Hey, do you have voicemail detection on? I used the assistant settings to configure voicemail instead of the voicemail tool for my outbound campaigns. And it worked reasonably well. Also, this can easily be glossed over but if you're using a tool for vm, make sure that you've equipped your agent with the said tool within the tools section in assistant's settings (this could've been changed in the new ui). And of course proper prompting is a must.
