HDX is suddenly experiencing audio and video packet loss when provisioned by RealPresence Resource Manager (RPRM) v10.0.

An issue was found where the HDX may suddenly begin experiencing audio and video packet loss after upgrading RPRM to v10.0.  This happens when the HDX is provisioned by the RPRM and wasn’t occurring prior to the RPRM upgrade.  If the HDX is taken out of provisioning mode, the packet loss previously experienced will disappear, even in calls between the same two endpoints.
This issue is resolved in HDX HotFix v3.1.11_01-53039 (10/5/2016).  The fix is to limit the cryptographic cipher suite list to exclude 2048-bit Diffie-Hellman. Please contact Polycom Support for access to this HotFix.
