DISA (Call Through)
Call Throughto avoid high telephoning costs allows the use of LCR
and VoIP/GSM routing of the PBX even when phoning over e. g. a
smartphone. First, call the PBX and get connected to the desired
connection. Call Through allows the direct redial of any phone number.
The called person does not receive the mobile number but the company
number.
Requirements:
• The transmitted subscriber number must be registered as Call
Through subscriber
• The transmitted subscriber number must not be in the MSN blacklist
• Configured 6-digit Call Through PIN
Procedure:
• Dialling the predefined external number of the PBX for Call Through.
• The PBX accepts the call and signals this with a special tone.
• Enter the
6-digit PIN and * . The exchange line dial tone is heard.
• Based on the transmitted phone number and PIN, the PBX checks if
the caller is Call Through user.
• Dialling the desired phone number (internal or external with prefix).
• After checking (exception number table, and if necessary LCR table),
the connection is established.
Note: If possible, have the mobile phone operator enter the PBK
number as special number (higher cost savings).
