<p class=MsoNormal>We have a scenario with Callmanager 4.2 – PUB &
SUB separated by MPLS – plenty of bandwidth but QoS/CoS is our issue. I
have a copy of the “Cisco Unified Callmanager 4.2 TCP and UDP Port Usage”
guide, but unfortunately due to considerations outside of our control we cannot
prioritize by IP nor can we prioritize all of the CM to CM ports listed in the
above guide. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In the following SRND: <o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>under the “WAN Considerations” section (that I
linked to in the above link) it discusses ICCS (Intra-Cluster Communication
Signaling) between servers. It links to a subsection of “Intra-Cluster
Communications” that vaguely lists what communications are involved in
ICCS but doesn’t discuss actual ports.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>So basically my issue is this: I’m looking for is a “meat
and potatoes” list of the absolute necessary ports to prioritize that must
meet the 20 ms delay (40 ms RTT) between intra-cluster callmanager boxes to
keep them happy.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>As always, if anyone can offer guidance/assistance, it would
be greatly appreciated. <o:p></o:p></p>
