I see...
are then voice packets automatically excluded from fragmentation or
should I manually set the fragment size to be bigger then the voice
packets...is the this behavior different for different types of fragmentation
(FRF.12 FRF.11 or cisco)?

Q. on frame relay fragmentation
Because it will introduce extra latency into
the mix, and voice traffic is
latency-sensitive. So you don't want to have
choppy voice.
That and voice packets are typically small enough that it
makes little sense
to fragment them. Fragmentation is done to make all things
play better with
each other on slower speed links. And since voice (or SNA or
some other
stuff) is generally the reason for fragmentation, it wouldn't serve
much
purpose to fragment that traffic as well.

Hi,
I was
reading about frame relay fragmentation and everywhere in the
documentation I
read that voice packets should not be fragmented...
Why is
that?
