[Freeswitch-users] Keep A Leg alive after bridge fails

Hello, I'm using outbound ESL socket to control calls and one of the actions is to bridge the A leg to another destination. This works great when the remote party answers, but when the remote party does not answer or is busy the bridge fails and disconnects the A leg. I wish to keep the A leg alive. I've tried setting different kinds of channel variables on the a leg and even the b leg, but without success. There is a thread from a few years ago discussing this very same issue (although they were talking about inbound socket), so I was wondering if anyone has a solution for this? Continue_on_fail, hangup_after_bridge, park_after_bridge, ignore_early_media, all don't work. Any ideas?
