DIOD Service


Direct Inward Outward Dialing (DIOD) allows companies to provide their employees with individual phone numbers for each person or workstation without a physical phone line present.

DIOD Enhanced

The enhanced service should be used when the 911 address of a DIOD is different than the service address. The 911 address will represent the address where the specific number is originating calls which is essential from a safety standpoint.
