device. In regards to the volume, it should not matter, we set it based
on what we had seen on a lot of other devices, we should probably make that
pass through in the same way we do duration. I doubt either of these
is the problem. Take a closer look at the pt used for 2833 compared to
what we negotiated, see if anything is amiss there. We have had
people successfully interop with exchange before, if they could chime
in, also, check the wiki as there is a page there.<o:p></o:p></span></font></p>
