Wake-up call and alarm not working

[Dirksteral]

Describe the bug I tried to set-up a wake-up call and alarm, but I get constant errors when I trigger either of them in the Apple Home app. Protocol in Homebridge shows error (see below).

Note:

• On FritzBox (version 7590; Fritz OS 7.29) I created a dedicated user with all rights; I enabled call monitor
• FritzBox is in use as VoIP-system
• Non-call-related actions such as switching on/off 5ghz wifi work perfectly fine trough homebridge/Apple Home.

To Reproduce Steps to reproduce the behavior:

1. Go to Home App
2. Click on FritzBox alarm or wake-up tile
3. Error shows in Homebridge protocol, desired action not executed

Expected behavior FritzBox should trigger alarm call to the phone number I put in fritz-platform -> extras -> alarm FritzBox should trigger wake-up call to internal phone number I put in fritz-platform -> extras -> wake-up

I would be grateful for any ideas on how to solve this! Thank you!

If someone should have the some problem: In the Fritz!Box Settings „Wählhilfe“ (dialer support) has to be activated in order for these features to work.
