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.
