Setting up the VCS Expressway
This section describes the configuration steps required on the VCS Expressway.
Configuring DNS and NTP settings
Check and configure the basic system settings on VCS:
1. Ensure that System host name and Domain name are specified (
System > DNS
).
2. Ensure that public DNS servers are specified (
System > DNS
).
3. Ensure that all VCS 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 VCSs you must do this for every peer.
Note: The combination of <System host name>.<Domain name> is the FQDN of this VCS Expressway.
Ensure that this FQDN is resolvable in public DNS.
Ensure that this FQDN is resolvable in public DNS.
If you have a cluster of VCS Expressways, you must ensure that the Domain name is identical on each
peer, and it is case-sensitive.
peer, and it is case-sensitive.
Enabling the VCS Expressway 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.
Ensuring that TURN services are disabled on VCS Expressway
You must ensure that TURN services are disabled on the VCS Expressway used for mobile and remote
access.

1. Go to
Configuration > Traversal > TURN

2. Ensure that TURN services are Off.
Using deployments to partition Unified Communications
services
services
A deployment is an abstract boundary used to enclose a domain and one or more Unified Communications
service providers, such as Unified CM, Cisco Unity Connection, and IM and Presence Service nodes.
service providers, such as Unified CM, Cisco Unity Connection, and IM and Presence Service nodes.
The purpose of multiple deployments is to partition the Unified Communications services available to mobile
and remote access (MRA) users. This enables different subsets of MRA users to access different sets of
services over the same VCS pair. We recommend that you do not exceed 10 deployments.
