● TC_LATENCY_SIZE - 

This flag limits the latency (in milliseconds) or the number of bytes that can be present in a queue.
Default = 500
Flag range: 1-1000 (in milliseconds). 

Collaboration Server systems that are part of a RealPresence DMA system environment can benefit from 
the RealPresence DMA system’s SIP Proxy Failover functionality.

SIP Proxy Failover is supported in the RealPresence DMA system’s Local Clustering mode with redundancy 
achieved by configuring two DMA servers to share a single virtual IP address.

The virtual IP address is used by the Collaboration Server as the IP address of its SIP Proxy.

No additional configuration is needed on the Collaboration Server.

Should a SIP Proxy failure occur in one of the RealPresence DMA system servers:

● The other RealPresence DMA system server takes over as SIP Proxy.
● Ongoing calls may be disconnected.
● Previously ongoing calls will have to be re-connected using the original IP address, registration and 

connection parameters.

● New calls will connect using the original IP address, registration and connection parameters.
