I'm introduce Direct Routing between Teams, Cisco and a service provider, as a manage migration, with a final solution of dropping Cisco. The current setup through Cisco, has QoS, voice VLAN, and once Direct Routing is installed, and E5 license applied to each MS account, around 95% of users will be migrated to Teams soft client, leaving a number of handsets still required for reception phones etc. Question, is it worth have a separate VLAN for voice anymore? Does Direct Routing provide The handsets with DHCP? How will call Admission work, is the provide from both ends? What ports are needed and are they different from Teams soft client? Does anyone have a High Level Design doc for handset migration? Thanks
