If you're not sure if the other person's organization has open federation, contact them first by phone or email to ask.If the organization has open federation, you can add users in that organization to your Skype for Business Contacts list by adding their Skype for Business address to your contacts list.You will know when the transition is complete when your Avaya or Cisco telephone no longer has dial tone.When you are enabled, you will receive a welcome email from "Microsoft Outlook" with your temporary voicemail PIN.Skype for Business is not designed to be used with shared accounts for the purpose of instant messaging and presence.
You will, however, need to unlock your computer to see a caller’s ID before answering calls.
Skype-enabled desk-style phones will still ring when the connected computer is asleep.
You have four options to retrieve voicemail: 1) Listen to the audio email attachment that is automatically sent to your email account in Outlook, 2) Call the Outlook Voice Access number (785-864-1900), 3) From the “Phone” tab on the Skype for Business/Lync interface, and 4) Use the Skype for Business mobile app.
To set your secondary ringer to ring your computer’s internal/external speakers, see instructions for PC or Mac. Your computer must be awake to hear notifications/ringer for incoming calls.
If you want to hear notifications/rings and answer incoming calls when your computer is asleep or off, you'll need to set up simultaneous ring to ring another phone, such as your cell phone, or set call forwarding to send the call to another phone.
