Conference Manager Configuration
Polycom, Inc. 199
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.
