DMA OperationsGuide MCUs
144 Polycom, Inc.
Signaling address for
SIP The address that the MCU uses for SIP signaling. If you
specify the login information for the MCU, this field is
optional (the system can get the address from the
MCU). If not, and SIP is enabled, this field is required.
Transport type The SIP transport type to use with this MCU. If the
Polycom DMA system‘s security settings don’t allow
unencrypted connections, this must be TLS.
Signaling type Select SIP, H.323, or both, depending on the
configuration of the Polycom DMA system and the
MCU.
Enable for conference
rooms Makes the MCU available as a conferencing resource
for the Polycom DMA system’s Conference Manager.
Up to 64 MCUs can be enabled for conference rooms.
Caution: Before adding an MCU to the DMA system’s
conferencing resources, make sure that MCU isn’t
already a RealPresence Resource Manager system
conferencing resource. The RealPresence Resource
Manager system must have exclusive use of any MCUs
on which it directly schedules conferences.
Enable gateway profiles Makes the MCU available for selection as an ISDN
gateway device and enables the Gateway Profiles tab
for configuring gateway session profiles.
Gateway session profiles indicate to the MCU the
bandwidth parameters to be used for the ISDN
connection. They can be used for:
ISDN gateway calls to the MCU’s direct dial-in
prefix. In this case, the caller specifies the session
profile prefix in the dial string:
<direct dial-in prefix><session profile
prefix><delimiter><E.164 number>
Calls to simplified ISDN gateway dialing prefixes
(see “Add Simplified ISDN Gateway Dialing Prefix
Dialog Box” on page277). In this case, the DMA
system selects the MCU/gateway and its session
profile. See “ISDN Gateway Selection Process” on
page147.
Class of service Select to specify the default class of service and the bit
rate limits for this MCU.
If specified, calls to the MCU use its class of service or
the calling endpoint’s, whichever is better.
Maximum bit rate (kbps) Select the maximum bit rate for calls to this MCU.
