With Exchange and Skype for Business Server 2019 now GA I decided to created a new lab environment, both are Hybrid installations and I opted to create a brand new Office 365 tenant.

For those not already aware Skype for Business Server 2019 (when paired with Exchange Server 2019), no longer has the ability to provide Unified Messaging and Microsoft expects customers to instead leverage Azure or “Cloud” Voicemail. There’s a great table (I’ve stolen from TechNet below) that illustrates supportability across the various versions.

Exchange Server 2013 Exchange Server 2016 Exchange Server 2019 Exchange Online
Skype for Business Server 2019 Exchange Server UM Exchange Server UM Cloud Voicemail Cloud Voicemail
Skype for Business Server 2015 Exchange Server UM Exchange Server UM Cloud Voicemail Exchange Online UM
Lync Server 2013 Exchange Server UM Exchange Server UM Cloud Voicemail Exchange Online UM

The planning and setup is well documented here and I followed this guide without any issues, however when I placed a call to voicemail I was seeing call failures, specifically:

“Failed to route to Exchange Unified Messaging Server”;source=”FE.DOMAIN.COM”



The first thing I checked was the licensing, now Microsoft’s requirement is that at least a single user is licensed for Skype for Business with a Teams license assigned. This new tenant met all the prerequisites, but still voicemail would not route correctly and was being rejected by Office 365.

Next step, I logged a ticket with Microsoft. It turned out that the issue was due to the fact that because no calls had been made between any cloud homed users voicemail had not yet provisioned itself correctly. As a workaround I was asked t0 log into two Teams users within the tenant in question and place calls in both directs. Voila – Cloud Voicemail immediately started working!

I was given the impression by Microsoft support that this is a temporary issue and will be addressed in the near future, in the meantime I’m sharing this workaround with other folks.

Just a brief update, I was asked to put together a RealConnect for Microsoft Teams provisioning walk-thru. This includes some recent updates to the Polycom provisioning Web App.

The dulcet screaming from youngsters, toddlers running up and down my airplane’s aisles and folks donning their Mickey-branded attire can only mean one thing – I’m Microsoft Ignite bound.

This is the Microsoft IT Pro event of the year and a big deal for my Polycom/Plantronics colleagues.

This year I’ve been closely involved in building the next cloud iteration of RealConnect, specifically geared toward bringing a standards-based video room system or VTC into a Microsoft Teams meeting. Today the only room systems compatible with Microsoft Teams are exclusively Skype Room System v2 based – and this isn’t likely to change any time soon. Making this new service, RealConnect for Teams, extremely relevant for customers that don’t have Skype Room Systems in situ and can’t rip and replace their existing estate of VTCs.

For the past few months a number of large enterprises have been in beta and as of today this new Azure-based multi-tenanted solution is live and orderable!

Polycom has proven track record in providing Microsoft video interop solutions since, OCS, Lync, Skype for Business and now Teams, in fact they created the category for scheduled Microsoft video interop technology – I’m on of the patent holders 😉

Also Polycom is the only CVI service provider with a Microsoft supported interop solution for Skype for Business Online.

We learnt a lot of valuable lessons since we launched RealConnect for O365 (the cloud RealConnect Service for Skype for Business Online users).

  • Customers prefer concurrency-based licensing
    • Integration with Office 365 Admin Portal is no longer a requirement and replaced with PowerShell
  • Cloud Solution Provider (CSP) integration is optional for RealConnect for Teams (only required for RealConnect for O365)
    • Single license SKU for both Teams and SfBO (concurrent licenses shared across tenant)
  • Completely re-architected and purpose-built MCU infrastructure – designed for Teams and Azure multi-tenancy
  • First-party scheduling and support for Office 2013 or greater, Teams mobile etc.

With this service now live, Microsoft added some new PowerShell cmd-lets.

New-CsVideoInteropServiceProvider and CsTeamsVideoInteropServicePolicy

CsVideoInteropServiceProvider is used to define your provider, there will be additional providers (Pexip and Blue Jeans) so customers have the ability to create up to three providers. All of which can be active within a single tenant.

Users can then be granted via the CsTeamsVideoInteropServicePolicy with a video interop service policy, each user can have a single provider allocated. Once these are defined a user’s Teams meeting invitation will contain additional VTC co-ordinates (see below)

So let’s run through an example setup.

Step 1. Define video interop service provider. Note, items in bold are tenant-specific and issued when a tenant is provisioned

New-CsVideoInteropServiceProvider -Identity Polycom -AadApplicationIds a39192d4-7b9b-4c07-87d7-cbcd3fd97af7 -TenantKey “” -InstructionUri{ConfId}

Step 2a. Enable CVI for a user. is an example user account

Grant-CsTeamsVideoInteropServicePolicy -PolicyName PolycomServiceProviderEnabled -Identity

Step 2b. Enable CVI for your entire tenant

Grant-CsTeamsVideoInteropServicePolicy -PolicyName PolycomServiceProviderEnabled

Step 3. (optional) Enable lobby bypass for VTCs

Set-CsVideoInteropServiceProvider -Identity Polycom -AllowAppGuestJoinsAsAuthenticated $true

Within 8 hours of policy assignment the users Teams invite will then have the new co-ordinates. That’s it!

It’s no secret that existing IP Phones have been granted an upgrade path to Microsoft Teams and I’m not talking about Android-based IP Phones (which have a native upgrade story), refer to a video I took back at Enterprise Connect of Polycom’s Trio 8800 running the native Teams IP Phone experience

3PIP interop was originally announced via a blog post from Thomas Binder and has since been updated multiple times, the key information that can be gleamed here is that a 3PIP phone registered to a Teams-enabled SfBO account will be capable of:

  • 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

In this post I want to look at “One-click join for prescheduled meetings”. Firstly note prescheduled meetings, this is not “Meet Now” and it’s also only possible at the moment by leveraging the Outlook Microsoft Teams scheduling add-in.

So in my test I created a Teams meeting invite via Outlook and sent this to a user that was signed into a Polycom Trio (in this case the Trio was running in Skype for Business mode). Both users were running in “Islands” mode, more on these coexistence modes can be read here

Sure enough within the Trio calendar there was a “join” button, but how?

Let’s look at the invite, I decided to open the calendar invite and save the meeting as an HTML file. I then opened the file within my browser


There we see a Conference Uri, the “OnlineMeetingConfLink”, this URL clearly re-directs the endpoint to a Teams-specific meeting gateway which then allows the Trio to join the meeting (audio only)

Very cool!

Just a quick post, I’m currently camped out at Microsoft and we’re executing the RealConnect on-premises certification for Skype for Business Server 2015. I had to rack my brains when I was asked about how we could:

  1. Remove a single VTC from a meeting via a Skype for Business client (without ejecting others)
  2. As an organizer end the meeting for all participants both Skype for Business users and VTCs

This can be enabled on the RealPresence Collaboration Server via a system flag and is the same flag used to enable the roster for individual VTC participants, specifically:


This flag value can be specified as:

  1. ENABLE_CONSIDER_ORGANIZER  – enables VTCs within Skype for Business roster, conference organizers can disconnect individual VTCs and “ending the meeting” will result in both Skype for Business and VTCs being disconnected
  2. ENABLE_IGNORE_ORGANIZER  – enables VTCs within Skype for Business roster, conference organizers cannot disconnect individual VTCs and “ending the meeting” will not result VTCs being disconnected
  3. DISABLED – disables VTCs from being displayed within the roster (only cascaded link is shown)
  4. <BLANK> this will result in the same behavior as ENABLE_CONSIDER_ORGANIZER

It’s also documented that VTCs can also be prefixed to help identify them versus Skype for Business participants by updating the system flag POLYCOM_EPS_DISPLAY_NAME_PREFIX_IN_LYNC_ROSTER, I usually set this value to “VTC/” (without the quotes)
