Polycom (RMX) 1500 User Manual

Chapter 16-Network Services

Polycom, Inc.

Three Network Traffic Control Flags are added:
•

When the flag is set to NO (default), Network Traffic Control is disabled on the RMX. 

Set the flag to YES to enable Network Traffic Control.

•

This flag regulates the Traffic Control buffer or maxburst size as a percentage of the 

participant line rate. In general, higher traffic rates require a larger buffer. For example, 

if the flag is set to 10 and the participants line rate is 2MB, then the burst size is 

200Kbps.

Default = 10

Flag range: 1-30. 

•

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). 

RMX systems that are part of a DMA environment can benefit from DMA’s SIP Proxy 

Failover functionality.
SIP Proxy Failover is supported in DMA’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 RMX as the IP address of its SIP Proxy.
No additional configuration is needed on the RMX.
Should a SIP Proxy failure occur in one of the DMA servers:
•

The other DMA 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.
