How does voicemail work?

The user has access to two voicemails: one from Telavox and one in Teams. Telavox recommends using the Telavox voicemail, as it offers the following benefits:

One voicemail for both fixed and mobile numbers
More flexible settings for when it should be used
Works even during Microsoft service outages
No risk of the voicemail answering incoming group calls (Teams voicemail can take queue calls from the user if it is not disabled, see row 11 below). The Teams voicemail can be disabled under Settings → Calls.”

Both direct and queue calls to my fixed number are redirected to my Teams voicemail when I don't answer or the client isn't running. This is due to the personal setting in Teams client. Under the "calls"-setting all users needs to set "If unanswered" to "Do nothing".  📞 Call handling
Teams have "call waiting" activated by default. The setting is called "Busy on busy" and you inactivate call waiting by activating the "Busy on busy"-setting in Teams. This is due to a calling policy in Teams portal called "Busy on busy". This should be activated by the Teams admin when setting up the solution. 📞 Call handling
