Solved "Resume failed" when trying to transfer active call to another extension

[Razva]

1. I'm calling somebody from 3CX
2. The person whom I'm calling answers
3. I'm successfully connected/talking
4. I want to transfer the call to another extension
5. I click "Transfer" and I select/double-click the extension where I want to transfer the call
6. The person whom I'm calling is hearing the background music (doesn't hears me any more)
7. My 3cx client briefly shows "Resume failed"
8. The extension whom I'm trying to transfer the call to is not notified in any way
9. I cannot continue the discussion with the person whom I'm calling (he's still hearing music)

Here's a full screen recording of the current situation: https://www.screencast.com/t/vZ93U1FXSRYi

Any hints on how to fix this?

Hello @Razva

Please make sure that under your Trunk settings / Options the options "Supports Re-Invite" and "Support Replaces" are not enabled.
Also make sure that the same options are enabled under your extension settings / Options.
