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 i 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. In what locations will DSP resources need to be configured to minimize WAN traffic and support conferencing and transcoding?
The only location that will need DSP resources is the central campus.
DSP resources will only be required at the regional sales offices to convert G.711 to G.729 for WAN access.
DSP resources will be required at the central site to support transcoding for the voice-mail system, and at all site to support conferencing.
DSP resources will be required at the central site to support conferencing, and at the remote sites to supporttranscoding for the voice-mail system.
