Question 4

A company deploys centralized Cisco UCM architecture for a hub location and two remote sites. The company has only one ITSP connection at the hub location, and ITSP supports only G.711 calls. Remote site A has a 1-Gbps fiber connection to the hub location and calls to and from remote site A use G.711 codec. Remote site B has a 1-T1 connection to the hub location and calls to and from remote site B use G.729 codec.
