In a previous blogpost, a brief discussion on how to configure a static web proxy on MS Teams Room on Windows (MTRoW) devices was provided, However many organizations require the use of Web Proxy Automatic Configuration (PAC) files to determine which web proxy to use depending on what websites are requested. In this post, we walk through step-by-step on how to configure Web Proxy PAC on an MTRoW device. Note that Microsoft strongly recommends that Teams media traffic should bypass web proxies as stated in this official doc as it may impact the network performance for real-time media. Nonetheless, organizations that require the use of Web Proxy for MTRoW devices may do so for normal web traffic. However, its important to note that MTRoW does not support web proxy authentication.
