Trust list:
You cannot modify the root CA trust list on these endpoints. Make sure that the Expressway-E's
server certificate is signed by one of the CAs that the endpoints trust, and that the CA is trusted by the
Expressway-C and the Expressway-E.

Bandwidth restrictions:
The Maximum Session Bit Rate for Video Calls on the default region on Cisco
Unified Communications Manager is 384 kbps by default. The Default call bandwidth on Expressway-C is also
384 kbps by default. These settings may be too low to deliver the expected video quality for the DX Series.

(Preview) Multiple Presence Domains / Multiple IM Address Domains via MRA
Jabber 10.6 can be deployed into an infrastructure where users are organized into more than one domain, or into
domains with subdomains. This requires IM and Presence Service 10.0.x (or later).
domains with subdomains. This requires IM and Presence Service 10.0.x (or later).
Limited testing has shown that this feature works via MRA. Hence this feature is in preview with Expressway X8.5.1
and later, pending further testing and full support in a future version of Expressway.

Note:
This feature is distinct from the multiple deployments feature released in X8.5. That feature is limited to one
domain per deployment, where all IM and Presence Service clusters within a deployment serve a single domain. This
feature is different because it concerns MRA support for all IM and Presence Service clusters within a deployment
serving a common set of one or more Presence domains.

Each new domain impacts the Expressway’s performance. We currently recommend that you do not exceed 50
