Configuring mobile and remote access on VCS
This section describes the steps required to enable and configure mobile and remote access features on
VCS Control and VCS Expressway, 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 VCS Control and VCS Expressway. If XMPP
federation is to be used, the IM&P servers need to be discovered on the VCS Control for all the relevant
information to be available when generating certificate signing requests.
Setting up the VCS Control
This section describes the configuration steps required on the VCS Control.
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 local 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.
Configuring the VCS Control for Unified Communications
Enabling 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
.
Note that you must select
Mobile and remote access
before you can configure the relevant domains and
traversal zones.
Configuring the domains to route to Unified CM
You must configure the domains for which registration, call control, provisioning, messaging and presence
services are to be routed to Unified CM.
1. On VCS Control, go to
Configuration > Domains
.
2. Select the domains (or create a new domain, if not already configured) for which services are to be routed
to Unified CM.
3. For each domain, turn
On
the services for that domain that VCS is to support. The available services are:
l
SIP registrations and provisioning on VCS
: the VCS is authoritative for this SIP domain. The VCS
acts as a SIP registrar and Presence Server for the domain, and accepts registration requests for any
SIP endpoints attempting to register with an alias that includes this domain. The default is
On
.
