<DIV dir=ltr align=left><SPAN class=843453312-13122005><FONT face=Arial
color=#0000ff size=2>The one thing that concerns me about your setup listed
below is that it is all L2. One spanning tree problem (or even simple
reconvergence) could seriously mess up your voice network. I'd consider
some readdressing and a move to L3 between your "WAN" links to help prevent
problems, and you definitely have the hardware to handle
this.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=843453312-13122005><FONT face=Arial
color=#0000ff size=2>I don't recommend using policing for any voice traffic
(particularly CallManager). Marking voice and CallManager traffic
according to the SRND has been enough for me in the past. In your case
with an all-switch network, the recommended queue depths on the 100MB links
should be sufficient (assuming latency is currently good)

there are two 100MB hops between the CallManagers, and in the worst case
(redundant path) two 10MB hops. I’m a little bit worried about that and I
would like to configure QoS. We have a bunch of devices between the
