ISDN users

The ISDN user settings are configured by clicking on the button ISDN users.





Entry active
Activates or deactivates this entry.
Internal telephone number
Internal number of the ISDN telephone or name of the user (SIP URI).
Note: By using the # character as a placeholder, you can use a single entry to address entire groups of numbers, e.g. when using extension numbers at a point-to-point connection.
Note: User entries that use # characters to map user groups cannot be used for registration at an upstream PBX. This registration always demands a specific entry for the individual ISDN user.
Display name
Name for display on the telephone being called.
Comment
Comment on this entry.
MSN/DDI
Internal MSN that is used for this user on the internal ISDN bus.
  • MSN: Number of the telephone connection if it is a point-to-multipoint connection.
  • DDI (Direct Dialing in): Telephone extension number if the connection is configured as a point-to-point line.
Note: By using the # character as a placeholder, you can use a single entry to address entire groups of numbers, e.g. when using extension numbers at a point-to-point connection.
Note: User entries that use # characters to map user groups cannot be used for registration at an upstream PBX. This registration always demands a specific entry for the individual ISDN user.
ISDN/S0 bus
ISDN interface for the users to establish a connection.
En-bloc detection
With en-bloc dialing the device automatically detects that the dialed number is complete. A result of this is that the device places a call if it recognizes a group of digits as a contiguous block (e.g. for speed dialing). However, redialing is not an option.
Parallel call
If you use this feature, signaling occurs on all selected both ISDN lines. The call is accepted at the first telephone to pick up the call.
Domain/realm of PBX
Domain of an upstream SIP PBX when the ISDN user is to be logged in as a SIP user. The domain must be configured for a SIP PBX line in order for upstream login to be performed.
Authentication name
Name for authentication at any upstream SIP PBX when the user's domain is the same as the domain of a SIP PBX line.
Password
Password for authentication as a SIP user at any upstream SIP PBX when the user's domain is the same as the domain of a SIP PBX line. It is possible for ISDN users to log in to an upstream SIP PBX using a shared password (Standard password on the SIP PBX line).
Device type
Type of device connected.
Hide your telephone number from the person being called (CLIR)
Switches the transmission of the calling-line identifier on/off.
