How External Line Transfer Works
External Line Transfer (System Telephone)
A suitably authorised telephone, for example, the telephone exchange, can transfer the
exchange line access required for an outgoing call to another internal telephone for a short
period of time. This is useful, for example, when this telephone is located in a publicly acces-
sible room, and is only occasionally used for external calls by an employee.
How External Line Transfer Works
External line transfer works like this:
• The requesting telephone must initiate an internal call with the telephone authorised to
make the exchange to request exchange line access.
Important:
For an exchange line transfer, the telephone making the transfer needs the
authority level itself to transfer external calls externally.
The requesting telephone needs at least the official exchange line
permission level for incoming external calls.
• After the function key assigned to exchange line transfer has been pressed on the
telephone authorised for making exchanges, a confirmation tone is issued to both internal
subscribers and the internal call must be ended.
• The requesting telephone now has access to the exchange line settings configured for this
purpose on the PBX. These exchange line settings apply until the first successful outgoing
external call or until the time limitation has elapsed for initiating the external call.
Note: The external line transfer function is configured in the PBX.
Configuring and Operating a Function Key for Exchange Line Transfer
Press the key during an internal call to transfer the external line access to your call partner for
a single external call. Afterwards, a confirmation tone is played on both internal telephones and
the internal call must be ended.
