Voice over IP crashes if the assist does not give a reply

[Bram-diederik]

The problem

I finally reproduced the issue behind. https://github.com/home-assistant/core/issues/128483 It was kinda hard because the config of asterisk required changes.

If the assist does not give a reply the voip integration crashes.

I tried to reproduce the issue with tracing on but all my automatons that might give a empty response always gave results.

What version of Home Assistant Core has the issue?

2025.4.2

What was the last working version of Home Assistant Core?

2024.9.1

What type of installation are you running?

Home Assistant OS

Integration causing the issue

voip

I am also finding this is true for me; it was working fine for quite awhile, but lately when trying to use VoIP, it causes my entire Home Assistant to freeze and I have to reboot it. I am using a 3CX bridge connection instead of VoIP Gateway device or phone.

This could be related to this one as well https://github.com/home-assistant/core/issues/128372#issue-2586442538 It seems to have been broken for a very long time now. I have the same issue it crashes the core which reboots the server only after a while.

I've found that if I don't set a response with SetResponseOfConversationTo '', in my automations, it will work just fine. It seems the VOIP integration needs a response from Home Assistant before it closes that conversation.

I'm having the same problem using 3CX, but i noticed that home assistance voip plugin created 2 entities:

Device Info Entity no 1 - Model: 3CXPhoneSystem 20.0.6.724 (724) Entity no 2 - homeassistant 465632296274 2025.6.3

The moment i make a call, home assistance will freeze up and have to manual reboot

Kinda off topic for the fix. But i wrote a asterisk integration with a command line agent. https://github.com/Bram-diederik/homeassistant-asterisk-assist
