Packet loss
compensation
(LPR and DBA)
Enables Lost Packet Recovery (LPR) and Dynamic Bandwidth Allocation (DBA).
• LPR creates additional packets containing recovery information that can be used to
reconstruct packets lost during transmission.
In CP Conferences, LPR is enabled by default while in VSW Conferences, LPR is disabled
by default. LPR can be enabled for VSW conferences but H.320 and SIP participants will
not be able to connect.
• DBA allocates the bandwidth needed to transmit the additional packets.
Auto Terminate Not available when Operator Conference is enabled. Not recommended for SVC Only
conferences.
When enabled, the MCU automatically ends the conference when the specified termination
conditions are met. Terminate conditions include:
• Minutes Before First Joins
• Minutes At the End
After last participant quits

Auto Redialing Enables the MCU to automatically redial H.323 and SIP participants that have been
abnormally disconnected from a conference.

interrupting with their own content while the current content stream is active.
Enable FECC When enabled, participants can control the zoom and PAN of other endpoints in the
conference via the FECC channel.
FW NAT Keep
Alive
Specifies that when receiving calls through a firewall or session border controller (SBC), the
