- Sign In Methods
User ID. Use this to sign in with user credentials on the Sign In screen. You cannot configure login credentials using the Polycom Web Configuration Utility.
▪ PIN Authentication. Use this to sign in on the phone or from the Web Configuration Utility. As of UC Software 5.1.1, this sign in method is available on the SoundStructure VoIP Interface. This option is available in on-premises Skype for Business deployments when you configure DCHP Option 43, and is not available for online deployments.
▪ Web Sign In for Skype for Business. For online deployments only, this method enables secure sign-in from a browser on your computer or mobile device. The phone generates a unique pairing code used to sign in on a secure Office 365 website. For more information about Web Sign In, refer to Web Sign In for Skype for Business Online.
▪ Sign In with Better Together over Ethernet (BToE). If you use the BToE feature in your
deployment, you can sign in to the phone from the PC client when the phone and computer are connected through the BToE application.
▪ Web Sign In CAP. Use this method to securely sign-in from a browser on your computer or mobile device when Common Area Phone mode feature is enabled along with Online Web Sign In and the phone is set to CAP Admin Mode. The phone generates a unique pairing code used to sign in on a secure Office 365 website.
▪ Single Sign-On Solutions (SSO). Allows you to use the same login credentials across multiple cloud-based applications such as Microsoft Exchange and Skype for Business.
Generic Enhancements:
- Wireless Network Connectivity
Polycom UC software supports wireless LAN connectivity by using Obihai USB Wi-Fi Dongle with all the VVX phones that support USB. Support for 2.4GHz or 5GHz

Limitations:
No other WiFi USB dongles are supported
No Video calls or IPv6
New VVX250, VVX350 or VVX450 cannot use USB Headset concurrently at present
No WiFi and Ethernet at the same time. The phone should be powered via a Power block but can be powered via PoE instead.
- Device Analytics via Polycom Device Management Service (PDMS)
You can configure the Device Analytics feature on your VVX phones to allow the phone to send device details to the analytics service in the cloud.
- Representational State Transfer API
VVX business media and business IP phones support Representational State Transfer (REST) API feature that enables you to execute certain functions and retrieve information using APIs.
For more information on these APIs, see REST API Reference Manual for Polycom VVX Business Media Phones at Polycom Engineering Advisories and Technical Notifications.
- Upload Logs to USB Storage Device
You can configure your phone to copy application and boot logs to a USB storage device connected to the phone. This will not work on a VVX1500. Details => here <=
- CTI via uaCSTA (user agent Computer Supported Telecommunications Applications) in line with TR-087.
When Polycom phones are configured to use uaCSTA with a CSTA server, end users can remotely control the phone and access phone services using a computer
telephony integration (CTI) application on their computer. To use CSTA, the IT Manager will need to set up a CSTA account and deploy CTI applications to the end users PC.
