[Freeswitch-users] Dialplan comand bridge => Keep the first leg open if the callee was hang up the call

Hi, Call leg A is bridged to B <action application="bridge" data="sofia/gateway/mySipTrunk/B" /> B a pickup the call and hang up the call. A will hang up too, why? Is there a possibility, to keep the first leg open? I tried park_after_bridge=true, hangup_after_bridge=fals, park as dialplan application after the bridge, But nothing helps. Thanks a lot
