[asterisk-dev] Codec Framing/Packetization limits

[Dan Austin]

I posted a small document to Mantis yesterday to explain the
usage and capabilities of the new RTP packetization options.

It was quickly pointed out that the max values for many of the
codec are lower than (what's the right word, reasonable? possible?
viable?).  In any case here is a table of the current values.
These values were picked based on what authoritative documentation
that could be found, including RFCs and a number of Cisco whitepapers.
While these values might be lower than any theoretical maximum, I think
they are safe/practical values.

Name            Min             Max             Default

g723            30              300             30              30

g729            10              230             20              10

Any comments or suggestions about any of the values would be
appreciated,
but I am most interested in what the Max values should be for each
codec.

Thanks,
Dan
