Status: Waiting for Feedback (was: Triage)
Robert, is this something new you're seeing with 16.10 or was it happening with earlier versions? If earlier versions, do you remember which version it started to appear?
There are multiple threads involved in this scenario and I'm thinking that events are being generated on one thread before the swap is completed on another.

> Key: ASTERISK-28922
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-28922
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Bridges/bridge_simple
> Affects Versions: 16.10.0
> Environment: ubunutu 18.04, docker, asterisk 16.10, pjsip
> Reporter: Robert Sutton
> Assignee: Robert Sutton
>
> occasionally an attended transfer results in the agents channel name appearing in the bridge instead of the callers.
> It appears that asterisk fails to swap the channel names.
> The connected parties are as expected but the channel names are wrong which is causing problems for reporting and some of our other external systems.
> I can't recreate this on demand, I would estimate the frequency at about 1 in 500 attended transfers.
> There are 4 channels in volved
> a (000005c6) caller
> b (000005d1) agent -> a
> c (000005cb) agent -> d
> d (000005d2) other
> The call flow is:
> 1 incoming call (a) answered by agent (b).
> 2 AMI originate a second call (c) to the agent.
> 3 agent answers second call (c) (the far end (d) is making progress, but not yet answered).
> 4 agent uses "swap" button on phone to talk to original caller (b).
> 5 agent transfers the caller to the other call (b,c) , simultaneously the other call (d) answers.
> 6 the bridge shows channels (d) and (b) in the bridge instead of (a) and (d)
> 7 the expected parties are bridged and call completes normally
