David, This is an almost unimaginably bad idea, and what's worse, it won't even do what you want. No matter how much data you stream constantly to "hold your place", there is just no such feature present in the Internet. Any or all of the packets you send are always subject to being dropped due to congestion. Whatever happened one hour or one minute or one second or even one packet before is, for the most part (excluding routers with route cacheing going on, and all that does is make your 2nd and later packets do ever so slightly better than your first packet), completely irrelevant. Each packet gets forwarded or dropped at each router based pretty much on the conditions that router sees right then; Does it have space on the outbound queue for the chosen interface, etc. So all this scheme will do is cause more lost packets in a global sense. -Dorn _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
