And if you're really unlucky, instead of using ISO standards, you have  =

to live in the telecom world where the ITU is the place to go.  ITU  =

standards will often have an Annex -- an add-on that changes the  =

standard completely.

And if it's from ITU it costs big money to get a "real" copy.  And  =

upon receiving it and reading it you find that it describes six  =

different ways to do the same thing, therefore doesn't "define" a  =

standard at all.

Start with ITU H.320, compare to H.323 -- one's ISDN, the other IP --  =

but after that they're the same.  Then try to find all of the  =

appropriate videoconferencing standards underneath H.323.  Then  =

realize that you're looking for an audio answer and the overlying  =

standard just calls out other standards, in this case... it's actually  =

G.729.1 Annex C that you're REALLY trying to find.

And shake your head when you realize that G.729.1 and G.729.1 Annex C  =

aren't even using the same technology or CODEC, but ended up the same  =

number because G.729 was "extensible".

Did the above just this week... because some $20 software client said  =

it did G.729.1 and the customer thought that meant it would do G.729.1  =

Annex C.

And we pay for the privilege of having copies of this slop. :-)
