11. The Abigail Braintree Foundation is a medium-size, not-for-profit literacy group that wants to implement centralized call processing. The group will implement a hub-and-spoke topology, with all of the remote branches utilizing Cisco Unified CallManager Express connected to the central site using Cisco Unified CallManager via an
IP WAN. The remote branch will be limited to 150 IP phones so the local gateway can provide SRST feature through Cisco CallManager Express. Each time a remote branch phone places a call, the control traffic traverses
the IP WAN (even if the call is local to the branch) to reach the Cisco Unified CallManager at the central site. All
the control traffic is exchanged between a Cisco Unified CallManager at the central site and endpoints or
gateways at the remote branches.
Which two signaling protocols can traverse the IP WAN in this deployment model? (Choose two.) A. SCCP
B. SCGP C. H.323
D. H.450.1
E. H.450.2
