Preferred exchange line | Expert
Defines via which exchange line outgoing external calls will be routed by a group member logged in as outgoing.
Automatic occupation
For outgoing external calls, any available connection is used, whereby first the fixed network connections and then the VoIP connection and at last the GSM connections were taken into account.
Special preferred exchange lines
For outgoing external calls, the connections released under Expert are used depending on the selected priority. This makes the definition of a preferred exchange line (priority = 1) with overflow to other connections (priority > 1) possible. Exchange lines with priority No automatic occupation are not used for outgoing calls.
As subscriber
The preferred exchange line of the subscriber is used.
* Note: If all released connections are busy, it is no longer possible to call. The subscriber can only use a connection with the setting No automatic occupation by entering a character string (see Targeted Exchange Line Access).
* Note: The same priority may be allocated to different external connections in parallel.
Number presentation (outgoing) | Expert
Defines which phone number is presented by a group member logged in as outgoing.
No
The phone number is suppressed.
Standard
Both the DDI parallel to the internal number and the MSN on the PTMP connection are displayed on the PTP connection over which the group is called (if the group is not a member of the call distribution for this connection, the first MSN is presented).
Exchange line dependent
The phone number to be presented is configured separately for each external connection under Expert.
* Note: On a connection with a GSM gateway, the phone number presentation configured in the PBX is not used because the actual phone number presentation is directly configured in the individual GSM gateway.
* Note: On a connection with CLIP no screening enabled, the number presentation defined here is not considered.
* Note: For the option No, the phone service Calling Line Identification Restriction (CLIR2) must be released by the network provider.
Number presentation (incoming) | Expert
Defines which phone number is presented back to the caller by a group member logged in as outgoing.
No
The phone number is suppressed.
Standard
Both the DDI parallel to the internal number and the MSN on the PTM connection over which the group is called are presented on the PTMP connection.
Exchange line dependent
The phone number to be presented is configured separately for each external connection under Expert.
* Note: For the option No, the phone service Connected Line Identification Restriction (COLR2) must be released by the network provider.
* Note: On a connection with a GSM gateway, the phone number presentation configured in the PBX is not used because the actual phone number presentation is directly configured in the individual GSM gateway.
