Hello techchetn,
welcome to the Polycom Community.
Did you check the release notes for RPD 3.0 as they contain the following:
A known issue on RPD and RPM version 3.0 on content is if you create a Continuous Presence (CP) only conference call on a Polycom® RMX® 4000/2000 system and RMX/Polycom® RealPresence® Collaboration Server 800s version 8.1 with default content settings (Content Settings: HiResGraphics and Content Protocol: H.264 HD), the RPM/RPD application cannot send or receive content if call rate is set as 384 kbps or below.
Workarounds are:
- Change the RMX Content Settings to Graphics and Content Protocol to H.263 & H.264 Auto Selection
- or set the call rate on RPM/RPD to above 384 kbps
Does above match your scenario as I am unsure if it is applicable to the RMX running 7.8?
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
