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:

FRI 20-APR 15:28
L1 SMITH Peter-405		01:33
HAND OVER	MSG+DISC FLASH	>

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.
