Full set: 60 questions

Answer options

A: point to CUSP ig address Correct answer

B: point to CVP ip address Correct answer

C: point to IOS q/ws loopback address

D: point to PG ip address

E: point to AW/HDS/DDS ip address

Correct Answer:

A. point to CUSP ig address; B. point to CVP ip address

Explanation

In a Cisco Unified Customer Voice Portal (CVP) SIP comprehensive call flow, the ingress voice gateway receives the incoming PSTN call and must route the SIP INVITE to the CVP Call Server for IVR treatment and routing. To accomplish this, the dial peers on the ingress gateway configured with the customer's dialed number (DNIS) are pointed either directly to the CVP Call Server IP address or to a Cisco Unified SIP Proxy (CUSP) IP address. The CUSP then acts as a SIP routing engine to load-balance and forward the call to the appropriate CVP nodes.

Why Incorrect

C. The IOS loopback address is typically used for local gateway identification, management, or survivability, not as the SIP next-hop destination for the dialed number.
D. The Peripheral Gateway (PG) handles CTI and GED-125 data signaling with CVP, not SIP voice bearer traffic from the ingress gateway.
E. The AW/HDS/DDS is a database and administration server; it does not process SIP call signaling or voice traffic.
