Video Review of snom Vision Expansion Module for SIP and Lync





  • One of the first physical Lync Qualifed expansion module/attendant consoles for Microsoft Lync (snom 370 expansion module is another, Polycom has one but NOT qualified.)
  • Solid look and feel, nice build quality
  • Connects to phone via IP address (No USB needed)
  • Can be powered via POE (not 100% sure if this is pro or con. should it be USB?)


  • Bit slow paging between screens of extensions
  • Screen could show text-based Lync presence (ie: In a Call, In a Meeting, Inactive, etc)
  • Marketing show screen displaying Presence colors—you won’t find this in the live version

Some more points:

  • Red/Orange/Green colored BLF
  • full color, touch screen
  • 16 x 3 extension monitoring
  • connects to snom 8xx device via IP
  • Works with a variety SIP pbx's and Microsoft Lync
  • 2 USB ports (for future use?)
  • 2 bracket angles

  1. Matt,
    Thanks for all of your information on the SNOM devices. I'm currently installing one for a customer to test it as a frontdesk phone, but I can't seem to get presence to appear on the Vision. I've configured the device as you suggest above. We have also tried FW 1.2.4 and 1.2.5.

    Any suggestions?

    1. I solved my own problem. The user I was testing with needs to have the contacts in their Lync client contact list, as you mentioned above in reference to the SNOM 300 and 821.

    2. @Dave, glad my blog served you without my interference. ;-)
