Thanks Sasa,
Well this will help me to calculate. Where you got all these stats ? are
they in the same book that you have reffered, can u tell me the Author and
publication also.
Can we have RTP compression at 2 Internet routers if they are connected Via
Internet ?
Moreover normally delay is 500 msec or something on internet, and if you
have ever done a voice chat on msn or yahoo when we are on dialup, things
work perfectly. So that made me think that VoIP should work perfectly on
Internet based leased lines.
