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. |
