Distinctive Ringing
Users sometimes need to distinguish the ringing of one button on their phone from another
button and sometimes stations in close proximity to one another need to distinguish the
calls on one desk from another. Typically, multiple sounds are used to provide this distinc-
tion. Distinctive ringing can be assigned to each
Line
or DN button on each telephone.
You can set up to ten different incoming ringing tones for internal, as well as external
calls. Previously, distinctive ring was not provided for internal calls.
Do Not Disturb (DND)
Station users with IP telephones can activate DND to prevent any calls from ringing their
telephone. Callers will hear a fast busy tone when calling stations in the DND mode. Sta-
tions in DND mode can originate calls normally; however, they receive DND stutter dial
tone (optional) when originating calls.
Call Forward-Busy will forward calls directed to a telephone with DND set, even if the
telephone has idle DNs. Telephones with DND Override capability can ring DND tele-
phones.
Emergency Call
An Emergency Call access code can be established in the IP
edge
Net system to route calls
to specified emergency destinations and to prioritize their delivery to those destinations.
Up to four emergency destinations can be programmed for each mode of operation: Day,
Day2, and Night. This is particularly useful in applications where employees, patients, or
guests are not expected to know where to call for help at different times of the day.
Enhanced 911 (E911)
Enhanced 911 calling means the routing of a call to the appropriate Public Safety Answer-
ing Position (PSAP) accompanied by Caller Emergency Services Identifier (CESID). The
CESID identifies the location where emergency services are to be sent.
The IP
edge
system can use either SIP trunks or SIP PRI gateways - which requires carrier
and gateway support. Each 911 call generates an SMDR record at the beginning of the call
to enable the business to initiate its own emergency response. Internal emergency destina-
tions can also be automatically included in an emergency call. E911 calls can be routed
across an IP
edge
Net network for connection to the public network.
