I do not know if you have Cisco Wi-Fi phones (7821, 7925) or use Cisco softphones, but they use peer to peer connections for calls after the initial Call Manager setup. Microsoft Lync / Skype for Business uses peer to peer for calls on your local network rather than have both parties use an Internet server.

I am thinking about dropping P2P traffic for a main WLAN on WLC but I am not sure if that could break any application like zoom, remote desktop, file-sharing, wireless printers, Apple TV etc. Can anyone, who have implemented this, shed some light on this topic? Were applications similar to mentioned above affected after P2P traffic blocking ? Thanks, - Cheers, Tariq ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
