I have been following the above thread for sometime now and do I
understand the gist of your arguments. Given what you said, I am
wondering how many VoIP test/monitoring Vendors will actually implement
RAQMON? 

There are some industry heavy weights behind this standard but - correct
me if I am wrong - it appears that there isn't much mass support. A lot
of Vendors seem to have their own proprietary implementation of VoIP
monitoring and one would expect that a standard (RAQMON?) would be a
unifying force. 

Any thoughts/comments would be appreciated.

Thanks,
Danny Lobo
