For details on Verifying External Device Access refer to the Microsoft Office 
Communications Server (OCS) 2007 R2 product documentation:

This step is optional.
If you are not using time.windows.com as your time source, you can configure 
a Windows 2008 / 2003 domain member server as an NTP server. For more 
information, refer to 

Once configured, modify the _ntp._udp.<SIPDomain> SRV record to point to 
the FQDN of the internal NTP server. In some cases, this may require creating 
DNS zone for <SIPDomain>.

Once the environmental dependencies are in place, the next step in the process 
is to upgrade the Polycom CX700 phone’s software from release 1.0.199.123 to 
1.0.522.* (either .101 or .103). (The reason you cannot directly from 1.0.199.123 
to 3.5.6907.35 is because the 1.0.199.123 software does not recognize builds 
greater than 1.0.522.*).

There are three basic steps to this process:

Download the UCUpdates files and uncompress them to CAB files 

Upload the CAB files to the pool and uncompress them further to CPE 
files

Approve the CPE files

In previous releases of OCS 2007, Polycom CX700 phones operating outside the 
firewall connected to the update service by using anonymous access. In this 
release, to enhance security, Polycom CX700 phones by default must use NTLM 
authentication. This means that a user must be logged on to the device with a valid 
user account in order for an external device to connect to Device Update service 
and receive updates.

If your organization has external Polycom CX700 phones that were deployed with 
the previous version of OCS 2007, and you want to use OCS 2007 R2 to update 
them, you must enable Anonymous access for the RequestHandlerExt virtual 
directory in Internet Information Services (IIS). For security reasons, once all 
previously deployed devices have been updated, you should disable anonymous 
access on this virtual directory. OCS 2007 R2 Polycom CX700 phones can be 
updated without Anonymous access.
