We are using the Snom 300 with Snom HS MM headsets,(yes the switch and cable
are ground-signaled) all bought together. We are testing it for a call
center (100 seats) deploy and as i said first we are very disappointed with
the performace of them. Going to RMA them and get some Linksys 841.

The old product from Snom (360) runned headsed really well.
