Media Manager user policy settings
You can grant or limit access to media features by enabling or disabling various policies for users. Sametime® Media Manager policy changes take effect in 60 minutes by default.
You can change the default time that Instant Messaging and Media Manager policies take effect by editing the REFRESH_RULES_INTERVAL setting in the [policy] section of the sametime.ini file.
All unauthenticated users will have the anonymous policy, Media Manager Anonymous Policy, applied to them. For authenticated users, Sametime searches for a user ID or group match, and then applies the highest weighted policy. If there is no match for an assigned default policy, the Media Manager Default Policy is applied.
In a deployment with multiple Sametime communities, most policies are applied when a user logs in to any community. Updated or new Conference Template settings are applied after any cached objects expire, or the servers are restarted. Some policies are applied only when the client logs in to the default community. The following tables flag those policies that are applied only when users log in to their default communities.
Setting | Purpose | Default Policy | Anonymous Policy | Applies to Default Community Only? |
---|---|---|---|---|
Allow access to third-party service provider capabilities from contact lists, instant messages, and meetings | Allows outside vendors to provide audio and video for instant messages and instant meetings. This setting does not apply to browser meetings. | Not selected | Not selected | No |
Allow changes to preferred numbers | This setting displays only if Allow
access to third-party service provider capabilities from contact lists,
instant messages, and meetings is selected. If this setting is not selected, users cannot add telephony devices, and the administrator controls which devices can make or receive calls in the system. |
Selected | Selected | No |
Voice and video capabilities available through the Sametime Media Manager: | Allows users to use computer audio and video
in instant messages and instant meetings. Choices are:
This setting does not apply to browser users. Use the next setting instead. |
Audio and video | Audio and video | No |
Allow Audio/Video use in the web browser | Allows users to have audio-video capabilities in Sametime Meetings from a web browser. | Selected | Selected | No |
Allow access to service provider for internal audio and video conferences | Allows access to internal service provider for audio and video conferences. Users cannot make multiway or conference calls if this is disabled. | Selected | Selected | No |
Enable encryption for the client | Encryption level for service provider conferences
using Secure Real-time Transport Protocol (SRTP) Encryption. Note
that the application of these choices are impacted by the Conference
Template encryption setting. Choices are:
Important: Use the same setting for the Default User
Policy and the Anonymous User Policy. Anonymous users joining a conference
must have encryption settings that are compatible with the default
conference template, or they will not be able to join the call. |

Video resolution | Video quality is affected by the available network
bandwidth. The higher the video resolution, the more bandwidth is
required and the better quality. The Sametime video codec automatically
adapts to the available bandwidth and reduces the bit-rate to a certain
threshold for each chosen video resolution. However, the quality suffers
when the available bandwidth becomes too low, especially during peak
utilization when the contention in the network routers causes packet
loss. The video resolution is composed of the following elements:
For details see Video resolution bandwidth requirements. Note: You can use this setting in a mixed Sametime pre-9.0
and 9.0 client deployment. This setting applies only to pre-9.0 clients, therefore, in a mixed
environment the setting only impacts the pre-9.0 clients. The Sametime 9.0 clients are not affected. See Table 5 in this
topic for information about resolution settings for a mixed-version deployment. |
CIF352x288@15fps 384kbps | CIF352x288@15fps 384kbps | No |
Client line rate | The maximum allowed line rate. For person-to-person
calls, the higher the line rate, the better the resolution. For a
conference the higher line rate provides higher resolution, and also
allows more streams. This line rate overrides the client policy only when a conference is used. It is recommended that you set the same value for the conference line rate, the client line rate and the mobile client line rate. Note: This setting applies only to Sametime 9.0 clients. |

Allow changes to the permanent call routing rule | If this setting is not selected a lock icon appears for this rule in the user's preferences. "Allow access to third-party service provider capabilities from contact lists, instant messages, and meetings" must be selected to specify this setting. This setting does not apply to browser users. |
Selected | Selected | No |
Allow use of "Offline" status in call routing rules | Allows users to add their own devices to make
and receive calls. "Allow access to third-party service provider capabilities
from contact lists, instant messages, and meetings" must be selected
to specify this setting. This setting does not apply to browser users. |

on mobile devices. Choices are:
|

Allow Mobile Client Video on WiFi only | Use this setting for low bandwidth capability for mobile data. | Not selected | Not selected | No |
Call Line Rate for Mobile Client | The maximum allowed line rate for a mobile conference. Tip: It is recommended to set the same value for the conference
line rate, the client line rate and the mobile client line rate. |

Not applicable | Not applicable | Not applicable |
Conference Mode | Sets conference line rate based on client deployment. Choices are:
|
Mixed AVC and SVC | Not applicable | No |
Conference Mode Experience | Available only if Conference Mode is
set to Mixed AVC and SVC. This setting determines
the video resolution pairing between Sametime 9.0 (SVC) and Sametime 8.5.2 (AVC) clients
in a conference. By default, the 8.5.2 client is configured to receive
the lowest video resolution stream available from remote 9.0 clients.
If you increase this resolution, number of video streams possible
decreases because of the high bandwidth and processing requirement
for decoding video on the 9.0 client. If the client line rate is
below the minimum required for a given conference type, the call will
be audio only. See Table 5 for Conference Mode Experience resolution
specifications for these choices.

Conference Line Rate | Sets the maximum allowed line rate for the conference. Tip: It is recommended to set the same value for the conference
line rate, the client line rate and the mobile client line rate. |

Encryption | Sets encryption for the conference. However,
as noted in the following options, encryption behavior is impacted
if client encryption settings (Table 1) differ from conference encryption.
