The Northwest and Southeast regional sales offices are located the Redmond and Atlanta facilities. The sales offices Aiotestking.com
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.
