Polycom CX700 Phone Upgrade Steps - Summary

Upgrading Polycom CX700 Phone within a Microsoft Office Communications Server 2007 R2 Environment
When looking through a NetMon trace from an upgrade to 1.0.522.101, you may
notice that the DNS query for ucupdates-r2.<DHCPDomain> does not occur until
the CPE.NBT file had already started streaming to the OCPE device. This happens
when you sign into the phone prior to the upgrade starting; if you do not sign in, the
DNS query would have occurred at the beginning of the trace.
If your environmental dependencies are close to being set and you just want a
high level checklist of the steps involved in configuring Microsoft Office
Communications Server (OCS) 2007 R2 to upgrade from release 1.0.199.123 to
1.0.522.101 and then to 3.5.6907.35, the following is a summary of the steps. For
more details, refer to the next section,
