I have a question i believe i know the answer to but... I need to double check
Our corporate VC infrastructure is POLYCOM RMX1500+ with polycom CMA servers. we have a unit at a smaller office which is an old model the PVS-1619 i suspect it is too old to connect to virtual room as we haven't been able to upload the address book from the corporate infrastrucutre.
You are somewhat correct. The older Viewstation will not download the directory from CMA however it should be able to connect to the RMX room. You may need to manually create a directory entry locally in the Viewstation that gets it to the RMX room.
