After reading this forum:
http://www.voipuser.org/forum_topic_4468.html
it made me wonder, whether or not you really need B2BUA if you already have Mediaproxy in your environment. I know the purpose of Mediaproxy is to help with NAT situations. However, given the fact that Mediaproxy is always in the media path, couldn't it be ALSO used to "terminate" a call in progress, the same way that B2BUA can? And by B2BUA I refer to the Asterisk B2BUA, all within the context of prepaid type services.
Any comments?
Thanks, Daniel
