| Description | The H.323 Service table lists each Customer Voice Portal
(CVP) H.323 service configured on this server. This service
is a software component which always resides on the CVP Call
Server. The CVP H.323 service interacts with the CVP IVR
service to relay call arrival, departure and transfer
instructions between it and other H.323 devices.
The CVP H.323 service is a legacy service used only in H.323-
based deployments. Although this service started as a true,
albeit incomplete, voice browser, its strength was its
ability to effect complicated H.323 call control activities
with the Gateway and the Cisco Call Manager. Over time, the
VXML Gateway's IOS voice browser supplanted it as a voice
interaction device and call control became its main focus.
SIP is still a young protocol compared to H.323 and there are
still certain capabilities which either the gateway, the Call
Manager or the protocol itself does not yet support. Users
who require these capabilities, as well as those who wish to
upgrade without switching from H.323 to SIP will therefore
continue to use the CVP H.323 service in place of the CVP SIP
service.
This table has a sparse dependent relationship with the
Service table. The service index acts as the primary
index, relating the entry to the corresponding entry in the
Service table.
The SNMP agent constructs this table at startup. Since
services can only be added or deleted when the CVP
application is stopped, service information table entries
cannot be added to or deleted from the table either by the
agent or the management station while the application is
running. The agent will update service information table
objects as their values change when the application is
running. All objects in this table are read-only to the
management station. |
