Installing Expressway security certificates and setting up a
secure traversal zone
secure traversal zone
To support Unified Communications features (such as mobile and remote access or Jabber Guest), there
must be a Unified Communications traversal zone connection between the Expressway-C and the
Expressway-E. This involves:

Installing suitable security certificates on the Expressway-C and the Expressway-E.

Note that 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.
Enabling the Expressway-C for mobile and remote access
To enable mobile and remote access functionality:
1. Go to
Configuration > Unified Communications > Configuration
.
2. Set Unified Communications mode to Mobile and remote access.
3. Click Save.
