Software requirements for Interoperability

• CMA 4000/5000 server – 4.01.02 or higher (see note)

• CMA Desktop – 4.1.1 or higher

• HDX – 2.5.0.5 or higher

Note: The following issues, which may impact VBP functionality exist in CMA 4.01.02. These

issues are addressed in CMA version 4.01.04

• Duplicate Aliases – When a CMAD or HDX in VC2 mode moves from an internal CMA

connection to an external VBP Access Proxy connection you might experience a scenario

where the endpoint cannot connect to the CMA Server. An HDX endpoint is likely in this

state if it displays an indicator stating that the gatekeeper service is down. A CMAD

client is likely in this state if cannot progress beyond the “signing into the media server”

message. In some cases, gracefully logging out of the internal location and waiting at

least 10 minutes before an external login can reduce the chances of experiencing this

issue.

• Dual Redundancy – When deploying 2 VBP’s and 2 CMA server’s for what is called “Dual

Redundancy” if the MASTER CMA server fails, this forces the BACKUP CMA server to

have control of all services, it is possible when this CMA failover happens, this CMA

server may NOT send responses from the VIP (virtual IP) causing messages to be sent

from the physical IP, the VBP is expecting messages to come from the VIP and will not

be forwarded to the remote client. When deploying “Single Redundancy” 2 VBP’s and 1

CMA server, If the MASTER VBP fails, the BACKUP VBP will take over and function as

expected.

Known Issues

• In VOS 9.1.5.1 the Polycom VBP-E series does not support the Access Proxy feature,

although the feature is present in the GUI. VBP-E series platforms will support this feature

in a future release. Access Proxy feature support is fully functional in the VBP-ST series.

• It has been found in the field that 2Wire DSL termination routers have issues with

H.323/H.460 protocols – to date, there is a currently a “single” video endpoint work around,

2Wire configuration parameters can be set on this router to support 1 H.323/H.460

endpoint. Please contact Polycom technical services if you are attempting to use CMA

Desktop, HDX or other H.460 compatible video endpoints behind this device.
