Managing option keys
Options are used to add additional features to the VCS. Option keys can either be valid for a fixed time period
or have an unlimited duration. Your VCS may have been shipped with one or more optional features pre-
installed. To purchase further options, contact your Cisco representative.

The
Option keys
page (
Maintenance > Option keys
) lists all the existing options currently installed on the
VCS, and allows you to add new options.
The
System information
section summarizes the existing features installed on the VCS and displays the
Validity period of each installed key. The options that you may see here include:
n
Traversal Server: enables the VCS to work as a firewall traversal server.
n
H.323 to SIP Interworking gateway: enables H.323 calls to be translated to SIP and vice versa.
n
n
Advanced Networking: enables the LAN 2 port on a VCS, and enables static NAT functionality on a VCS
Expressway.

. This allows VCS to provision endpoints
with configuration information on request and to supply endpoints with phone book information. (Endpoints
including Jabber Video, E20, and the EX and MX Series can request to be provisioned.) Note that the VCS
must use Cisco TMS to obtain configuration and phone book information for distribution.

n
Starter Pack: allows the VCS to offer basic device provisioning without the need for Cisco 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

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

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 the VCS, and these will
each count as one registration.
