Conference Manager Configuration

Field

Description

 

 

Line rate

The maximum bit rate at which endpoints can connect to conferences using

 

this template.

 

If Video switching is selected, the minimum line rate is 768 kbps (except for

 

SD resolution, available only on v7 and newer Polycom MCUs with MPM+ or

 

MPMx cards).

 

 

Audio only

Sets the conference to be audio only. This limits line rate to a maximum of

 

128 kbps and disables numerous video settings.

 

If the MCU selected for a conference doesn’t support audio-only

 

conferencing, this setting is ignored. To ensure that conferences based on an

 

audio-only template are audio only, do one of the following:

 

Set the audio-only template’s Line rate to 64 kbps.

 

Associate conference rooms (VMRs) that specify the audio-only template

 

with an MCU pool order that contains only MCUs supporting audio-only

 

conferences.

 

If the MCU supports audio-only conferences but audio ports aren’t available,

 

video ports are consumed. See the documentation for your RealPresence

 

Collaboration Server or RMX MCU for detailed data regarding audio-only

 

conferences and resource usage.

 

 

Advanced Settings

 

 

 

Encryption

Specifies the media encryption setting for conferences using this template:

 

No encryption — All endpoints join unencrypted.

 

Encrypt when possible — Endpoints supporting encryption join encrypted;

 

others join unencrypted.

 

Encrypt all — Endpoints supporting encryption join encrypted; others can’t

 

join.

 

Note: VMR dial-outs to H.323 endpoints from an encrypted RealPresence

 

DMA system conference are unsupported and will not connect.

 

Note: Prior to v7.2, RMX MCUs supported only encryption settings of On and

 

Off. If such an RMX is selected for a conference, the settings Encrypt when

 

possible or Encrypt all are both converted to On.

 

Consult the MCU’s Administrator’s Guide for the version in question for

 

detailed information about media encryption (SRTP).

 

Media encryption may be required in a maximum security environment.

 

 

LPR

Enables Lost Packet Recovery for conferences using this template. LPR

 

creates additional packets containing recovery information that can be used to

 

reconstruct packets lost during transmission.

 

 

TIP compatibility (v7.6)

Enables compatibility with Cisco’s Telepresence Interoperability Protocol,

 

either for video only or for both video and content. Conferences can include

 

both endpoints that don't support TIP and Cisco TelePresence® System

 

(CTS) endpoints. If Prefer TIP is selected, TIP content is used for endpoints

 

that support TIP, and non-TIP content is used with non-TIP endpoints.

 

Requires minimum line rate of 1024 kbps and HD resolution (720 or better).

 

Available only on v7.6 and newer Polycom MCUs.
