Dialing with High Speed Data Cards
All models of HSU cards can place outgoing calls and can receive incoming calls.
All outgoing calls use call profile information to dial (see HSU Call Profile section earlier in
this chapter). A call profile is loaded into an HSU port’s dialing memory using the “D” (Dial)
option from the HSU Card Screen.
All incoming calls are routed to HSU ports based on the primary and hunt (optional) group
phone number(s) assigned to the HSU port. These numbers are assigned to each HSU port
using the Dial command option from the HSU Card Screen.
