QSIG-MD Private Network Services
Notes:
The voice message services are available only if an integrated
voice mail system is available for each private network within
a company.
Within the framework of a company’s private network, the
attendants may be decentralised on each network node, or
centralised on a systems subset. From an attendant’s per-
spective, private calls between nodes may be processed
like external calls, or considered to be calls local to a node.
Certain services are only available to a network depending
on the specific rights assigned to your extension. This is
applicable for the following services: supervision of network
extension statuses, secret of identity for private calls, and
general calls acceptance for private calls.
Non-IP Hand-Over Service
If your telephone system is integrated within a QSIG-MD private
network, and your calls are routed over your company’s Intranet
network, which managed according to the IP-Trunking technique,
you may also have access to a non-IP hand-over service.
The quality of communications established over the Internet network
is generally good, mostly thanks to the implementation of a system
that gives voice calls priority over data transmitted on the IP network.
However, occasions may arise where the quality of the voice trans-
mission of calls over the IP network is reduced. The non-IP hand-
over service allows you to request that your current call be switched
to a possible private digital tie line, or the public network (depending
on availability).
To activate this service during an ongoing call established over your
company’s IP network:
HAND OVER Press the dynamic function key shown on the left.
Your call on the IP network is switched over to the non-IP network
immediately, without interrupting your call.
Note: The “HAND OVER” function is only available,
obviously, when your call has been established on the IP
network. The non-IP hand-over service is not available for
QSIG-MD private networks using an Intranet network
managed according to the IP-Networking technique.
