RMX 2000 : Do i upgrade to 7.8 or 8.1 ?

Hi All,

we currently have RMX 2000 version , CMA version 5.3.0.ER15 and DMA  4.0.3_P3_Build_17

I want  to do the following:


1.change the exisitng E1 link we have from RMX  to CUCM version 8.6 to a SIP trunk
2. move eventually to single dial plan between CUCM and RMX
3. support SVC
4. keep stable platform for video calls

I know the RMX needs to be upgraded to a minimum of 7.8 for  SVC support but is this our best option or do I need to go to 8.1 ? and what upgrades do I need to make on CMA and DMA if any ?

Hello DoctorC,

welcome to the Polycom Community.

I had already responded to your Email and I am aware that you are already working with the correct team within Polycom in order to plan such complex update.


As far as I am aware the SVC option only works with a RMX which has a MPMx card. In addition certain license requirements are pre-requisite to upgrade to a later version, i.e. you need to have a key or purchase an upgrade.


The CMA should be running 6.2.0, at least that is what RMX 8.1 has been tested against. In addition the DMA was tested in Version 6.0.2.


Call manager was validated against version 9.0 or 9.1 but I doubt there is a big difference. The SIP trunk should be either UDP or TLS.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
