Question :-

Ajax has decided to open regional sales offices to put their sales staff closer to their customers. The new offices are located in Oakland, Denver, Chicago, and New York. The Northwest and Southeast regional sales offices are located the Redmond and Atlanta facilities. The sales offices will connect to the Ajax campus via a Frame Relay network. Each site will have a PSTN gateway for local and emergency calls. All calls to and from the regional offices as well as long distance calls should use the IP WAN as much as possible. Call processing and voice mail will remain centralized Atlanta. H.323 gateways will be deployed at the remote sites for PSTN access. The Ajax central campus and regional sales offices will use the G.711 codec locally. The G.729 codec will be used when calls cross the WAN, and cRTP will be implemented on each link. The voice-mail system only supports G.711. The final phase of the conversion to Unified Communications will be the migration to a Cisco Unity solution. Priorto the migration, the existing Audix voice-mail system will be used. What design issues need to be considered so that all user can access theirvoice mail?
the selection of a codec that will provide excellent call quality and low bandwidth
transcoders at each branch location
specifying the correct number of inboundAudix ports in the Cisco Unified Communications Manager cluster
the dial plan needs to accommodate calls to the Cisco Unity system
transcoders atthe HO location
