Our initial testing of this device shows a number of issues and customer expectation are not met. This device is NOT supported.

• This device is not stand alone... it requires a VVX phone, running newest firmware, to handle the SIP portion of the call. So you must factor in the cost of a desk phone with Polycom's D60. Their manual states: "Compatible with Polycom® VVX® 300 series, 400 series, 500 series, and 600 series Business Media Phones".
• There isn't a feature to switch an active call back and forth from the DECT handset phone to the VVX or back.
• When the D60 is paired with the VVX device, a number of feature on the VVX device stop working... Most important is BLF! While the keys will appear, the state of the BLF is lost.
• It is not possible to use shared lines between the DECT phone and the VVX
• Updating the handset takes a VERY long time, the manual says 20 minutes. I can confirm that is about right! The firmware for the DECT phone is first downloaded into the VVX and when that is complete it sends it to the DECT phone and then the DECT phone take a very long time to restart after that. Best if you just keep it on the charger and let it be during that process.
• Requires Version 5 firmware which is now available using the "Ver 5" VVX device types in VCP.
• A number of provisioning setting must be changed or else the phones will loose pairing.
• Enable dect for D60 Handset must be set to Enable
• Dect File Path (Firmware) should be set to...

VVX D60 Wireless Handset Limitations

The following are limitations of using the VVX D60 wireless handset with the supported VVX business media phones:

• Hoteling, Busy Lamp Field (BLF), Enhanced Feature Keys, and Automatic Call Distribution (ACD) are not supported on the wireless handset, but these features are still available for the paired VVX business media phone. If ACD, Hoteling, and BLF is configured on a VVX+Dect line or a Dect only line, that line becomes a VVX only line. That is, the line will no longer be registered on VVX D60 handset as these features are not supported on VVX D60.
• Pairing a base station with a VVX business media phone with a VVX expansion module connected is not supported. If a VVX expansion module is connected to a VVX phone with a paired base station, the wireless handset is automatically unpaired from the VVX phone.
• Only shared lines on the BroadSoft BroadWorks server are supported on the wireless handsets.
• BroadSoft shared lines (SCA/SLA) can be assigned to either the VVX host phone or the wireless handset. A shared line assigned to the VVX host phone and a registered wireless handset cannot be a supported as a twinned line on the wireless handset.
• Call Park is only supported on the BroadSoft BroadWorks server for the wireless handsets.
• The VVX D60 feature and accessories are not supported in Microsoft Lync 2010, Lync 2013, or Skype for Business 2015 environments.
• The wireless handset supports SIP registered lines only. H.323 protocol is not supported on the wireless handset.
• Flexible Line Key customization is not available on VVX business media phones with a paired wireless handset.
• Outgoing calls placed on the wireless handset are not shown in the Recent Calls list on the VVX business media phones, and users cannot redial a call placed on the wireless handset from the VVX phone.
