, it's a perl-based AGI script. It's not the world's fastest because of that, but it's not slow by any stretch, and because it's a relatively simple language, you could probably modify it (or find a cheap perl coder who could modify it) to suit your needs rather easily.  While Asterisk is not known for its huge numbers of concurrent calls, we use it with a canreinvite=yes and ensure that the RTP traffic never really buffers through the server (which is where the only slowdown actually occurs). You could, if you needed an RTP proxy, conceivably somehow fit RTPproxy into the mix and get more concurrent calls than Asterisk would handle. As for Asterisk B2BUA, it's two things. A patch to the Asterisk code (the patch consists of two additions to the code -- one which allows you to set a variable to only send ONE codec choice through Asterisk (and that portion of the patch doesn't actually work correctly, so it can be scrapped), and one which adds a variable that stores the SIP error code for use in the LCR portion of the Asterisk B2BUA code -- something you could also conceivably do away with if you weren't doing LCR), and the AGI script.  If you want to speed things up, you could rewrite either or both or just use them as a template for your own ideas. The new SEMS code is... well... new. This isn't to say it's bad. Even the old SEMS code worked well in production for its intended purposes, but as of yet, I don't know anyone who uses the new SEMS code in a large-scale production environment. You might be able to jury-rig some sort of solution out of a modified Media Proxy, but I've no idea. There's another solution I know nothing at ALL about which uses Asterisk called AstBill that handles prepaid. There are commercial solutions available. Alepo is one of them, but it's very expensive. It does EVERYthing, but it's very expensive. VPS-43 by the OpenSER people can supposedly do prepaid. Again, I know little about it other than its name. There are probably at least a half dozen others available if you look about. Good luck. :) The trickiest part is actually finding a PSTN terminations provider that understands the concept of customer service. I actually had one the other day tell us, when we informed them they were in breach of contract, that if we were having so many problems, to please find another carrier... so I wish you all the best with your endeavor.
