Option keys
The
Option keys
page (
Maintenance > Option keys
) lists all the existing options currently installed on
the VCS, and allows you to add new options.
Options are used to add additional features to the VCS. Your VCS may have been shipped with one or
more optional features pre-installed. To purchase further options, contact your Cisco representative.

The System information section summarizes the existing features installed on the VCS. The options
that you may see here include:
that you may see here include:
n
Expressway: enables the VCS to work as an Expressway™ firewall traversal server.
n
H.323 to SIP Interworking gateway: enables H.323 calls to be translated to SIP and vice versa.
n
FindMe™: enables
functionality.
n
Dual Network Interfaces: enables the LAN 2 port on your VCS Expressway.
n
Device Provisioning: allows VCS to provision endpoints with configuration information on request and
to supply endpoints with phone book information. (Endpoints including Movi v2.0 or later, and E20 v2.1
or later can request to be provisioned.) Note that the VCS must use TMS as its external manager to
obtain configuration and phone book information for distribution.
to supply endpoints with phone book information. (Endpoints including Movi v2.0 or later, and E20 v2.1
or later can request to be provisioned.) Note that the VCS must use TMS as its external manager to
obtain configuration and phone book information for distribution.
n
Starter Pack: allows the VCS to offer basic device provisioning for a range of endpoint device types,
including Movi users, without the need for TMS (see

).
n
Traversal calls: determines the number of traversal calls allowed on the VCS (or VCS cluster) at any
one time. Note that traversal calls that are passing through the VCS from one neighbor to another but
where neither endpoint in the call is locally registered will still be counted as one traversal call. See the
one time. Note that traversal calls that are passing through the VCS from one neighbor to another but
where neither endpoint in the call is locally registered will still be counted as one traversal call. See the
section for more information.
n
Non-traversal calls: determines the number of non-traversal calls allowed on the VCS (or VCS cluster)
at any one time. Note that non-traversal calls that are passing through the VCS from one neighbor to
another but where neither endpoint in the call is locally registered may or may not require a non-
traversal call license, depending on the
at any one time. Note that non-traversal calls that are passing through the VCS from one neighbor to
another but where neither endpoint in the call is locally registered may or may not require a non-
traversal call license, depending on the
setting. Note that a non-traversal call on a
VCS Expressway will consume a traversal license if there are no non-traversal call licenses available.
n
Registrations: the number of concurrent registrations allowed on the VCS. An endpoint can register
with more than one alias and this will be considered to be a single registration. However, an endpoint
that supports both SIP and H.323 and registers using both protocols will count as two registrations.
H.323 systems such as gateways, MCUs and Content Servers can also register with a VCS, and
these will each count as one registration.

n
TURN Relays: the number of concurrent TURN relays that can be allocated by this VCS (or VCS
cluster). See
cluster). See
for more information.
n
Encryption: indicates that AES (and DES) encryption is supported by this software build.
n
Advanced account security: enables
features and restrictions for high-security
installations.
n
Enhanced OCS Collaboration: enables encrypted calls to and from Microsoft OCS/Lync Server (for
both native SIP calls and calls interworked from H323). Note that as the VCS must process the media
in both scenarios, a traversal call license will be used. This option key is also required by the B2BUA
for it to use
