AT&T System 25 - Manual (Page 17)

Conference Calls
❑
You can set up a conference that includes a combination of
System 25 extensions as well as outside calls. You may have up
to five conferees; however, no more than two may be on outside
lines. To set up a conference, start with one call; then contact
the new parties one at a time and add them to the original loop.
You can drop parties before they are placed in a conference.
However, once in a conference, you cannot selectively drop any
party from the conference because they are all on the same loop.
If you want someone to withdraw from the conference, ask that
person to hang up.
