Delayed Ringing

Allows outside lines ringing at a telephone to ring at another telephone or
group of telephones after a predetermined period of time.

Dialed Number Identification Service (DNIS)

ECS supports DNIS name and number on SIP trunks, T1, ISDN PRI and
ISDN BRI lines.

DNIS Alphanumeric ID

Based on programming, the DNIS (Dialed Number Identification Service)
alphanumeric ID is displayed on the station LCD when a call is received on a
DNIS trunk. A call can be routed to a station, master hunt group, or voice
mailbox according to the DNIS information received. DNIS numbers can be
assigned a 16-character alphanumeric ID through Iwatsu ECS programming or
by the service provider.
The information displayed on the station LCD during calls on DNIS lines may
be customized through database programming. During a call, you may change
the way the call information is displayed by pressing the [CID Display
Change] key. There are ten different display modes available to assign to the
[CID Display Change] key. You can scroll through each programmed display
mode choice each time you press the [CID Display Change] key.
Through programming, the number of calls permitted to simultaneously ring in
on a specific DNIS number can be limited and overflow to voice mail, another
extension or disconnected.

Direct Inward Dial (DID) Trunks

Iwatsu Enterprise-CS support DID numbers provided by your service provider.
This service, typically offered on PRI and SIP lines, allows any number of
telephones to be called directly from the outside without the need of having a
dedicated circuit for every telephone. DID numbers are available from your
SIP trunk, ISDN PRI/BRI or T1 service provider.
Through programming, the number of calls permitted to simultaneously ring in
on a specific DID number can be limited and overflow to voice mail, another
extension or disconnected.

DID Alphanumeric ID

DID (Direct Inward Dial) numbers may be assigned a 16-character
alphanumeric ID to identify the party being called, type of call, or purpose of
call.
