Weird Parked Calls issue


I have freepbx with Asterisk, and I am having a problem with parked called. When I go to park a call, if I wait for the system to tell me the line, the call parks fine but when I go to pick it up I get disconnected. If I don’t wait for it to tell me the parked extension, I can pick the call up fine. I have another freepbx running asterisk 1.4 and don’t have this problem. Any suggestions?
