Configuring Encryption Settings for Integration with Microsoft Office
Communications Server 2007 R2 and Microsoft Lync Server 2010
Polycom HDX systems use the SRTP standard to support media encryptions
in calls with Office Communicator. The encryption settings for each
component also affect the ability to place encrypted calls.
Both the Microsoft Office Communications Server or Lync Server pool and the
Polycom HDX system need to be configured to support encryption in order for
calls to connect with encryption. If both components have encryption turned
off, calls connect without encryption. If one component is set to require
encryption and the other is not, calls fail to connect.
Calls from a Polycom HDX system to a Polycom RMX system using Microsoft
Office Communications Server or Microsoft Lync Server require that the
Polycom HDX system have encryption set to When Available.
For more information about encryption configuration in a Microsoft Office
Communications Server or Microsoft Lync Server environment, refer to the
Polycom Unified Communications Deployment Guide for Microsoft Environments.
Setting Password Policies
You can configure password policies for Admin, User, and Meeting
passwords. These password settings can ensure that strong passwords are
used.
To configure password policies:
1 Do one of the following:
— In the local interface, go to System > Admin Settings > General
Settings > Security > Password Settings (select if necessary).
— In the web interface, go to Admin Settings > General Settings >
Security > Password Settings.
2 Select Admin Room Password, User Room Password, Meeting
Password, or Remote Access Passwords.
Changes to most password policy settings do not take effect until the next
time the password is changed. Changes take effect immediately for
Minimum Password Age in Days, Maximum Password Age in Days, and
Password Expiration Warning in Days. Changing Minimum Length from
Off to some other value also takes effect immediately.
When Use Room Password for Remote Access is enabled, the room password
policy is applied to both room and remote access passwords.
