Please use the following information for local network setup for Microsoft Teams:
VLANs: Traditional deployments of phone systems sometimes place telephones on a separate voice-only VLAN for segmentation and Quality of Service. Microsoft Teams works very differently by combining audio, video, instant messaging, presence, conferencing, and screen sharing, then spreads these modalities between a computer running the Teams client and sometimes an IP phone. Given this, CallTower recommends that customers do not implement a separate VLAN for Teams traffic and instead place all Teams client machines (including phones) into the existing data VLAN. Direct access to the internet is the preferred configuration for Microsoft Teams.
Bring Your Own Broadband (BYOB): Quality of Service (QoS) is greatly impacted by: LAN and WAN bandwidth, jitter, latency, packet loss, poor Internet connection, an inadequate router, and the Customer’s network being improperly configured. Quality of Service (QoS) for the Customer’s remote users will also be impacted by the items listed above.
Please see the following documents for network access requirements for Microsoft Teams. These settings are required whether using a full client on a PC or using a Teams phone.
