Hey,
I want to share my newest project: FRITZ!Box Voicemail.
With this custom integration you can integrate your FritzBox voicemail/ TAM into home assistant.
The integration provides:
- Switch to toggle TAM
- Sensor to show messages count and messages (attributes)
- Media source to integrate audio messages into HA
You can install it via HACS with custom repositories (I already signed up for hacs default 
)
Repo Link with installtion guide in the readme: GitHub - mrtncode/ha-fritzbox-voicemail: Custom integration to integrate the fritzbox voicemail into Home Assistsnt. You can play messages, toggle the voicemail and view the current status · GitHub
I created a dashboard card too: GitHub - mrtncode/ha-fritzbox-call-card: Dashboard card for the home assistant Fritz!Box Call Monitor integration · GitHub
This card uses the FRITZ! Call Monitor core integration and my voicemail integration to show calls and playable voicemail messages!
I am happy about feedback and GitHub Issues
