where to find main line voicemail settings?

Hello @user_d5bc4a Thank you for reaching out over our Community forum page. Are you referring to Xfinity Mobile or residential Xfinity Voice service? 

@user_d5bc4a Gotcha! Thank you for verifying that for me. That does help narrow down things. The following link is to a document that will tell you how to do everything that you need for your Business Voice Edge phone number! https://business.comcast.com/support/article/voice/manage-your-business-voiceedge-voicemail-settings

That only tells me how to do things on my own phone. I'm looking for information on how to set up voicemail forwarding on our main line, which doesn't have a physical phone. For example, I have a hunt group set up during business hours for this line, but what happens after business hours? Where do the voicemails go and how do I retrieve them?
