Do ‘show http client cache’ on the gateway. The 'Fresh Time' column equals the refresh time
period set on the HTTP media server. For example, if the refresh period was set to 15 minutes,
it says 900 seconds. The 'Age' column shows how many seconds have passed since the prompt
was last refreshed. In general, this number will be less than the 'Fresh Time'. However, if no
call has ever accessed the prompt recently, this number could be greater than the fresh time.
Prompts are only refreshed when triggered by a call and the prompt 'Fresh Time' has expired.
If the Fresh Time is a very high value, the only way to remove the prompt from cache is to
reload the gateway.

Incoming UUI to be Used as the Correlation ID
Unified CVP uses the User-to-User Information (UUI) from the incoming call as a Correlation
ID in the VRU-Only call flow model. This feature allows customers to transfer Correlation IDs
through their network, for example, when using a Call Routing Service Protocol (CRSP) NIC
for call control.

through their network, for example, when using a Call Routing Service Protocol (CRSP) NIC
for call control.
Note: This feature applies only to the Unified CVP VRU-Only call flow model.
The network typically has no place to store a Correlation ID so it must be "hidden" in the ISDN
setup that arrives at the IOS gateway and then extracted by the gateway. The UUS parameter
(often known as the User-to-User Information (UUI) of the Generic Transparency Descriptor
(GTD) data) can be used to "hide" the Correlation ID, provided the call control client has the
capability of inserting a Correlation ID value into the GTD.

and appends it to the DNIS before sending an HTTP request to the Type3 Unified CVP Call
Server.
How It Works
The call control client (such as the CRSP NIC) inserts the desired Correlation ID value into the
dat field of the UUS parameter of the NSS IAM message. These NSS messages are used as the
basis of building the GTD data that ultimately arrives at the IOS gateway from the PSTN. Refer
to the ITU-T Narrowband Signaling Syntax spec (Q.1980.1) for a detailed description of the
IAM message and UUS parameter, included below for convenience. Note that the dat field
contains pairs of hexadecimal digits. This means that if the Correlation ID is "12345", the dat
field must be populated as "3132333435". The gateway bootstrap.tcl script converts back to
"12345" before appending to the DNIS and passing to the Unified CVP Call Server in the HTTP
URL.
