While native Microsoft Teams phone devices provide the richest and most complete Teams experience, there are still many organizations with existing investments in legacy devices. To help these organizations leverage their existing legacy telephony hardware as they move to Teams Calling, Microsoft has launched the Teams SIP Gateway, a free cloud service that enables core Teams calling functionality on compatible SIP phone models from Cisco, Poly, Yealink and AudioCodes. This blog article describes the pre-requisites and steps on how to provision SIP phones for Teams calling using this new SIP Gateway. For detailed info, refer to the official MS Docs site.

This article describes the process to re-purpose Poly CCX 400/500 from Zoom phones to Teams phones. Poly CCX 400/500 phones are flexible and can be used as generic SIP phones, Zoom phones or native Teams phones. For organizations that are using these phones as Zoom devices and are intending to migrate to Teams phones, there is no need to buy new phones. Simply re-purpose the phones following the the steps in this article

Microsoft Teams Rooms (MTR) on Windows platform solutions are by far the most deployed Microsoft meeting room solutions today and there are many vendors to choose from such as the Poly MTR on Windows kits. The solution comprises key components such as a Windows PC running Windows 10 with the Teams Room application, a Touchscreen control panel as well as a number of Peripheral devices (camera, microphone, speaker). Many organization have policies that require Windows PCs to join the AD Domain and have Group Policy Objects (GPOs) assigned to improve the security of the device. This blogpost aims to assist administrators on what GPOs may safely be applied to an MTRoW device without losing any functionality and what GPOs will render the device unusable. It is a continuation of the previous blog post.

Microsoft Teams Room on Android devices have been growing rapidly since its debut by Poly with the Studio X30/X50. While its relatively simple to deploy these devices, there are several considerations to ensure the devices can sign-in to the tenant especially when there are AzureAD and MEM/Intune security restrictions. This blogpost discusses in detail some of these considerations and how to identify and resolve possible issues.

In a previous blogpost, a brief discussion on how to configure a static web proxy on MS Teams Room on Windows (MTRoW) devices was provided, However many organizations require the use of Web Proxy Automatic Configuration (PAC) files to determine which web proxy to use depending on what websites are requested. In this post, we walk through step-by-step on how to configure Web Proxy PAC on an MTRoW device. Note that Microsoft strongly recommends that Teams media traffic should bypass web proxies as stated in this official doc as it may impact the network performance for real-time media. Nonetheless, organizations that require the use of Web Proxy for MTRoW devices may do so for normal web traffic. However, its important to note that MTRoW does not support web proxy authentication.

Microsoft Teams Cloud Video Interop (CVI) service is a Microsoft Qualified third-party solution that allows standards-based third-party meeting rooms (telepresence) and personal video devices (VTCs) to join Microsoft Teams meetings. Many organizations have already invested in legacy video teleconferencing devices which they may want to continue using. Cloud Video Interop provides a cloud-based solution with little or no on-premise infrastructure that allows these existing solutions to participate in Teams meetings. This blogpost walks through step-by-step the configuration of Poly's RealConnect CVI service for Teams. Full details on how to configure CVI can be found in this MSDocs webpage.

Formerly known as "Collaboration Bars", Microsoft Teams Room on Android (MTRoA) devices have become widely adopted in both large and small organizations that want a native Teams room experience in their small to medium sized meeting rooms. These devices are simple to setup and manage, and provide a rich Teams meeting experience thanks to many new features introduced since these devices began shipping last year. this blogpost focuses on some of the best practices deploying and managing MTRoA specifically on the Poly Studio X30/50 devices available today. 

In a previous blogpost the ability to join Webex meetings directly from Microsoft Teams Room for Windows was discussed. Since then, Microsoft has released version 4.6.20 which includes direct guest for Zoom Meetings (Preview) as well. In this post we take a look at the experience of joining Zoom meetings directly from Teams Room for Windows (MTR). While this is currently in preview, the actual release should be coming in the months ahead. With the ability to join both Webex and Zoom meetings directly from an MTR system, the need for USB pass-thru BYOD feature is significantly reduced as Teams, Zoom and Webex form the vast majority of online meetings conducted in the world today.

As many organizations around the world are adopting Microsoft Teams as their enterprise communication and collaboration platform, the demand of IP desktop phones continues to be strong as companies replace their aging PBX phones in place of newer Teams certified IP Phones. Teams calling plans are now available in more countries and Direct Routing can be used virtually anywhere with a certified SBC. To ensure the best possible call quality when deploying Teams Phone system, QoS can be implemented so that the network is optimized for audio and/or video calling. Microsoft provides detailed documentation on how to implement QoS in teams and in this blogpost, we look at how it works with Teams certified IP Phones such as the Poly CCX family shown on the left. Click here for the complete list of devices.

In the July update for Microsoft Teams Room version 4.5.35.0, a new feature known as Direct Guest Join was released that allows MTR devices to join Cisco Webex meetings directly without any gateway or cloud interop service. This feature expands the capabilities of Teams Room Devices and allows interoperability with Cisco Webex meetings with one-click join functionality. In this blog post we explore the required steps to enable Direct Guest Join on MTR and the overall meeting experience and current limitations. In the future, we can expect MTR to support additional meeting ecosystems in the same way as well. Direct Guest Join leverages WebRTC technologies to allow MTR to join meetings hosted in CIsco Webex and other future meeting platforms.

In a previous blog bost various tips on deploying and managing Microsoft Teams Room (MTR) systems was discussed. One of the tips was how to manually update the Teams Room app running on the MTR. In this post, we dive deep and walk through the actual steps involved in updating the MTR system. As of this writing the latest Teams Room App version is 4.4.25.0 and readers may refer to the MTR Release Notes website to get the list of versions available. In this walkthrough we are following the manual update steps as stated in the official MTR Operations documentation for managing MTR systems, along with some potential issues to look out for while performing the process. My MTR system before starting the upgrade was running at version 4.3.42.0

In a previous blog post we walked through the steps to configure our Teams environment with Direct Routing for PSTN calling. In this blog post, we build on the same setup and enable Location Based Routing (LBR). Note that LBR for Teams Direct Routing is a preview or early release feature at the time of this writing as stated in the official Microsoft documentation. For readers unfamiliar with LBR, this capability allows admins to prevent PSTN Toll-Bypass which is against regulatory requirements in certain countries. By configuring LBR, we can restrict toll bypass based on policy and the user's geographic location at the time of an inbound or outbound PSTN call. We can then verify that the LBR policies will also apply to certified Teams IP Phones such as the Poly CCX Family of Teams phones.

Microsoft Teams is fast becoming the #1 collaboration platform in the enterprise. In particular the voice workload has been steadily gaining momentum as more companies move to Teams voice. There are now many choices of certified Teams IP Handsets in the market which is helping to drive adoption even more. As large organizations deploy thousands of these devices in their network, there is a need for centralized management and provisioning so IT admins can make sure these devices are working smoothly. Fortunately, Microsoft provides the Teams admin portal which has a section dedicated to managing these Teams IP Phones. In this blog post we'll walk through the various management capabilities of this portal in managing certified Teams phone devices such as the Poly CCX family of Teams phones.

​Microsoft Teams Rooms (MTR) is solution that transforms meeting spaces ranging from small huddle areas to large conference rooms with a rich, collaborative Teams experience that's simple to use, deploy, and manage. This is because the MTR provides a native Teams experience by running a specific Teams Room App on a Windows10 compute device. MTR has been steadily gaining momentum over the last 12-18 months as users enjoy the ability to start meetings on time with one-touch join, then instantly project to the display in the room and share to remote participants. As of this writing, MTR systems along with the necessary peripherals such as cameras and speaker/mics are available from Yealink, Logitech, Crestron, Poly, Lenovo, and HP. In this article we explore the various tips and best practices to get MTR running quickly and smoothly and look at the various ways to manage the system.

Whilst the industry momentum is going towards adopting Microsoft Teams as the successor to Skype for Business, there will still be organizations that have yet to fully migrate to Teams and may continue to use Skype for Business for the interim term, particularly for companies that have invested in and leveraging Microsoft Phone System with SFB Online and hybrid voice. Whether its using CCE or Skype On-Prem Cloud Hybrid, their users are able to make PSTN calls via a local SBC with the associated SIP Trunk or E1/T1 lines. For these environments, it is desirable to retain PSTN calling in the event that the WAN connection to Office365 becomes unavailable. In this blog post, we walk through the steps on how to configure a Ribbon SBC1000 for PSTN failover such that if the WAN connection to O365 is disrupted, Skype certified IP Phones will lose connectivity to SFB Online but yet still be able to make PSTN calls via a secondary SIP connection to the SBC

In the previous blog post a Ribbon SBC1000 was configured for Teams Direct Routing using SIP Trunk from Masergy and tests calls made using the new Poly CCX Native Teams phones. That setup was configured with the default non media-bypass where media always flowed between the SBC and Microsoft Office365 Teams media processors or relays. As a follow up to that, this blog posts walks through the configuration of media bypass in the same lab setup, allowing media to flow directly between the Teams phones and the SBC, thereby simplifying the media flow allowing for potentially better call quality. Since it is fairly straightforward to configure media bypass, this post also provides wireshark packet capture on the SBC to show the media flow between non media-bypass and media-bypass calls

In a previous blog post a technical deep dive on deploying enterprise voice on Microsoft Teams was provided. In this post, we supplement and complete the discussion holistically by providing configuration guidance of a certified Session Border Controller (SBC) for Direct Routing. In this lab, we leverage the same tenant with Office365 E5 licenses and deploy a Ribbon (formerly Sonus) SBC1000 along with a PSTN SIP Trunk from Masergy including DID numbers. Detailed configuration screen shots of the SBC will be provided along with explanatory notes. Special thanks to DMUnified for assistance with the SBC!

In the previous blog post, we covered the details of deploying 802.1x EAP-TLS on Polycom VVX phones using Cisco 2960X switch and Windows NPS RADIUS server. Deploying device certificates manually on the phones can be a time consuming process especially for high security environments when a unique device certificate is required for each phone. With the release of UCS5.9.3 firmware in June this year, Polycom VVX phones now support Simple Certificate Enrollment Protocol SCEP for easy requesting and assigning devices certificates for 802.1x EAP-TLS authentication. This blog post builds upon the same lab environment of the previous post but describes in detail how to add and deploy SCEP.
