QSIG-MD Private Network Services
MD Evolution – Dialog 4422 IP Office 126
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 as local calls 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
transmission 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:
61
#
z
Dial the suffix “7”, which usually grants access to the Non-IP
hand-over service.
Your call on the IP network is switched over to the non-IP network
immediately, without interrupting your call.
Note: This service is only available 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.
