[Freeswitch-users] Method to force a transfer of A-Leg

Hello all, I have a lua script running that checks the state of a call between A and B - the call between A and B was set up through a Polycom's attended transfer feature, so A itself didn't necessarily execute the bridge to B. A gets early media from B. After a certain amount of time, if A is still getting early media, I want the script to end that call between A and B, and send A through some specific dialplan. How does uuid_transfer work for this goal? I'd like to kill B and move A to specific dialplan. I don't want B to be in the transfer at all. I know there may be many possibilities here; I'm just wondering if anyone can recommend something. Thanks. - Steve
