Advanced Warm Transfer Not Working
# ❓・bug-report
l
The advanced warm transfer (warm transfer which can chat with human via the transfer agent) isn't working. This has been working fine since the feature went live but since the outbound calls stopped working about 6 hours, the advanced warm transfer is no longer working. Whilst outbound calling is back live, I wonder if there is still a problem with the agent transfering? It appears that the agent picks up but can't understand anything from the user? Please help and thanks in advance.

Call id for inbound receptionist: call_847f85bc0c96065b3450c5d30eb Call id for transfer agent attempt which failed: call_b95675cd363d2b96a73bf684 The user picked up the phone, said yes to accepting the transfer but it didn't work. In this case, the call timed out but on previous attempts with longer call timeout periods, it still hasn't worked when the user said yes to accepting the call?

Hello @Luke , can you turn the gobal node off for the birdge and try again ?
l
Okay, I will try that over the weekend as I'm in the UK and its the evening now. Thanks for your response
@Omar Ashraf | Community Lead It still isn't working. It's going to the bridge transfer node but isn't actually bridging the transfer. Please see screenshot. https://cdn.discordapp.com/attachments/1459185562350125228/1460203423289966614/image.png?ex=69660fe9&is=6964be69&hm=ede7be5c358e2d62e1497ec60377dc227f1ae75cddc32ba05062018bf793fd2d&
The transfer agent is also being really buggy and cutting out, long pauses etc.
