The squad will be shortened ahead of assembling on November 9.
Speaking at today's press conference in FAI HQ, Ireland manager O'Neill said: "After finishing third in a difficult qualifying group, we enter into the Play-Offs against a very good team in Bosnia & Herzegovina. Our fate is in our own hands and we will be doing all that we can to qualify for next summer's finals.
"We will play the second leg at the Aviva Stadium and that is a big plus for us because the Irish supporters were fantastic in our last game there against Germany and we know that there will be a similar atmosphere for this Play-Off."
Premium Level tickets for the second leg game between Republic of Ireland and Bosnia & Herzegovina at Aviva Stadium on Monday, November 16 are still available through Ticketmaster.ie, while more General Admission tickets will be released on Monday, November 2 through Ticketmaster.ie at 11am
