CVP with CUSP Deployment

[Sivanesan Rathinam]

Hi All - In comprehensive call Flow i.e  CVP with CUSP Deployment, Once the agent has reserved VRU PG passed the label (Extn) to CVP which then passes to CUSP, Since i am using O/B Proxy Deploment in CVP.

CUSP will initiate O/B SIP INVITE to CUCM, In such Scenario will CVP maintain call control till end of the call to provide subsequent call control?

What happens if i shutdown (not Graceful shutdown) call server in OPS Console, call will terminate immediately?

The SIP proxy server provides dial plan resolution on behalf of SIP endpoints, allowing dial plan information

to be configured in a central place instead of statically on each SIP device. A SIP proxy server is not required

in a Unified CVP solution, but it is used in most solutions because of the benefits of centralized configuration

and maintenance. Multiple SIP proxy servers can be deployed in the network to provide load balancing,

redundancy, and regionalSIPcall routing services.

The Unified CVP SIP service is the service on the Unified CVP Call Server that handles all incoming and

outgoing SIP messaging and SIP routing. The Call Server can be configured to use a SIP proxy server for

outbound dial plan resolution. Cisco recommends that you use a SIP Proxy Server to minimize configuration overhead.

If someone stops the process with calls in progress. This situation occurs, when a system administrator

forgets to do a Call Server graceful shutdown. In this case the CVP Call Server will terminate all active

calls to release the licenses.

Please refer to HA Section of SRND for more details.

If you do not graceful shutdown all queued calls will drop, however calls already connected to an agent should remain active as the RTP stream is between the endpoints, might be worth testing.

HTH,
