Narrative:
We had a stuck microphone on frequency that lasted for about twenty minutes. We asked for a new frequency but they could not give us one; so we had to do what we could do to keep aircraft separated in our area. We came to find later that it was a B737 with the stuck microphone because that was the only airplane we had left. The problem was that the B737 was in conflict with another aircraft about twenty minutes away. I got control from the previous sector to climb early so we didn't have to watch it. We climbed her and then the stuck mike returned. It was twenty minutes later and the aircraft crossed paths 2;000 ft apart but we still didn't have another frequency. An alternate frequency should be available for emergency situations as this one. This is a very unsafe situation!
