MWI

:
Message Waiting Indicator. An indicator that there is a voicemail message for the owner of an account.

RFC

:
Request for Comment. A document that describes an aspect of an internet technology. An RFC may be a proposed, draft or full internet standard.

MSN

:

Acronym for Multiple Subscriber Number.

MSN is a facility whereby you can have more than one telephone number allocated to one Isdn line.

Usually get up to 3 MSN numbers. Up to 10 MSN´s are possible on one Isdn line.



DID

:
Please see DDI

NAT

:
Acronym for Network Address Translation. This is a general term for the process of IP rewriting address information in communication between peers with private and public IP addresses.

:
Specific NAT strategy that is required to enable SIP telephony across private network boundaries.

UNC Path

:
Acronym for Universal Naming Convention. Provides a uniform syntax to describe the name of a network resource such as a file.

In Microsoft Windows, the syntax looks like \\host\share\path\file. host usually denotes the name of a network server. share denotes an entry point to the servers file system that has been made available to network users and path\file is the path to the resource blow that entry point.

For innovaphone boxes that have a WebDAV service (e.g. to provide access to the devices local CF card), you would use the devices ip address as host, drive as share and cf0\dir\file as path, e.g. \\172.16.0.10\drive\cf0\log\LOG0.0.txt.

ITSP

:
Acronym for Internet Telephony Service Provider. This is a voice carrier that offers termination of VoIP calls to the public telephony network via IP.

DSP

:
Acronym for Digital Signaling Processor.

The DSP is a piece of hardware which enables encoding, compression nd echo canceling of the media stream between VoIP and physical interfaces. Media encoding usually takes place on both ends of the VoIP media stream. DSP resources (so called DSP channels) are required on endpoints and gateways thus, not on a PBX.

No DSP channels are required when a call is placed from one physical interface to another physical interface when both reside on the same device (e.g. in a looped-in scenario) and the hardware supports it (as the IP800 and IP6000 do).

In fact, media encoding does not need to be done on a DSP. Contemporary standard CPUs can do this easily, thanks to their MMX extended instruction set. However, for low-cost, low-energy embedded devices, the DSP is the better choice.

For innovaphone devices, some DSP resources (e.g. on most of the gateways) require a per-channel license, some (e.g. on the phones and adapters) do not.
