9. 2. 3 SIP-RFC supported by MiVoice Office 400
RFC (Request for Comments) are chronologically numbered, freely accessible docu-
ments in which the quasi-standards developed are published on the internet.
A whole range of RFCs are supported for connecting MiVoice Office 400 communica-
tion servers to SIP providers on the one hand and SIP terminals to MiVoice Office 400
communication servers on the other. They can be found in Tab. 4, Seite 41.
9. 2. 4 Features in the private network
This Chapter describes the user-related features in a PISN.
Standardized operation and signalling
The way in which a feature is actuated on the terminal and its signalling are identical
whatever the network used (local, PISN or public network).
Scope of performance
The range of services in a PISN is determined by the following criteria:
• Local features of the system
• Type of networking (QSIG or virtual with DSS1)
• Offer available from the public network provider
9. 2. 4. 1 Networking with QSIG
The standardized QSIG protocol supports a wide range of basic and supplementary
services. The system supports the following services:
• Display call numbers (CLIP) and names (CNIP)
• Enquiry/Hold/Brokering
• Call transfer with/without prior notice
• Conference (variable, preconfigured)
• Call Forwarding Unconditional (CFU) and Call Forwarding on No Reply (CFNR)
• Deflect/reject call during ringing phase
• Do not disturb
•Recall
• Callback if busy
Under QSIG the activated feature is indicated on system phones with a display, e.g.
Conference.
