Which SIP trunk deployment model is shown in this enterprise VoIP topology?
A. mixed TDM and VoIP
B. centralized
C. hybrid
D. traditional TDM
E. distributed
Answer: C
Explanation:
Hybrid SIP Trunk Model In a hybrid SIP trunk deployment, some of the businesses' sites conform to a
distributed SIP
trunk deployment model. In this model each site has direct SIP session connectivity to the IP PSTN,
and other sites
conform to a centralized SIP trunk deployment, accessing the IP PSTN through a central hub, which
has SIP session
connectivity to the IP PSTN (Figure 3). The hybrid SIP trunk deployment model may have multiple
"central" hubs in
different geographic regions, or for specific business functions, such as call centers.
