4. 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 IPWAN in this deployment model? (Choose two.)
A. SCCP
B. SCGP
C. H.323
D. H.450.1
E. H.450.2
