[Freeswitch-users] Playing a phrase before bridge with variable expansion

Hi I want to play a phrase on aleg before bridge using this xml chunk <action application="set" data="bridge_pre_execute_aleg_app=playback"/> <action application="set" data="bridge_pre_execute_aleg_ data=phrase:queue_agent:*${cc_agent}*"/> but because cc_agent is expanded before it is set, the phrase input is always empty when bridging. is there anyway to have it expanded just before bridge?
