VOIP with HT801 will not work when assistnat response is set to nothing in automations.

[Code-Spinner1]

The problem

It seems that if you create an automation that does not allow the voice assistant to reply, ex: SetConversationResponseTo '', as the first argument, the conversation never ends over VOIP. When this happens, there is of course no "end conversation" chime, and it appears things are broken.

Perhaps instead of a voice response from the assistant triggering the end of an action, there could be a notification signal instead, allowing us to continue with automations where we don't need/want a response.

What version of Home Assistant Core has the issue?

2025.5.1 and probably since the VOIP integration with HT801 as implemented.
