Requirements
Planned Changes
Contoso plans to migrate all existing services from Skype for Business Server to Teams.
Direct Routing will be deployed for the existing SBCs.
Existing meeting rooms have Skype for Business Server video endpoints that are Skype for Business Server-certified. The endpoints are not Teams-certified.
You plan to use the video endpoints in Teams until the equipment is replaced with Microsoft Teams Rooms.
A limited pilot of the Teams migration and the Direct Routing deployment will occur in the Vancouver facility before deployment to the entire company.
Technical Requirements

During the limited pilot, the media path must be optimized.
Media flow for the remote sales team users must be optimized.
All sales team users require inbound toll-free audio conferencing.
Users in the Vancouver facility must be able to place emergency calls regardless of internet availability.
When users in the returns department dial out, the outbound calls must display Contoso and the department's phone number.
The video endpoints for the existing meeting rooms must be able to be used for both voice and video conferencing in Teams meetings.
