5.1.8 Using a specific line (Signaling of the respective number)

You can specify which line should be used for outgoing calls. For example, if you have two different numbers (e.g. your internal number and a group number) and signal these over different lines, then by selection of a line you can decide the number to be signaled for each call.

In doing so you can:

select a line for the next call only (5.1.8.1 Selecting a specific line for one call).

define a standard line, over which all outgoing calls should be made unless you have explicitly selected another line. See also 5.1.8.2 Defining a Default Line for Outgoing Calls.
