For a multi-login group only one call forwarding setting (call redirection)
can be configured. This applies to all telephones and can be set from any
telephone.
To use multi-login, multiple telephones can be set to have the same internal
telephone number.
4.4 Calling Line Identification Restriction (CLIR)
The CLIR function prevents the transmission of information about the calling
party. This is usually activated directly at the terminal equipment, i. e. in the
SIP phone or softphone, the subscribing user sets whether or not the calling
number is to be displayed to the called party. Often, this behavior can be set
up to occur generally or on a call-by-call basis.
If you activate CLIR in the LANCOM Business-VoIP-Router directly in the user
settings for SIP, ISDN or analog users, the number will always be restricted,
whatever settings the user makes in the terminal equipment.
CLIR is configured in LANconfig under VoIP Call Manager Users SIP
users , ISDN users or Analog users :
In some cases it may be desirable for the caller ID to be retained even if it is
restricted in the telephone or in the user settings. For instance, this is the case
where a SIP provider requires the caller ID for billing purposes.
