Snom 8.8.3 BToE Beta Installation

This morning I received an email from Snom indicating the BToE beta has gone public.

The following are the steps I used to install snomXXX-UC- firmware on my 821 Snom phone and pair using Better Together over Ethernet (BToE) with Lync 2013 client on Windows 8.
Note: 821 was previously configured to register to Lync 2013 Server via Edge with my user account.

  1. Install Beta firmware using the phone’s admin page.
  2. Install BToE application on PC

  1. Pairing doesn’t require PC to be plugged into Phone, big for VDI and Remote Desktop scenarios.
  2. Command prompt running BteUrbDrMgr.exe must remain open or pairing disconnects.
