Expressway MRA Certificates requirements
The Expressway certificates can be generated using the Certificate Sign Request (CSR) option available on
both the Expressway-C and Expressway-E devices. After completing the Installing Cisco Telepresence
Expressway C/E tasks below, the administrator can log into the expressway server via web interface and
using the CSR utility can generate the certificates. Once the certificates are generated it could be
downloaded and be signed by the appropriate Certificate Authority for authentication purposes.
Expressway-C server certificates can be signed by an private CA or optionally by third party public trusted
CA
Expressway-E server certificate must be signed by a third party public trusted CA only. Additionally if a DX
or 7800/8800 series phone is used for MRA then need to ensure that Expressway-E server certifcate is
mandatorily signed by one of the third party public trusted root CA's that's embedded into the endpoint
device platform OS certifcate store.
Below table shows Expressway certificate signing request tool prompts for and incorporates the relevant
Subject Alternate Name (SAN) as appropriate for the Unified Communications feature to be deployed on
the Expressway.
