This usually isn’t caused by the landline but by how the transfer type and audio settings are set up. Assistant-based transfers keep the hold music but don’t trigger the cancel event, while normal or warm transfers allow fallback but lose the audio. The workaround is to control how the assistant listens during the transfer and add a custom audio layer. Would you like the call to pick up where the assistant left off, or restart a new flow when it comes back? @Harrison5668
