Voice over IP (VoIP)

Internet telephony features are described in detail in the
>
Voice over IP (VoIP) enables voice data to be transmitted over an IP network, both internally
and via the Internet.
Voice over IP (VoIP) is an outstanding feature of HG 1500. In combination with the clients con-
nected to the LAN, the board makes it possible to use not only VoIP but also the telephony fea-
tures of the system. In particular, this feature can be used for teleworking. This means that full
Voice over IP functionality is available at the teleworking PC.
As of the HiPath 3000 V3.0 software version in combination with new boards (HXGS3, HXGM3,
HXGR3), login is no longer performed under "Voice Gateway" in HiPath 3000 Manager I but in
HiPath 3000 Manager E.
The following combinations of VoIP connections via the HG 1500 are possible:
IP to IP, for example, subscriber C to subscriber D or subscriber D to subscriber F.
●
IP to local SCN, for example, subscriber D to subscriber B.
●
Local SCN to IP, for example, subscriber B to subscriber C.
●
IP to PSTN, for example, subscriber C to subscriber E.
●
PSTN to IP, for example, subscriber E to subscriber D.
●
Interworking is fully supported.
With the exception of IP to IP connections, one DSP channel per connection is required for
each HG 1500 involved. Conferencing requires one DSP channel for each SCN subscriber.
In IP networking, SCN to SCN connections (local or PST) also can be run transpar-
>
ently via the HG 1500. This is described in Section 13.6.3, "IP Networking".
This can lead to significant call charge savings if an appropriate IP network is available. The
user can also avail of telephony features, such as name transmission and callback, in the usual
way.
