Internet telephony phone numbers

HiPath 3000 supports connection to the Internet telephony service provider (ITSP) and, there-
fore, the use of Internet telephony.
For Internet telephony subscriber lines, each call number must be individually registered at the
ITSP. Up to thirty ITSP client user account IDs can be configured. The ITSP client user IDs and
the Internet telephony phone numbers are supplied by the provider once an Internet telephony
subscriber line is requested.
An Internet telephony system connection with DID is a connection that supports DID and for
which an ITSP, an Internet telephony system phone number, an ITSP system ID (SIP system
account) and a call number range with Internet telephony phone numbers are provided. Up to
30 Internet telephony phone numbers may be configured in the system.
The system is configured for connection to an ITSP via Web-Based Management (WBM) and
Manager E.

Numbering in Networked Systems

In private networks, station phone numbers, seizure codes, and service codes are assigned
according to a numbering plan provided by the customer.
HiPath 3000 supports the following numbering schemes:
Closed numbering
Requires that all station numbers are unique within the network. Each station in the net-
work can reach another station by dialing their phone number.
Open numbering
This means that stations are identified using a node number (PABX number) and their sta-
tion number. Stations in different nodes (systems) may therefore share the same number.
M.164 numbering
The numbering can be open or closed. A node number is not required. The stations can
be reached via their public number, i.e., their E.164 number. Each station is represented
by its E.164 number which can be displayed optimally. The advantage of the E.164 num-
bering is that the station can be reached via a number and no node number is required.
The same numbering plan must be selected for all networked systems (nodes).
