Joining a Microsoft Teams meeting via a Zoom Room

Pexip Connect for Zoom Rooms enables Zoom Rooms and Zoom-registered Cisco/Poly systems* Zoom registered Cisco/Poly Room video devices require a Zoom Room Connector license to register to Zoom cloud. to make SIP based video calls into any Microsoft Teams meetings via Pexip’s interoperability service.

It provides Zoom users with a familiar SIP video experience when connecting into Teams from Zoom Rooms. The service supports dual screen video and content sharing.

Note that this is a guest join experience, therefore someone has to be in the Microsoft Teams meeting to admit you from the lobby.

* Zoom registered Cisco/Poly Room video devices require a Zoom Room Connector license to register to Zoom cloud.

Supported Room types

The following Room types are supported:

• Windows, Mac, and Android Appliance Zoom Rooms systems that run Zoom Rooms software version 6.3.5 or later.
• Cisco/Poly SIP rooms using Zoom One Button to Push.

Licensing requirements

Pexip Connect for Zoom Rooms has the following licensing requirements:

• Your Pexip Connect for Zoom Rooms license count (minimum 10) must match your Zoom Room plus Cisco/Poly Room count.
• You can also order an add-on package that provides Full HD (1080p) video and content (see Enabling Full HD (1080p)).

Note that:

• Pexip's CVI licensing is not required for Zoom interoperability (this is noted for clarity as Zoom uses "Pexip CVI" terminology in its admin interface to represent the Teams interop functionality via Pexip). However, we do recommend also purchasing CVI licensing to ensure that your internal Teams meetings are interop enabled for external guests and internal SIP endpoints that are not registered to Zoom.
• Pexip reserves the right to audit your Zoom Room count twice a year. Such an audit can consist of requesting a screenshot from the Zoom admin center showing license count.

• If somebody without a valid license plan tries to place a call they are shown a screen saying their call cannot be connected and they should contact their Zoom system administrator to validate their Pexip license.

  

Microsoft Teams/Exchange settings

The hosting Microsoft environment must be configured appropriately to allow interoperability with Zoom Rooms:

• To allow Zoom Rooms to join Teams meetings, the Teams tenant that is hosting the meeting must have enabled the "Anonymous users can join a meeting" setting (Teams Admin Center > Meetings > Meeting Settings) or alternatively set up a policy to bypass this restriction.
• To support One-Touch Join, the invitation must come from an Exchange server whose calendar processing settings for room resources have the DeleteComments property set to False.

Configuring Zoom for Pexip interoperability

You enable interop via the Zoom admin portal.

You will need to enter your Pexip customer ID: you must go to this registration page to request your customer ID after completing the Pexip Connect for Zoom license purchase.

For Zoom Rooms:

1. Go to Room Management > Zoom Rooms > Account Settings > Meeting.

2. Enable Support Interoperability for Zoom Rooms.

   You have to lock the settings if you want to ensure they are applied to all Zoom Rooms (and thus override any individual room settings).

   

3. Select Support joining Microsoft Teams meetings.
4. Select Support Microsoft Teams SIP (CVI) connectivity on Zoom Rooms.

5. Adjust the Preferred interoperability meeting connection method so that Use SIP or Pexip CVI to connect is the top priority.

   This reveals the remaining settings you need to configure.

6. Select Enable Pexip Cloud Video Interoperability (CVI) "SIP Guest Join".
7. Enter your Pexip customer ID.
8. You should also ensure that you comply with the Zoom Room firewall requirements.

For Cisco/Poly systems:

1. Go to Room Management > Cisco/Polycom Rooms and then Calendar Integration.
2. Enable Parse Microsoft Teams Meetings and enter your Pexip CVI customer ID.

Optimizing geographic routing for dial-out

By default Zoom Rooms exit the Zoom network in the US. If you want to change this (i.e. if you are not in the US), you can nominate which geographic region to use when dialing out via H.323 or SIP from your Zoom Rooms and user clients. This will typically reduce the latency as the call to the Pexip Service will stay in a region closer to the Zoom Room placing the call.

We recommend that customers in European countries should set Netherlands as your call-out location.

To do this, from within the Zoom portal you need to enable the Customize data center region for H.323/SIP call-out option, and then select the CRC Gateway you want to use.

The CRC Gateway can be set company-wide in account settings, or in the Zoom Rooms menu (via the In Meeting (Advanced) option) where it can be set in the room hierarchy or on an individual Zoom Room.

We recommend that you organize your Zoom Rooms in a hierarchy (e.g. by country, city, building as appropriate) so that you can the apply routing per country in a simple manner.

Enabling Full HD (1080p)

If you have the Full HD (1080p) add-on then there is additional configuration to ensure your Zoom Room or SIP/H.323 system can use Full HD:

1. Make a request to Zoom support to enable Full HD 1080p on your account.

2. Enable 1080p in the Zoom portal:

   1. For Zoom Rooms: in Account Settings > Meetings, set Meeting-HD Video Quality to Full HD (1080P)
   2. For Cisco/Poly systems: in Room Management > H.323/SIP Room Connector, set DTMF Command to 309.

Troubleshooting

This section contains some troubleshooting guidance.

Firewall/ports connectivity issues

The Zoom Room must be able to dial out via SIP. To test this, place a manual SIP call to a known good address, for example test@pexip.me:

1. Tap Home on the Zoom Room controller.
2. Tap the arrow to the right of New Meeting.
3. Tap Call SIP/H.323.
4. Enter test@pexip.me, tap SIP, then tap Call.

If this call fails to connect, check the Zoom Room firewall requirements, or contact Zoom to troubleshoot before continuing with the Pexip setup.

For Zoom SIP registered devices, it may be necessary to adjust firewall ports to allow RTP media over UDP to the destination IP addresses shown in Pexip's firewall rules guidance.

Pexip Connect for Zoom Rooms meeting experience

The following images illustrate how participants and presentation content are displayed on a single-screen and a dual-screen system.

We recommend the following display/layout configurations for Zoom Rooms with 2 displays:

Similarly for single screen displays, we do not recommend setting the 2 participants layout to Gallery View as this will show your own Zoom Room self view on half of the screen, and the remote feed from Pexip on the other half. The Pexip interop service detects it is a single screen endpoint, thus it will share any content as part of the layout mix, and therefore the endpoint will never enter the "share starts" setup.

Screen sharing settings — important for wireless sharing

Screen sharing settings can be changed globally, and some can be changed per Zoom Room — you need to decide the most appropriate method. We recommend the following settings:

• How many participants can share simultaneously: select One participant can share at a time.
• Who can share: select All Participants.
• Who can start sharing when someone else is sharing: select All Participants (if you are not able to take over presentation with, for example, wireless sharing).

During a meeting you can also access these settings (to apply to that meeting only) via the cog wheel on the Share Content panel.
