[cisco-voip] lync moc desktop p2p & p2m video calls , conferencing

[Scott Voll]

Are you doing a pilot of both M$ and Ci$co?  Comparing the two?

1.  M$ can do  the same stuff that CM does.  It does not have to be
configured together to get it working.

2.  I think it depends on what your planing to end up with.  are you
planning on integrating the two?

3.  Not really sure.  Someone told me (YMMV) that MS just pushes more
packets if it starts loosing packets.  Can fill up pipes if its having
issues getting the packets through.  Don't know if it's true or not.

4.  & 5.  I don't know.
