3PIP Phone Interop with Microsoft Teams - Personal Feature Testing
Recently, a few questions came to me regarding 3PIP Phones interop with Microsoft Teams. Per Microsoft's Blog Post, the following features are available/working on 3PIP phones, but not everything is fully specified:
Authentication: All Skype for Business sign-in capabilities will remain unchanged.
Calling: Skype for Business users will be able to make and receive calls on their phones with no change to their current experience.
Presence and picture information: Presence information will work.
Corporate and local directories: Users will still have access to their corporate and local directories.
Joining Skype for Business scheduled meetings (Online or Server): All existing Skype for Business meeting capabilities will continue to work.
Additionally, the following IP phone features are expected to be supported when an IP Phone user is enabled for Teams:
Incoming/outgoing P2P calls (when calling a Teams-enabled Skype for Business phone user)
In-call controls via UI (mute, hold/resume, transfer, end call)
Phone notifications about upcoming meetings
Calendar access and meeting details
One-click join for prescheduled meetings
Mute/unmute for conferences
List of meeting participants
Hold/resume for conferences
Hang up from conference calls
Ability for IP phones to add another Skype for Business user to an ongoing meeting by using the Add Participant feature
Due to some questions regarding call queue functionality (As that is not defined by Microsoft as "Supported"), I decided to do some testing of my own, As of today, I can confirm the following on interop mode:
Calls from CQs in non-conference mode work, however it does not work when in the newer conference mode
Transfers to another Cloud AA Works via DID & SIP
Transfers to another Cloud CQ Works via DID & SIP
Meet Now Button is not working
VVX Phone Forwarding/Simul Ring Options don’t work unless set in Teams desktop client
DND/Presence Change is Not Working - Changes Presence, but goes back in a second
No MWI notifications - Must Call into Voicemail Service - Cloud VM limitation
One-Click Meeting Join Works
You can Join a Microsoft Teams Meeting from VVX with limited functionality as described above
Putting a Call on hold works for more than 30 seconds and you can re-answer the call
There is no personal Speed Dial or Contacts List
Note that some phone models have their own internal contacts list. This is able to be used, but must be manually set.
If a user is migrated to Teams from Skype for Business, they will retain their contacts list, but it will not receive anymore updates after the time of their move. (Thanks @JensHMadsen)
