The idea of a B2BUA is even more revolting when you consider that the overwhelming preponderance of people who have a topology concealment need have business models based solely on information asymmetries and arbitrage. If the only thing you've got going for you is that you can buy at one price and sell at an ever-so-slightly higher one, you should do something else.
But that doesn't stop people from a) thinking there's money in it and b) going to OpenSIPS when they find Kamailio doesn't give them what they want. There is also the matter of 'topoh'. It's one of those things that, in theory, should work well for this case, but in practice often doesn't, perhaps due to lack of proper RR support on all sides in all cases. I can't really say why, I just know that when I've tried to deploy it for customers that insist on fitting some sort of "topology condom" over their switch platform, it's led to call duration and billing reconciliation differences in the thousands of USD. -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ Sent from my BlackBerry. _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
