5.1.8 Use of a specific line
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.
