This command displays all configuration data and real-time data for
the H.323 Service.

Delivering H.323 Incoming UUI to a Unified ICME Routing Script

The UUI extracted from the incoming call is passed to the Unified ICME scripting environment
by the Unified CVP Call Server. This feature enables capturing data from an external system
(for example, caller-entered digits from a third-party IVR) and passing that data to Unified
ICME on a new call. This can be accomplished by populating the UUS parameter (often known
as the UUI) in the IAM message of the GTD (Generic Transparency Descriptor) data that is
sent to the gateway from the network in the Q.931 setup message. The gateway and Unified
CVP can extract this data and send it to Unified ICME on a new call.

Additionally, other parameters in the GTD can also be extracted and sent to Unified ICME if
the user chooses. Any parameter contained in the NSS IAM message can be extracted as long
as the ingress IOS gateway also extracts it. Refer to 

for a description of all the GTD fields IOS 12.4 will extract. Also, refer to the ITU-T Narrowband
Signaling Syntax spec (Q.1980.1) for a detailed description of the IAM message. This feature
is available in Unified CVP Comprehensive and VRU-Only call flow models and can be used
with any Unified CVP VRU type.

How it Works

The external system inserts the desired values into the dat field of the UUS parameter of the
NSS IAM message. These NSS messages are used as the basis for building the GTD data that
ultimately arrives at the IOS gateway from the PSTN. Note that the UUS dat field is represented
by pairs of hexadecimal digits. This means that if the external system wants to pass "12345" in
the UUS dat field, it will arrive to the gateway with the following representation: "3132333435".
By default, this 2-byte hexadecimal value is passed to Unified ICME. The Unified ICME script
must manipulate this value using the Formula Editor. The user can specify an option on the
gateway or the Unified CVP H.323 Service to convert to the 1-byte ASCII representation (that
is, "12345") before passing to Unified ICME.

Any data that cannot be represented by a printable ASCII character will be replaced with a "."
character. Therefore, if the incoming GTD data from the network contains binary data (such as
counters), this option should not be used since it will result in a loss of valuable information.
Additionally, other fields from the IAM message can also be utilized, if desired.

How that data moves from the gateway to the Unified ICME differs depending on the deployment
model used. The format in which the data appears in Unified ICME will also be somewhat
different based on the deployment model. In any case, Unified ICME 7.1(1) and beyond will
accommodate a maximum length of 131 characters. Before that release, Unified ICME will
only accommodate a maximum length of 36 characters.
