Expressway-C and Expressway-E, and how to discover the Unified CM servers and IM&P servers used by
the service.
Note that this deployment requires valid certificates on both Expressway-C and Expressway-E. If XMPP
federation is to be used, the IM&P servers need to be discovered on the Expressway-C for all the relevant
information to be available when generating certificate signing requests.

Setting up the Expressway-C
This section describes the configuration steps required on the Expressway-C.
Configuring DNS and NTP settings
Check and configure the basic system settings on Expressway:
1. Ensure that System host name and Domain name are specified (
System > DNS
).
2. Ensure that local DNS servers are specified (
System > DNS
).
3. Ensure that all Expressway systems are synchronized to a reliable NTP service (
System > Time
). Use
an Authentication method in accordance with your local policy.
If you have a cluster of Expressways you must do this for every peer.
Configuring the Expressway-C for Unified Communications
Enabling mobile and remote access

1. Go to
Configuration > Unified Communications > Configuration
.
2. Set Unified Communications mode to Mobile and remote access.
3. Click Save.
