Narrative:

Aircraft X was on an IFR flight plan inbound to julle on the JULLE4 arrival level at 8000. Aircraft Y was VFR opposite direction; climbing to 7500. Traffic was issued to both planes from 13NM and 12NM apart. The planes were going to meet at the sector boundary. The next sector had already taken the hand off on aircraft X; but I didn't switch him due to traffic. When they were about 1 mile apart aircraft X reported aircraft Y on TCAS; he also said he was going to have an RA. I asked the pilot if he wanted a vector around the traffic; he answered affirmative. Between issuing traffic and aircraft X reporting aircraft Y on TCAS; I had started giving a position relief briefing to another controller. My instructor had plugged in overhead to listen. When aircraft X reported that he was going to have an RA; since the relieving controller did not do anything; my instructor unplugged him and plugged in with me again. When my OJT instructor plugged in; the relieving controller said that aircraft Y had reported the RA. Because of this mix up; time was spent questioning aircraft Y rather than vectoring aircraft X. Shortly after that; aircraft X reported that he was climbing in response to an RA. We advised the supervisor. Recommendation; I learned how to respond to a pilot reporting an RA. Also; we should have the ability to have three controllers plugged into the same position so that the relieving controller; the ojti; and the trainee can do a position relief briefing.
