Microsoft Teams SIP Gateway, has been enabled for selected SIP phone models from Cisco, Poly, Yealink and AudioCodes to register with Microsoft Teams. Microsoft has made it east for customers to provision legacy handsets via the portal, and providing the ability to manage the devices via the MS Teams Admin Portal. It was great to test this with Telstra Calling for Office 365 on a legacy TIPT / Polycom VVX600 Handset running the latest firmware.
Migrating to Microsoft Teams Calling is getting more seamless every day, and now with the SIP gateway it allows you to migrate while still leveraging your investment in legacy devices while you migrate to Microsoft Teams Calling.
