MD Evolution – Dialog 4425 IP Vision
Networked third party call forward – Activation and cancellation
Services Reserved for Attendants
Operations on private calls – all types
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
perspective, private calls between nodes may be processed
like external calls, or considered as local calls to a node.
Certain services are only available on a network basis
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.
