> Attended transfer not swapping channel
> --------------------------------------
>
> 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: Asterisk Team
>
> 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
